Product Overview
Thank you for choosing the Cisco Small Business RV 110W Wireless-N VPN
Firewall. The Cisco RV 110W is an advanced Internet-sharing network solution for
your small business needs. It allows multiple computers in your office to share an
Internet connection through both wired and wireless connections.
The Cisco RV 110W provides a Wireless-N access point, combined with support
for Virtual Private Networks (VPNs) to make your network more secure. Its 10/100
Ethernet WAN interface connects directly to your broadband DSL or Cable
modem. There are four full-duplex 10/100 Ethernet LAN interfaces that can
connect up to four devices. The wireless access point supports the 802.11n
standard with MIMO technology, which multiplies the effective data rate. This

Introduction
Product Overview
The Cisco RV 110W incorporates a Stateful Packet Inspection (SPI)-based firewall
with Denial of Service (DoS) prevention and a Virtual Private Network (VPN)
engine for secure communication between mobile or remote workers and branch
offices. The Cisco RV 110W supports up to ten gateway-to-gateway IP Security
(IPsec) tunnels to facilitate branch office connectivity through encrypted virtual
links. Users connecting through a VPN tunnel are attached to your company’s
network with secure access to files, e-mail, and your intranet as if they were in the
building. You can also use the VPN capability to allow users on your small office
network to securely connect out to a corporate network
The Cisco RV 110W’s wireless access point supports Wireless Distribution
System (WDS), which allows the wireless coverage to be expanded without wires.
It also supports multiple SSIDs for the use of virtual networks (up to 4 separate
virtual networks), with 802.1Q-based VLAN support for traffic separation. The
Cisco RV 110W implements WPA2-PSK, WPA2-ENT, and WEP encryption, along
with other security features including the disabling of SSID broadcasts, MACbased filtering, and allowing or denying “time of day” access per SSID. The Cisco
RV 110W supports Wi-Fi Multimedia (WMM) and Wi-Fi Multimedia Power Save
(WMM-PS) for wireless Quality of Service (QoS). It supports 802.1p, Differentiated
Services Code Point (DSCP), and Type of Service (ToS) for wired QoS, which can
improve the quality of your network when using delay-sensitive Voice over IP
(VoIP) applications and bandwidth-intensive video streaming applications.
With the Cisco RV 110W’s embedded web server, its settings can be configured
using the browser-based Device Manager. The Cisco RV 110W supports Internet
Explorer, Firefox, and Safari web browsers. The Cisco RV 110W also provides a
setup wizard and VPN wizard. The setup wizard allows you to easily configure the
Cisco RV 110W’s basic settings. You can use the VPN wizard to easily configure
VPN tunnels.

NOTE Before configuring any WAN properties for an IPv6 network, you must configure the
routing mode. Choose Networking > IPv6 > Routing Mode and select IPv4 / IPv6
mode. Click Save.
The Cisco RV 120W can be configured to be a DHCPv6 client of the ISP for this
WAN or a static IPv6 address provided by the ISP can be assigned.
Configuring a Static IP Address
If your ISP assigns you a fixed address to access the Internet, choose this option.
The information needed for configuring a static IP address can be obtained from
your ISP.
STEP 1 In the Internet Address field, choose Static IPv6.
STEP 2 Enter the IPv6 IP address assigned to your router.
STEP 3 Enter the IPv6 prefix length defined by the ISP. The IPv6 network (subnet) is
identified by the initial bits of the address which are called the prefix (for example,
in the IP address 2001:0DB8:AC10:FE01::, 2001 is the prefix). All hosts in the
network have identical initial bits for their IPv6 address; the number of common
initial bits in the network’s addresses is set in this field.
STEP 4 Enter the default IPv6 gateway address, or the IP address of the server at the ISP
that this router will connect to for accessing the internet.
Cisco RV 120W Administration Guide
34
Configuring Networking
Configuring the Wide Area Network (WAN)
STEP 5 Enter the primary and secondary DNS server IP addresses on the ISP's IPv6
network. DNS servers map Internet domain names (for example, www.cisco.com)
to IP addresses.
STEP 6 Choose the method by which the router obtains an IP address:
STEP 7 Click Save.
Configuring DHCPv6
When the ISP allows you to obtain the WAN IP settings via DHCP, you need to
provide details for the DHCPv6 client configuration.
STEP 1 In the Internet Address field, choose DHCPv6.
STEP 2 Choose if the DHCPv6 client on the gateway is stateless or stateful. If a stateful
client is selected, the gateway connects to the ISP's DHCPv6 server for a leased
address. For stateless DHCP, it is not necessary to have a DHCPv6 server
available at the ISP. Instead, a ICMPv6 discover messages will originate from the
Cisco RV 120W and is used for auto-configuration.
STEP 3 Click Save.
Creating PPPoE Profiles
You can create profiles for multiple PPPoE accounts, which can be useful if you
connect to the Internet using different service provider accounts.
STEP 1 Choose Networking > WAN > PPPoE Profiles. Click Add to create a new profile.
STEP 2 Enter the profile name. This is a label that you choose to identify the profile (for
example, “ISPOne”).
STEP 3 Enter the username and password. These are assigned to you by the ISP to
access your account.
STEP 4 Choose the authentication type:
•
Cisco RV 120W Administration Guide
Auto-negotiate—The server sends a configuration request specifying the
security algorithm set on it. The router then sends back authentication
credentials with the security type sent earlier by the server.
35
Configuring Networking
Configuring the Local Area Network (LAN)
•
PAP—The Cisco RV 120W uses Password Authentication Protocol when
connecting with the ISP.
•
CHAP—The Cisco RV 120W uses Challenge Handshake Authentication
Protocol when connecting with the ISP.
•
MS-CHAP or MS-CHAPv2—The Cisco RV 120W uses Microsoft Challenge
Handshake Authentication Protocol when connecting with the ISP.
STEP 5 Choose the connectivity type:
•
Keep connected—The Internet connection is always on.
•
Idle Time—The Internet connection is on only when traffic is present. If the
connection is idle—that is, no traffic is occurring—the connection is closed.
You might want to choose this if your ISP charges based on the amount of
time that you are connected.
If you choose this connection type, enter the number of minutes after which
the connection shuts off in the Idle Time field.
STEP 6 Click Save. Your new profile is added to the list.
Configuring the Local Area Network (LAN)
For most applications, the default DHCP and TCP/IP settings are satisfactory. If
you want another PC on your network to be the DHCP server, or if you are
manually configuring the network settings of all of your PCs, disable DHCP.
Instead of using a DNS server, you can use a Windows Internet Naming Service
(WINS) server. A WINS server is the equivalent of a DNS server but uses the
NetBIOS protocol to resolve hostnames. The router includes the WINS server IP
address in the DHCP configuration when acknowledging a DHCP request from a
DHCP client.
You can also enable a DNS proxy. When enabled, the router then acts as a proxy
for all DNS requests and communicates with the ISP's DNS servers. When
disabled, all DHCP clients receive the DNS IP addresses of the ISP.
Cisco RV 120W Administration Guide
36
Configuring Networking
Configuring the Local Area Network (LAN)
If machines on your LAN use different IP address ranges (for example, 172.16.2.0
or 10.0.0.0), you can add aliases to the LAN port to give PCs on those networks
access to the Internet. This allows the firewall to act as a gateway to additional
logical subnets on your LAN. You can assign the firewall an IP address on each
additional logical subnet.
NOTE If you have IPv6 configured, see “Configuring IPv6 LAN Properties” on page 43.
Changing the Default Cisco RV 120W IP Address
STEP 1 Choose Networking > LAN > LAN Configuration.
STEP 2 In the IP address field, enter the new IP address for your Cisco RV 120W. The
default IP address is 192.168.1.1. You might want to change the default IP address
if that address is assigned to another piece of equipment in your network.
STEP 3 Enter the Subnet Mask for the new IP address.
STEP 4 Click Save. After changing the IP address, you are no longer connected to the
Cisco RV 120W. You must do one of the following:
•
Release and renew the IP address on the PC that you are using to access
the Cisco RV 120W (if DHCP is configured on the router).
•
Manually assign an IP address to your PC that is in the same subnet as the
Cisco RV 120W. For example, if you change the Cisco RV 120W IP address
to 10.0.0.1, you would assign an IP address in the 10.0.0.0 subnet to your PC.
STEP 5 Open a new browser window and enter the new IP address of the Cisco RV 120W
to re-connect.
Configuring DHCP
By default, the Cisco RV 120W functions as a DHCP server to the hosts on the
Wireless LAN (WLAN) or LAN network and assigns IP and DNS server addresses.
With DHCP enabled, the router's IP address serves as the gateway address to
your LAN. The PCs in the LAN are assigned IP addresses from a pool of addresses.
Each address is tested before it is assigned to avoid duplicate addresses on the
LAN.

Configuring a DMZ Host
The Cisco RV 120W supports DMZ options. A DMZ is a sub-network that is open
to the public but behind the firewall. DMZ allows you to redirect packets going to
your WAN port IP address to a particular IP address in your LAN. It is
recommended that hosts that must be exposed to the WAN (such as web or e-mail
servers) be placed in the DMZ network. Firewall rules can be allowed to permit
access to specific services and ports to the DMZ from both the LAN or WAN. In the
event of an attack on any of the DMZ nodes, the LAN is not necessarily vulnerable
as well.

You must configure a fixed (static) IP address for the endpoint that will be
designated as the DMZ host. The DMZ host should be given an IP address in the
same subnet as the router's LAN IP address but it cannot be identical to the IP
address given to the LAN interface of this gateway.
STEP 1 Choose Networking > LAN > DMZ Host.
STEP 2 Check the Enable box to enable DMZ on the network.
STEP 3 Enter the IP address for the endpoint that will receive the redirected packets. This

STEP 4 Click Save. You must then configure firewall rules for the zone. See Configuring
Firewall Rules, page 79.
Configuring Internet Group Management Protocol (IGMP)
Internet Group Management Protocol (IGMP) is an exchange protocol for routers.
Hosts that want to receive multicast messages need to inform their neighboring
routers of their status. In some networks, each node in a network becomes a
member of a multicast group and receives multicast packets. In these situations,
hosts exchange information with their local routers using IGMP. Routers use IGMP
periodically to check if the known group members are active. IGMP provides a
method called dynamic membership by which a host can join or leave a multicast
group at any time.
To configure IGMP:
STEP 1 Choose Networking > LAN > IGMP Configuration.
STEP 2 Check the Enable box to allow IGMP communication between the router and other
nodes in the network.

Choosing the Routing Mode
The Cisco RV 120W provides two different routing modes. Network Address
Translation (NAT) is a technique that allows several endpoints on a LAN to share an
Internet connection. The computers on the LAN use a “private” IP address range
while the WAN port on the router is configured with a single “public” IP address.
The Cisco RV 120W translates the internal private addresses into a public
address, hiding internal IP addresses from computers on the Internet. If your ISP
has assigned you a single IP address, you want to use NAT so that the computers
that connect through the Cisco RV 120W are assigned IP addresses from a private
subnet (for example, 192.168.10.0).
The other routing mode, “classical routing,” is used if your ISP has assigned you
multiple IP addresses so that you have an IP address for each endpoint on your
network. You must configure either static or dynamic routes if you use this type of
routing. See Configuring Static Routing, page 49, or Configuring Dynamic
Routing, page 50.
To choose your routing mode:
STEP 1 Select Networking > Routing > Routing Mode.
STEP 2 Click the box next to the type of routing to configure (“NAT” or “Routing”) and click
Save.
NOTE If you have already configured DMZ or firewall settings on your router in NAT mode,
selecting “router” changes those settings back to the default.
Viewing Routing Information
To view routing information your network, choose Networking > Routing > Routing
Table. Information about your network routing is displayed, including the following:

Destination—Destination host/network IP address for which this route is
added.
•
Gateway—The gateway used for this route.

Configuring Networking
Configuring Routing
•
Genmask—The netmask for the destination network.
•
Flags—For debugging purpose only; possible flags include:
U—Route is up.
H—Target is a host.
G—Use gateway.
R—Reinstate route for dynamic routing.
D—Dynamically installed by daemon or redirect.
M—Modified from routing daemon or redirect.
A—Installed by addrconf.
C—Cache entry.
!—Reject route.
•
Metric—The distance to the target (usually counted in hops).
•
Ref—Number of references to this route.
•
Use—Count of lookups for the route. Depending on the use of -F and -C, this
is either route cache misses (-F) or hits (-C).
•
Iface—Interface to which packets for this route will be sent.
Configuring Static Routing
You can configure static routes to direct packets to the destination network. A
static route is a pre-determined pathway that a packet must travel to reach a
specific host or network. Some ISPs require static routes to build your routing
table instead of using dynamic routing protocols. Static routes do not require CPU
resources to exchange routing information with a peer router. You can also use
static routes to reach peer routers that do not support dynamic routing protocols.
Static routes can be used together with dynamic routes. Be careful not to
introduce routing loops in your network.
To create a static route:
STEP 1 Select Networking > Routing > Static Routing.
STEP 2 In the list of static routes, click Add.

STEP 3 Enter the route name.
STEP 4 If a route is to be immediately active, check the Active box. When a route is added
in an inactive state, it will be listed in the routing table, but will not be used by the
router. The route can be enabled later. This feature is useful if the network that the
route connects to is not available when you added the route. When the network
becomes available, the route can be enabled.
STEP 5 Check the Private box to mark this route as private, which means that it will not be
shared in a Routing Information Protocol (RIP) broadcast or multicast. Uncheck this
box if the route can be shared with other routers when RIP is enabled.
STEP 6 In the destination IP address field, enter the IP address of the destination host or
network to which the route leads. For a standard Class C IP domain, the network
address is the first three fields of the Destination LAN IP; the last field should be
zero.

STEP 9 In the gateway IP address field, enter the IP Address of the gateway through
which the destination host or network can be reached. If this router is used to
connect your network to the Internet, then your gateway IP is the router's IP

Configuring Dynamic Routing
RIP (Routing Information Protocol, RFC 2453) is an Interior Gateway Protocol (IGP)
that is commonly used in internal networks. It allows the router to exchange its
routing information automatically with other routers, and allows it to dynamically
adjust its routing tables and adapt to changes in the network.

STEP 2 To configure how the router sends and receives RIP packets, choose the RIP
direction:
•
Both—The router both broadcasts its routing table and also processes RIP
information received from other routers.
•
Out Only—The router broadcasts its routing table periodically but does not
accept RIP information from other routers.
•
In Only—The router accepts RIP information from other router, but does not
broadcast its routing table.
•
None—The router neither broadcasts its route table nor does it accept any
RIP packets from other routers. This option disables RIP.
STEP 3 Choose the RIP version:
•
Disabled.
•
RIP-1—This is a class-based routing version that does not include subnet
information. RIP-1 is the most commonly supported version.
•
RIP-2B—This version broadcasts data in the entire subnet.
•
RIP-2M—This version sends data to multicast addresses.
STEP 4 RIP v2 authentication forces authentication of RIP packets before routes are
exchanged with other routers. It acts as a security feature because routes are
exchanged only with trusted routers in the network. RIP authentication is disabled
by default. You can enter two key parameters so that routes can be exchanged
with multiple routers present in the network. The second key also acts as a failsafe
when authorization with first key fails.
To enable authentication for RIP-2B or RIP-2M, check the Enable box. (You must

host is unreachable. By default, the routing update is sent every 30 seconds. If the
router receives no routing updates from a neighbor after 180 seconds, the routes
learned from the neighbor are considered as unreachable. After another 240
seconds, if no routing update is received, the router will remove these routes from
the routing table.
On the Cisco RV 120W, RIPng is disabled by default.
To configure RIPng:
STEP 1 Select Networking > IPv6 > Routing (RIPng).
STEP 2 Check the Enable RIPng box.
STEP 3 Click Save.
Configuring IPv6 to IPv4 Tunneling
The Cisco RV 120W provides several IPv6 tunneling methods.
Configuring 6to4 Tunneling
6to4 tunneling allows IPv6 packets to be transmitted over an IPv4 network. 6to4
tunneling is typically used when a site or end user wants to connect to the IPv6
Internet using the existing IPv4 network.
To configure 6to4 Tunneling:
STEP 1 Select Networking > IPv6 > 6to4 Tunneling.
STEP 2 Check the Enable Automatic Tunneling box.
STEP 3 Click Save.
Configuring Intra-Site Automatic Tunnel Addressing Protocol Tunnels
Intra-site automatic tunnel addressing protocol is a method to transmit IPv6
packets between dual-stack nodes over an IPv4 network. The Cisco RV 120W is
one endpoint (a node) for the tunnel. You must also set a local endpoint, as well as
the ISATAP Subnet Prefix that defines the logical ISATAP subnet to configure a
tunnel.
Cisco RV 120W Administration Guide

Configuring Networking
Configuring IPv6
To add an ISATAP tunnel:
STEP 1 Choose Networking > IPv6 > ISATAP Tunnels.
STEP 2 Click Add.
STEP 3 Enter the ISATAP subnet prefix. This is the 64-bit subnet prefix that is assigned to
the logical ISATAP subnet for this intranet. This can be obtained from your ISP or
internet registry, or derived from RFC 4193.
STEP 4 Choose the local endpoint address, or the endpoint address for the tunnel that
starts with the Cisco RV 120W. The endpoint can be the LAN interface (if the LAN
is configured as an IPv4 network), or a specific LAN IPv4 address.
STEP 5 If you chose an endpoint other than the LAN interface in Step 4, enter the IPv4
address of the endpoint.
STEP 6 Click Save.
Viewing IPv6 Tunnel Information
To view IPv6 tunnel information, choose Networking > IPv6 > IPv6 Tunnels Status.
The page displays information about the automatic tunnel set up through the
dedicated WAN interface. The table shows the name of tunnel and the IPv6
address that is created on the device.
Configuring Router Advertisement
The Router Advertisement Daemon (RADVD) on the Cisco RV 120W listens for
router solicitations in the IPv6 LAN and responds with router advertisements as
required. This is stateless IPv6 auto configuration, and the Cisco RV 120W
distributes IPv6 prefixes to all nodes on the network.
To configure the RADVD:
STEP 1 Choose Networking > IPv6 > Router Advertisement.
STEP 2 Under RADVD Status, choose Enable.
STEP 3 Under Advertise Mode, choose one of the following:
•
Cisco RV 120W Administration Guide
Unsolicited Multicast—Select this option to send router advertisements
(RAs) to all interfaces belonging to the multicast group.
57

Configuring Networking
Configuring IPv6
•
Unicast only—Select this option to restrict advertisements to well-known
IPv6 addresses only (router advertisements [RAs] are sent to the interface
belonging to the known address only).
STEP 4 If you chose Unsolicited Multicast in Step 3, enter the advertise interval. The
advertise interval is a random value between the Minimum Router Advertisement
Interval and Maximum Router Advertisement Interval. (MinRtrAdvInterval = 0.33 *
MaxRtrAdvInterval.) The default is 30 seconds.
STEP 5 Under RA Flags, check Managed to use the administered/stateful protocol for
address auto configuration. Check Other to use the administered/stateful protocol
of other, non-address information auto configuration.
STEP 6 Under router preference, choose low, medium, or high. The router preference
provides a preference metric for default routers. The low, medium and high values
are signaled in unused bits in Router Advertisement messages. This extension is
backward compatible, both for routers (setting the router preference value) and
hosts (interpreting the router preference value). These values are ignored by hosts
that do not implement router preference. This feature is useful if there are other
RADVD-enabled devices on the LAN. The default is high.
STEP 7 Enter the MTU size. The MTU is the size of the largest packet that can be sent over
the network. The MTU is used in RAs to ensure all nodes on the network use the
same MTU value when the LAN MTU is not well-known. The default is 1500 bytes.
STEP 8 Enter the router lifetime value, or the time in seconds that the advertisement
messages will exist on the route. The default is 3600 seconds.
STEP 9 Click Save.
To configure the RADVD available prefixes:
STEP 1 Choose Networking > IPv6 > Advertisement Prefixes.
STEP 2 Click Add.
STEP 3 Choose the IPv6 Prefix Type:
•
6to4—6to4 is a system that allows IPv6 packets to be transmitted over an
IPv4 network. It is used when an end user wants to connect to the IPv6
Internet using their existing IPv4 connection
•
Global/ISATAP—By using ISATAP, you can integrate IPv6 traffic into a IPv4
network environment. ISATAP uses a locally assigned IPv4 address to
create a 64-bit interface identifier for IPv6.

58
Configuring Networking
Configuring IPv6
STEP 4 If you chose 6to4 in Step 3, enter the Site-level aggregation identifier (SLA ID.) The
SLA ID in the 6to4 address prefix is set to the interface ID of the interface on which
the advertisements are sent.
If you chose Global/Local/ISATAP in Step 3, enter the IPv6 prefix and prefix
length. The IPv6 prefix specifies the IPv6 network address. The prefix length
variable is a decimal value that indicates the number of contiguous, higher-order
bits of the address that make up the network portion of the address.
STEP 5 Enter the prefix lifetime, or the length of time over which the requesting router is
allowed to use the prefix.
STEP 6 Click Save.

A Note About Wireless Security
Wireless networks are convenient and easy to install, so homes with high-speed
Internet access are adopting them at a rapid pace. Because wireless networking
operates by sending information over radio waves, it can be more vulnerable to
intruders than a traditional wired network. Like signals from your cellular or
cordless phones, signals from your wireless network can also be intercepted. The
following information will help you to improve your security:
•
Wireless Security Tips, page 60
•
General Network Security Guidelines, page 62
Wireless Security Tips
Since you cannot physically prevent someone from connecting to your wireless
network, you need to take some additional steps to keep your network secure:
Cisco RV 120W Administration Guide
60
Configuring the Wireless Network
A Note About Wireless Security
•
Change the default wireless network name or SSID
Wireless devices have a default wireless network name or Service Set
Identifier (SSID) set by the factory. This is the name of your wireless
network, and can be up to 32 characters in length.
You should change the wireless network name to something unique to
distinguish your wireless network from other wireless networks that may
exist around you, but do not use personal information (such as your Social
Security number) because this information may be available for anyone to
see when browsing for wireless networks.
•
Change the default password
For wireless products such as access points, routers, and gateways, you
will be asked for a password when you want to change their settings. These
devices have a default password set by the factory. The default password
is often admin. Hackers know these defaults and may try to use them to
access your wireless device and change your network settings. To thwart
any unauthorized changes, customize the device’s password so it will be
hard to guess.
•
Enable MAC address filtering
Cisco routers and gateways give you the ability to enable Media Access
Control (MAC) address filtering. The MAC address is a unique series of
numbers and letters assigned to every networking device. With MAC
address filtering enabled, wireless network access is provided solely for
wireless devices with specific MAC addresses. For example, you can
specify the MAC address of each computer in your network so that only
those computers can access your wireless network.
Cisco RV 120W Administration Guide
61
Configuring the Wireless Network
A Note About Wireless Security
•
Enable encryption
Encryption protects data transmitted over a wireless network. Wi-Fi
Protected Access (WPA/WPA2) and Wired Equivalency Privacy (WEP) offer
different levels of security for wireless communication. Currently, devices
that are Wi-Fi certified are required to support WPA2, but are not required
to support WEP.
A network encrypted with WPA/WPA2 is more secure than a network
encrypted with WEP, because WPA/WPA2 uses dynamic key encryption.
To protect the information as it passes over the airwaves, you should
enable the highest level of encryption supported by your network
equipment.
WEP is an older encryption standard and may be the only option available
on some older devices that do not support WPA.
•
Keep wireless routers, access points, or gateways away from exterior walls
and windows.
•
Turn wireless routers, access points, or gateways off when they are not
being used (at night, during vacations).
•
Use strong passphrases that are at least eight characters in length.
Combine letters and numbers to avoid using standard words that can be
found in the dictionary.
General Network Security Guidelines
Wireless network security is useless if the underlying network is not secure. Cisco
recommends that you take the following precautions:
•
Password protect all computers on the network and individually password
protect sensitive files.
•
Change passwords on a regular basis.
•
Install anti-virus software and personal firewall software.
•
Disable file sharing (peer-to-peer). Some applications may open file sharing
without your consent and/or knowledge.

Configuring the Wireless Network
Understanding the Cisco RV 120W’s Wireless Networks
Understanding the Cisco RV 120W’s Wireless Networks
The Cisco Small Business RV 120W Wireless-N VPN Firewall provides four
Wireless Access Points (APs), or virtual wireless networks. These networks can be
configured and enabled with individual settings. You can set up multiple networks
to segment the network traffic, to allow different levels of access, such as guest
access, or to allow access for different functions such as accounting, billing, and so
on.
You can further customize wireless access by creating profiles. A profile is a set of
generic wireless settings that can be shared across multiple APs. Profiles allow
you to easily duplicate SSIDs, security settings, encryption methods, and client
authentication for multiple APs.
Configuring Wireless Profiles
A profile is a set of generic wireless settings that can be shared across multiple
APs. You can create multiple profiles on the Cisco RV 120W, but only one profile is
assigned to each AP at a time.
The Cisco RV 120W provides four default wireless profiles. Even if you are not
going to create custom profiles, at a minimum, you should edit the default profiles
to enable wireless security. See A Note About Wireless Security, page 60.
To configure wireless profiles:
STEP 1 Choose Wireless > AP Profiles.
STEP 2 In the Profiles Table, either click Add to add a new profile, or check the box in the
row of an existing profile and click Edit.
STEP 3 If creating a new profile, enter a unique name to identify the profile.
STEP 4 In the SSID field, enter a unique name for this wireless network. Include up to 32
characters, using any of the characters on the keyboard. For added security, you
should change the default value to a unique name.
STEP 5 Check the Broadcast SSID box if you want to allow all wireless clients within range
to be able to detect this wireless network when they are scanning the local area
for available networks. Disable this feature if you do not want to make the SSID
known. When this feature is disabled, wireless users can connect to your wireless
network only if they know the SSID (and provide the required security credentials).
Cisco RV 120W Administration Guide
63
Configuring the Wireless Network
Configuring Wireless Profiles
STEP 6 In the Security field, select the type of security. All devices on your network must
use the same security mode and settings to work correctly. Cisco recommends
using the highest level of security that is supported by the devices in your network.
•
Disabled—Any device can connect to the network. Not recommended.
•
Wired Equivalent Privacy (WEP)— Weak security with a basic encryption
method that is not as secure as WPA. WEP may be required if your network
devices do not support WPA; however, it is not recommended.
•
Wi-Fi Protected Access (WPA) Personal—WPA is part of the wireless
security standard (802.11i) standardized by the Wi-Fi Alliance and was
intended as an intermediate measure to take the place of WEP while the
802.11i standard was being prepared. It supports TKIP/AES encryption.
The personal authentication is the preshared key (PSK) that is an
alphanumeric passphrase shared with the wireless peer.
•
WPA Enterprise—Allows you to use WPA with RADIUS server
authentication.
•
WPA2 Personal—WPA2 is the implementation of security standard
specified in the final 802.11i standard. It supports AES encryption and this
option uses preshared key (PSK) based authentication.
•
WPA2 Personal Mixed—Allows both WPA and WPA2 clients to connect
simultaneously using PSK authentication.
•
WPA2 Enterprise—Allows you to use WPA2 with RADIUS server
authentication.
•
WPA2 Enterprise Mixed—Allows both WPA and WPA2 clients to connect
simultaneously using RADIUS authentication.
STEP 7 Perform the following steps based on the type of encryption you chose in Step 6:
WPA/WPA2
a. Select the encryption method to be used: TKIP, AES, or TKIP+AES.
b. Select the authentication method to be used: R ADIUS, PSK, or PSK + RADIUS.
c. WPA Password—Enter the pre-shared key for WPA/WPA2 PSK authentication.
The clients also need to be configured with the same password.
d. (Optional) Check the Enable Pre-Authentication box to enable preauthentication for this profile. Pre-authentication allows wireless clients to
quickly switch between connected Access Points sharing the same security
configuration. This is mainly used when APs are configured with WPA/WPA2
Cisco RV 120W Administration Guide
64
Configuring the Wireless Network
Configuring Wireless Profiles
security. In event of wireless client disconnecting from an AP, a notification is
sent to the AP, which then sends the pre-authentication info to other APs in the
network.
WEP
In the WEP Index and Keys section:
a. In the Authentication field, choose Open System or Shared Key. If you choose
open system, a wireless client doesn't need to provide a shared key in order to
access the wireless network. Any client can associate to the router. If you
choose shared key, a wireless client must provide the correct shared key
(password) in order to access the wireless network.
b. Select the encryption type (6
64- or 128-bit). The larger size keys provide
stronger encryption, making the key more difficult to crack (for example, 64-bit
WEP has a 40-bit key which is less secure than the 128-bit WEP, which has a
104-bit key).
c. (Optional) In the passphrase field, enter an alphanumeric phrase (longer than
eight characters for optimal security) and click Generate Key to generate four
unique WEP keys in the WEP Key fields below.
d. Select one of the four to use as the shared key that devices must have in order
to use the wireless network. If you did not generate a key in Step C, enter a key
directly into the WEP Key field. The length of the key should be 5 ASCII
characters (or 10 hexadecimal characters) for 64-bit WEP and 13 ASCII
characters (or 26 hexadecimal characters) for 128-bit WEP. Valid hexadecimal
characters are “0” to “9” and “A” to “F”.
STEP 8 Click Save.
Configuring the Group Key Refresh Interval
If you configure WPA or WPA2 security, you can specify the timeout interval after
which group keys are generated:
STEP 1 Choose Wireless > AP Profile.
STEP 2 Check the box in the row of the profile you want to configure and click Advanced
Configuration.
STEP 3 Enter the group key refresh interval, in seconds.

Configuring Access Points
STEP 4 Click Save.
Configuring RADIUS Authentication Parameters
In WPA2 security, Pairwise Master Key Security Association (PMKSA) caching is
used to store the master keys derived from successful RADIUS authentication. A
client reconnecting within this interval (after successful RADIUS authentication)
can skip the RADIUS authentication. This feature prevents a long RADIUS
authentication process every time a client connects.
To configure:
STEP 1 Choose Wireless > AP Profile.
STEP 2 Check the box in the row of the profile you want to configure and click Advanced
Configuration.
STEP 3 Specify the number of seconds that the master keys are stored in the AP.
STEP 4 In the 802.1X re-authentication interval field, enter the timeout interval (in seconds)
after which the AP should re-authenticate with the RADIUS server.
STEP 5 Click Save.
Configuring Access Points
To configure the APs, choose Wireless > AP Profiles. The four APs are displayed
in the Access Points Table.
Enabling or Disabling APs
An AP can be disabled if not in use and enabled when needed. Disabling an AP
does not delete the configuration, but removes it from availability. Enabling the AP
creates a wireless network, where computers and other devices can join and
communicate with the devices connected to the AP or other devices on the Local
Area Network (LAN).

multiple boxes.
Editing an AP’s Properties
You can edit properties for an AP to make it only available at certain times of the
day, restrict the number of endpoints that can use the AP, or separate the AP from
the other wireless networks in the Cisco RV 120W.
To edit the properties of an access point:
STEP 1 Choose Wireless > AP Profiles.
STEP 2 Check the box in the row of the AP that you want to edit.
STEP 3 Associate a profile with this AP by choosing the profile from the Profile Name list.
The profile controls the name and security settings for the AP. See Configuring
the Wireless Radio Properties, page 70.
STEP 4 (Optional) To configure the AP to be active only during a certain time of day, check
the Active Time box. Enter the start and stop times (hours, minutes, and AM/PM).
STEP 5 In the Max Associated Clients field, enter the maximum number of endpoints that
can use this AP. The default value is 8. You can change this number if you want to
restrict traffic on the network to prevent it from being overloaded, for example.
STEP 6 (Optional) Check the AP Isolation box to separate this AP into its own network.
When this feature is enabled, the AP can communicate with the Cisco RV 120W,
but not with any other AP on the network.

Configuring the Wireless Radio Properties
You can configure radio card properties, including the wireless standard (for
example, 802.11n or 802.11g) on the Cisco RV 120W.
Configuring Basic Wireless Radio Settings
STEP 1 Choose Wireless > Radio Settings > Radio Settings.
STEP 2 Select the Wireless Network Mode:
•
B/G Mixed—Select this mode if you have devices in the network that
support 802.11b.
•
G Only—Select this mode if all devices in the wireless network only support
802.11g.
•
N/G Mixed—Select this mode if you have devices in the network that
support 802.11g and 802.11n.
•
N Only—Select this mode if all devices in the wireless network support
802.11n.
STEP 3 Select the channel bandwidth. Available choices depend on the wireless network
mode chosen in Step 2.
STEP 4 The control sideband field defines the sideband which is used for the secondary
or extension channel when the AP is operating in 40 Mhz channel width. Choose
lower or upper. This field is only available when channel spacing is set to auto. The
signal components above the carrier frequency constitute the upper sideband
(USB) and those below the carrier frequency constitute the lower sideband (LSB).
STEP 5 The channel field specifies the frequency that the radio uses to transmit wireless
frames. Select a channel from the list of channels or choose auto to let the Cisco
RV 120W determine the best channel to use based on the environment noise
levels for the available channels.
STEP 6 Click Save.
Cisco RV 120W Administration Guide
70
Configuring the Wireless Network
Configuring the Wireless Radio Properties
Configuring Advanced Wireless Radio Settings
STEP 1 Choose Wireless > Radio Settings > Radio Settings.
STEP 2 In the beacon interval field, enter the time in milliseconds between beacon
transmissions. The default interval is 100 milliseconds.
STEP 3 In the DTIM interval field, enter the interval at which the delivery traffic indication
message should be sent. A DTIM field is a countdown field informing clients of the
next window for listening to broadcast and multicast messages. When the Cisco
RV 120W has buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and
awaken to receive the broadcast and multicast messages.The default interval is 2
beacon intervals.
STEP 4 The Request to Send (RTS) threshold is the packet size, in bytes, that requires the
AP to check the transmitting frames to determine if an RTS/Clear to Send (CTS)
handshake is required with the receiving client. Using a small value causes RTS
packets to be sent more often, consuming more of the available bandwidth,
reducing the apparent throughput of the network packets. The default value is
2346, which effectively disables RTS.
STEP 5 The fragmentation threshold is the maximum length of the frame, in bytes, beyond
which packets must be fragmented into two or more frames. Collisions occur more
often for long frames because while sending them, they occupy the channel for a
longer time. The default value is 2346, which effectively disables fragmentation. If
you experience a high packet error rate, you can slightly increase the
fragmentation threshold; setting the fragmentation threshold too low may result in
poor network performance. Only minor reduction of the default value is
recommended.
STEP 6 Choose the preamble mode. The 802.11b standard requires that a preamble be
appended to every frame before it is transmitted through the air. The preamble
may be either the traditional “long” preamble, which requires 192 s for
transmission, or it may be an optional “short” preamble that requires only 96 s. A
long preamble is needed for compatibility with the legacy 802.11 systems
operating at 1 and 2 Mbps. The default selection is long.
STEP 7 Choose the protection mode. Select none (the default) to turn off CTS. The CTS-
to-Self Protection option enables the CTS-to-Self protection mechanism, which is
used to minimize collisions among stations in a mixed 802.11b and 802.11g
environment. This function boosts the Cisco RV 120W’s ability to catch all wireless
transmissions but severely decreases performance.

Cisco RV 110W Firewall Features
•
Schedules as to when the router should apply rules.
•
Keywords (in a domain name or on a URL of a web page) that the router
should allow or block.
•
Rules for allowing or blocking inbound and outbound Internet traffic for
specified services on specified schedules.
•
MAC addresses of devices whose inbound access to your network the
router should block.
•
Port triggers that signal the router to allow or block access to specified
services as defined by port number.
•
Reports and alerts that you want the router to send to you.
You can, for example, establish restricted-access policies based on time-of-day,
web addresses, and web address keywords. You can block Internet access by
applications and services on the LAN, such as chat rooms or games. You can block
just certain groups of PCs on your network from being accessed by the WAN or
public DMZ network.
Inbound (WAN to LAN/DMZ) rules restrict access to traffic entering your network,
selectively allowing only specific outside users to access specific local resources.
By default, all access from the insecure WAN side is blocked from accessing the
secure LAN, except in response to requests from the LAN or DMZ. To allow
outside devices to access services on the secure LAN, you must create a firewall
rule for each service.
If you want to allow incoming traffic, you must make the router's WAN port IP
address known to the public. This is called “exposing your host.” How you make
your address known depends on how the WAN ports are configured; for the Cisco
RV 120W, you may use the IP address if a static address is assigned to the WAN
port, or if your WAN address is dynamic, a DDNS (Dynamic DNS) name can be
used.
Outbound (LAN/DMZ to WAN) rules restrict access to traffic leaving your network,
selectively allowing only specific local users to access specific outside resources.
The default outbound rule is to allow access from the secure zone (LAN) to either
the public DMZ or insecure WAN. To block hosts on the secure LAN from
accessing services on the outside (insecure WAN), you must create a firewall rule
for each service.

Configuring Basic Firewall Settings
Configuring Basic Firewall Settings
To configure basic firewall settings, choose Firewall > Basic Settings. You can
configure the following:
Protecting from Attacks
Attacks are malicious security breeches or unintentional network issues that
render the Cisco RV 120W unusable. Attack checks allow you to manage WAN
security threats such as continual ping requests and discovery via ARP scans. TCP
and UDP flood attack checks can be enabled to manage extreme usage of WAN
resources.
As well, certain Denial-of-Service (DoS) attacks can be blocked. These attacks, if
uninhibited, can use up processing power and bandwidth and prevent regular
network services from running normally. ICMP packet flooding, SYN traffic
flooding, and Echo storm thresholds can be configured to temporarily suspect
traffic from the offending source.
STEP 1 Choose Firewall > Basic Settings > Attack Checks.
STEP 2 Check the boxes to enable the following functions:
WAN Security
•
Respond to Ping on the Internet—To configure the Cisco RV 120W to allow
a response to an Internet Control Message Protocol (ICMP) Echo (ping)
request on the WAN interface, check this box. This setting is used as a
diagnostic tool for connectivity problems. Not enabled by default.
•
Enable Stealth Mode—If Stealth Mode is enabled, the router will not
respond to port scans from the WAN. This feature makes the network less
susceptible to discovery and attacks. Enabled by default.
•
Block TCP Flood— If this option is enabled, the router will drop all invalid
TCP packets. This feature protects the network from a SYN flood attack.
Enabled by default.
LAN Security
•
Cisco RV 120W Administration Guide
Block UDP Flood—If this option is enabled, the router will not accept more
than 25 simultaneous, active UDP connections from a single computer on
the LAN. Enabled by default.

STEP 6 Choose the action:
•
Always Block—Always block the selected type of traffic.
•
Always Allow—Never block the selected type of traffic.
•
Block by schedule, otherwise allow—Blocks the selected type of traffic
according to a schedule. See Creating Firewall Schedules, page 85.
•
Allow by schedule, otherwise block—Allows the selected type of traffic
according to a schedule. See Creating Firewall Schedules, page 85.
STEP 7 In the Source Hosts field, select the users to which the firewall rule applies:
•
Any—The rule applies to traffic originating on any host in the local network.
•
Single Address—The rule applies to traffic originating on a single IP
address in the local network. Enter the address in the From field.
•
Address Range—The rule applies to traffic originating from an IP address
located in a range of addresses. Enter the starting IP address in the From
field, and the ending IP address in the To field.
STEP 8 In the Log field, specify whether or not the packets for this rule should be logged.
To log details for all packets that match this rule, select Always. For example, if an
outbound rule for a schedule is selected as Block Always, then for every packet
that tries to make an outbound connection for that service, a message with the
packet’s source address and destination address (and other information) is
recorded in the log. Enabling logging may generate a significant volume of log
messages and is recommended for debugging purposes only. Select Never to
disable logging.
STEP 9 When traffic is going from the LAN or DMZ to the WAN, the system requires
rewriting the source or destination IP address of incoming IP packets as they pass
through the firewall. In the SNAT IP Type field, choose WAN Interface Address or
choose Single Address and enter the Single IP Address in the SNAT IP field.
STEP 10 In the QoS Priority field, assign a priority to IP packets of this service. The priorities
are defined by “Type of Service (TOS) in the Internet Protocol Suite” standards,
RFC 1349. The gateway marks the Type Of Service (TOS) field as defined below:
•
Cisco RV 120W Administration Guide
Normal-Service—No special priority is given to the traffic. The IP packets
for services with this priority are marked with a TOS value of 0.
82
4
Configuring the Firewall
Configuring Firewall Rules
•
Minimize-Cost—Choose this option when data must be transferred over a
link that has a lower “cost.” The IP packets for services with this priority are
marked with a TOS value of 2.
•
Maximize-Reliability—Choose this option when data needs to travel to the
destination over a reliable link and with little or no retransmission. The IP
packets for services with this priority are marked with a TOS value of 4.
•
Maximize-Throughput—Choose this option when the volume of data
transferred during an interval is important even if the latency over the link is
high. The IP packets for services with this priority are marked with a TOS
value of 8.
•
Minimize-Delay—Choose this option when the time required (latency) for
the packet to reach the destination must be low. The IP packets for services
with this priority are marked with a TOS value of 16.
STEP 11 When the traffic is coming from the WAN to the DMZ or the LAN, Destination
Network Address Translation maps a public IP address (your Dedicated WAN
address, Optional WAN address, or another address) to an IP address on your
private network. Enter the following:
•
Send to Local Server (DNAT IP)—Specify an IP address of a machine on the
Local Network which is hosting the server.
•
(Optional) Check the Enable Port Forwarding box to enable port forwarding
to the port that you specify in the Translate Port Number field. This will allow
traffic from the Internet to reach the appropriate LAN port via a port
forwarding rule.
•
Translate Port Number—Enter the port number to use for port forwarding.
For example, if a machine on the Local Network side is running a telnet
server on port 2000, then check the Enable Port Forwarding box and enter
2000 in the Translate Port Number field. If the server is listening on the
default port 23, then the box can be left unchecked.
•
Internet Destination Address—Select the public IP address that is used for
this firewall rule: Dedicated WAN, Optional WAN, or Other. If you choose
Other, enter the WAN IP address that will map to the internal server in the
Other IP Address field.
Cisco RV 120W Administration Guide

Configuring the Firewall
Configuring Firewall Rules
This gateway supports multi-NAT, and the Internet Destination IP address does
not necessarily have to be the WAN address. On a single WAN interface,
multiple public IP addresses are supported. If your ISP assigns you more than
one public IP address, one of these can be used as your primary IP address on
the WAN port, and the others can be assigned to servers on the LAN or DMZ.
In this way, the LAN/DMZ server can be accessed from the internet by its
aliased public IP address.
STEP 12 Click Save.
Managing Firewall Rules
Choose Firewall > Access Control > IPv4 Rules.
To enable or disable a rule, check the box next to the rule in the list of firewall rules
and choose Enable or Disable.
To delete a rule, check the box next to the rule and click Delete.
To reorder rules, check the box next to a rule and click Up or Down. The Cisco RV
120W applies rules in the order listed. As a general rule, you should move the
strictest rules (those with the most specific services or addresses) to the top of the
list.
Creating Custom Services
When you create a firewall rule, you can specify a service that is controlled by the
rule. Common types of services are available for selection, and you can create
your own custom services. This page allows creation of custom services against
which firewall rules can be defined. Once defined, the new service will appear in
the List of Available Custom Services table.
To create a custom service:
STEP 1 Choose Firewall > Access Control > Services.
STEP 2 Enter a service name for identification and management purposes.
STEP 3 Enter the service type, or layer 4 protocol that the service uses (T
TCP, UDP, ICMP,
or ICMPv6).
STEP 4 If you chose ICMP or ICMPv6 as the service type, enter the ICMP type. This is a
numeric value from 0 through 40 for ICMP and from 0 through 255 for ICMPv6.

STEP 5 Click Save.
Blocking and Filtering Content and Applications
The Cisco RV 120W supports several content filtering options. You can block
certain web applications or components (such as ActiveX or Java). You can set up
trusted domains from which to always allow content. You can block access to
Internet sites by specifying keywords to block. If these keywords are found in the
site's name (for example, web site URL or newsgroup name), the site is blocked.

Configuring the Firewall
Blocking and Filtering Content and Applications
You also need to turn on content filtering to set up trusted domains.
Blocking Web Applications and Components
STEP 1 Choose Firewall > Access Control > Content Filtering.
STEP 2 Check the Enable box.
STEP 3 Certain commonly-used web components can be blocked for increased security.
Some of these components can be used by malicious websites to infect
computers that access them. With content filtering enabled, select the check box
for each component you wish to block:
•
Proxy—A proxy server (or simply, proxy) allows computers to route
connections to other computers through the proxy, thus circumventing
certain firewall rules. For example, if connections to a specific IP address
are blocked by a firewall rule, the requests can be routed through a proxy
that is not blocked by the rule, rendering the restriction ineffective. Enabling
this feature blocks proxy servers.
•
Java—Blocks java applets from being downloaded from pages that contain
them. Java applets are small programs embedded in web pages that
enable dynamic functionality of the page. A malicious applet can be used to
compromise or infect computers. Enabling this setting blocks Java applets
from being downloaded.
•
ActiveX—Similar to Java applets, ActiveX controls are installed on a
Windows computer while running Internet Explorer. A malicious ActiveX
control can be used to compromise or infect computers. Enabling this
setting blocks ActiveX applets from being downloaded.

Blocking and Filtering Content and Applications
•
Cookies—Cookies are used to store session information by websites that
usually require login. However, several websites use cookies to store
tracking information and browsing habits. Enabling this option filters out
cookies from being created by a website.
NOTE Many websites require that cookies be accepted in order for the site to be

STEP 4 Click Save.
Adding Trusted Domains
You can add a list of trusted domains. These domains are bypassed during
keyword filtering. For example, if “yahoo” is added to the blocked keywords list
and www.yahoo.com is added to the trusted domain list, then www.yahoo.com
will be allowed, but mail.yahoo.com will not be allowed.
NOTE Before adding trusted domains, you must enable content filtering. See Blocking
Web Applications and Components, page 86.
To add trusted domains:
STEP 1 Choose Firewall > Access Control > Trusted Domains.
STEP 2 Enter the trusted domain.
STEP 3 Click Save.

STEP 4 Select the group to which to apply the keyword blocking. (These groups are
configured in the Networking > LAN > LAN Groups page.)
STEP 5 Click Save.
Configuring MAC Address Filtering
MAC address filtering allows you to block traffic coming from certain known
machines or devices. The router uses the MAC address of a computer or device
on the network to identify it and block or permit the access. Traffic coming in from
a specified MAC address will be filtered depending upon the policy.
To enable MAC address filtering:
STEP 1 Choose Firewall > Access Control > MAC Filtering.
STEP 2 Check the Enable box to enable MAC Address Filtering for this device. Uncheck
the box to disable this feature.
If you enable MAC filtering, in the Policy for MAC Address listed below field,
choose one of the following options:
•
Block and Permit the rest—Choose this option to block the traffic from the
specified MAC addresses and to allow traffic from all other addresses.
•
Permit and Block the rest—Choose this option to permit the traffic from the
specified MAC addresses and to block traffic from all other machines on the
LAN side of the router.
For example, two computers are on the LAN with MAC addresses of
00:01:02:03:04:05 (host1), and 00:01:02:03:04:11 (host2). If the host1 MAC address
is added to the MAC filtering list and the “block and permit the rest” policy is
chosen, when this computer tries to connect to a website, the router will not allow
Cisco RV 120W Administration Guide
88
Configuring the Firewall
Blocking and Filtering Content and Applications
it to connect. However, host2 is able to connect because its MAC address is not in
the list. If the policy is “permit and block the rest,” then host1 is able to connect to a
website, but host2 is blocked because its URL is not in the list. The MAC filtering
policy does not override a firewall rule that directs incoming traffic to a host.
STEP 3 Click Save.
STEP 4 In the MAC Addresses table, click Add.
STEP 5 Enter the MAC address to add to the table and click Save. Repeat for each
address to permit or block.
Configuring IP/MAC Address Binding
IP/MAC Binding allows you to bind IP addresses to MAC address. Some machines
are configured with static addresses. To prevent users from changing static IP
addresses, IP/MAC Binding should be enabled. If the Cisco RV 110W sees
packets with matching IP address but inconsistent MAC addresses, it drops those
packets.
To configure IP/MAC Address binding:
STEP 1 Choose Firewall > Access Control > IP/MAC Binding. The table lists all the
currently defined IP/MAC binding rules and allows several operations on the rules.
STEP 2 Click Add to add a new rule.
STEP 3 In the name field, enter the name for this rule.
STEP 4 In the MAC Addresses field, enter the MAC Addresses (the physical address of the
piece of hardware) for this rule.
STEP 5 In the IP Addresses field, enter the IP Addresses to assign to the piece of
hardware.
STEP 6 In the Log Dropped Packets field, choose if you want to log the dropped packets.
Choosing enable logs the dropped packets. Logs can be viewed in Status > View

Example 3: Multi-NAT Configuration
In this example, you want to configure multi-NAT to support multiple public IP
addresses on one WAN port interface.
Create an inbound rule that configures the firewall to host an additional public IP
address. Associate this address with a web server on the DMZ. If you arrange with
your ISP to have more than one public IP address for your use, you can use the
additional public IP addresses to map to servers on your LAN. One of these public
IP addresses is used as the primary IP address of the router. This address is used
to provide Internet access to your LAN PCs through NAT. The other addresses are
available to map to your DMZ servers.
The following addressing scheme is used to illustrate this procedure:
•
WAN IP address: 10.1.0.118
•
LAN IP address: 192.168.1.1; subnet 255.255.255.0

remote users).
STEP 1 Setup a schedule. Choose Firewall > Access Control > Schedules.
STEP 2 Enter Weekend in the Name field.
STEP 3 Under Scheduled Days, choose Specific Days.
STEP 4 Check the box next to Saturday and Sunday.

12:00 a.m. to 11:59 p.m. of the selected days.
STEP 6 Click Save.
Configuring Port Triggering
Port triggering allows devices on the LAN or DMZ to request one or more ports to
be forwarded to them. Port triggering waits for an outbound request from the LAN/
DMZ on one of the defined outgoing ports, and then opens an incoming port for
that specified type of traffic. Port triggering is a form of dynamic port forwarding
while an application is transmitting data over the opened outgoing or incoming
ports.
Cisco RV 120W Administration Guide
92
Configuring the Firewall
Configuring Port Triggering
Port triggering opens an incoming port for a specific type of traffic on a defined
outgoing port.
Port triggering is more flexible than static port forwarding (available when
configuring firewall rules) because a rule does not have to reference a specific
LAN IP or IP range. Ports are also not left open when not in use, thereby providing a
level of security that port forwarding does not offer.
NOTE
Port triggering is not appropriate for servers on the LAN, since there is a
dependency on the LAN device making an outgoing connection before incoming
ports are opened.
Some applications require that, when external devices connect to them, they
receive data on a specific port or range of ports in order to function properly. The
router must send all incoming data for that application only on the required port or
range of ports. The gateway has a list of common applications and games with
corresponding outbound and inbound ports to open. You can also specify a port
triggering rule by defining the type of traffic (TCP or UDP) and the range of
incoming and outgoing ports to open when enabled.
To add a port triggering rule:
STEP 1 Choose Firewall > Port Triggering.
STEP 2 Click Add.
STEP 3 Specify an easily-identifiable name for this rule.
STEP 4 Check the Enable box to enable the rule.
STEP 5 Select whether the port uses TCP or UDP protocol.
STEP 6 In the Outgoing (Trigger) Port Range section, specify the port number or range of
port numbers that will trigger this rule when a connection request from outgoing

Configuring Port Forwarding
Port forwarding is used to redirect traffic from the Internet from one port on the
WAN to another port on the LAN. The port forwarding rules menu allows selection
of a service. Common services are available or you can define a custom service
and associated ports to forward.
The Port Forwarding Rules table lists all the available port forwarding rules for this
device and allows you to configure port forwarding rules. The table contains the
following information:
•
Status—A port forwarding rule can be disabled if not in use and enabled
when needed. The port forwarding rule is disabled if the status is disabled
and it is enabled if the status is enabled. Disabling a port forwarding rule
does not delete the configuration.
•
Service—Service for which this port forwarding rule is applicable.
•
Action—Whether to block or allow traffic (always or by schedule) that
meets these filter rules, and when the rule is applicable.
•
Source Users—The source IP for this port forwarding rule (Any, Single,
Range, or Host name).
•
Local Server—The DNAT IP address, if traffic that meets this filter rule is
sent to a local server.
•
Internet Destination—Which of the WAN ports (if more than one is available)
that is the Internet destination for traffic covered by this port forwarding
rule.
•
Log—Whether this port forwarding rule is logged (always or never).
To configure port forwarding:

Configuring VPNs
A VPN provides a secure communication channel (“tunnel”) between two gateway
routers or a remote PC client and a gateway router. The following types of tunnels
can be created:
•
Gateway-to-gateway VPN—Connects two or more routers to secure traffic
between remote sites.
•
Remote Client (client-to-gateway VPN tunnel)—A remote client initiates a
VPN tunnel. The IP address of the remote PC client is not known in advance.
The gateway acts as responder.
•
Remote client behind a NAT router—The client has a dynamic IP address
and is behind a NAT Router. The remote PC client at the NAT router initiates
a VPN tunnel. The IP address of the remote NAT router is not known in
advance. The gateway WAN port acts as a responder.
Creating Cisco QuickVPN Client Users
To use the Cisco QuickVPN, you must do the following:
STEP 1 Enable remote management. See Configuring Remote Management, page 98.
STEP 2 Create QuickVPN users. See Configuring IPsec Users, page 114. After a user
account is created, the credentials can be used by the QuickVPN client.
For more information on installing and using Cisco QuickVPN, see Appendix A,
“Using Cisco QuickVPN for Windows 2000, XP, or Vista.”
Using the VPN Wizard
You can use the VPN wizard to quickly create both IKE and VPN policies. Once the
IKE or VPN policy is created, you can modify it as required.

Configuring IP Security Policies
The VPN Wizard is the recommended method to configure corresponding IKE and
VPN policies for establishing a VPN tunnel. Once the Wizard creates the matching
IKE and VPN policies, you can modify the required fields using the Edit button.
Advanced users can create an IKE policy from the Add button, but must be sure to
use compatible encryption, authentication, and key-group parameters for the VPN
policy.
Configuring IKE Policies
The Internet Key Exchange (IKE) protocol dynamically exchanges keys between
two IPsec hosts. You can create IKE policies to define the security parameters
such as authentication of the peer, encryption algorithms, etc. to be used in this
process.
To configure IKE Policies:.
STEP 1 Choose VPN > IPsec > IPsec Policies.
STEP 2 In the IKE Policies Table, click Add.
STEP 3 Enter the information in the following sections and press Save.
General Information
STEP 1 Under Policy Name, enter a unique name for the policy for identification and
management purposes.
STEP 2 Under Direction/Type, choose one of the following connection methods:
•
Initiator—The router will initiate the connection to the remote end.
•
Responder—The router will wait passively and respond to remote IKE
requests.
•
Both—The router will work in either Initiator or Responder mode.
STEP 3 Under Exchange Mode, choose one of the following options:
•
Main mode—This mode negotiates the tunnel with higher security, but is
slower.
•
Aggressive mode—This mode establishes a faster connection, but with
lowered security.
Cisco RV 120W Administration Guide
105
Configuring Virtual Private Networks (VPNs) and Security
Configuring VPNs
NOTE If either the Local or Remote identifier type is not an IP address, then
negotiation is only possible in Aggressive Mode. If FQDN, User FQDN or DER
ASN1 DN is selected, the router disables Main mode and sets the default to
Aggressive mode.
STEP 4 In the Local section, under Identifier Type, choose the ISAKMP identifier for this
router:
•
Local WAN IP
•
Internet Address/FQDN
•
User FQDN
•
DER ASN1 DN
STEP 5 If you chose Internet Address/FQDN, User FQDN, or DER ASN1 DN as the identifier
type, enter the IP address or domain name in the Identifier field.
STEP 6 In the Remote section, under Identifier Type, choose the ISAKMP identifier for this
router:
•

STEP 2 Specify the authentication algorithm for the VPN header:
•
MD5
•
SHA-1
•
SHA2-256
•
SHA2-384
•
SHA2-512
NOTE Ensure that the authentication algorithm is configured identically on both
sides.
STEP 3 Choose the authentication method:
•
Select Pre-Shared Key for a simple password based key that is shared with
the IKE peer.
•
Selecting RSA-Signature disables the pre-shared key text box and uses the
Active Self Certificate uploaded in the Certificates page. In that case, a
certificate must be configured in order for RSA-Signature to work.
NOTE The double quote character (“) is not supported in the pre-shared key.
STEP 4 Choose the Diffie-Hellman (DH) Group algorithm, which is used when exchanging
keys. The DH Group sets the strength of the algorithm in bits.
NOTE Ensure that the DH Group is configured identically on both sides of the IKE
policy.
STEP 5 In the SA Lifetime field, enter the interval, in seconds, after which the Security
Association becomes invalid.

STEP 6 To enable dead peer detection, check the box. Dead Peer Detection is used to
detect whether the peer is alive or not. If peer is detected as dead, the router
deletes the IPsec and IKE Security Association.
STEP 7 In the Detection Period field, enter the interval, in seconds, between consecutive
DPD R-U-THERE messages. DPD R-U-THERE messages are sent only when the
IPsec traffic is idle.
STEP 8 In the Reconnect after Failure Count field, enter the maximum number of DPD
failures allowed before tearing down the connection.
Extended Authentication (XAUTH) Parameters
Rather than configuring a unique VPN policy for each user, you can enable the VPN
gateway router to authenticate users from a stored list of user accounts or with an
external authentication server such as a RADIUS server. When connecting many
VPN clients to a VPN gateway router, Extended Authentication (XAUTH) allows
authentication of users with methods in addition to the authentication method
mentioned in the IKE SA parameters. XAUTH can be configured in the following
modes:
STEP 1 Select the XAUTH type:
•
None—Disables XAUTH.
•
IPsec Host—The router is authenticated by a remote gateway with a
username and password combination. In this mode, the router acts as a VPN
Client of the remote gateway.
•
User Database—User accounts created in the router are used to
authenticate users. See Configuring IPsec Users, page 114.
STEP 2 If you selected IPsec Host, enter the username and password for the host.
Configuring VPN Policies
To configure a VPN policy:
STEP 1 Choose VPN > IPsec > IPsec Policies.

Auto Policy Parameters
STEP 1 SA Lifetime—Enter the duration of the Security Association and choose the unit
from the drop-down list:
•
Seconds—Choose this option to measure the SA Lifetime in seconds. After
the specified number of seconds passes, the Security Association is
renegotiated. The default value is 3600 seconds. The minimum value is 300
seconds.
•
Kbytes—Choose this option to measure the SA Lifetime in kilobytes. After
the specified number of kilobytes of data is transferred, the SA is
renegotiated. The minimum value is 1920000 KB.
NOTE When configuring a Lifetime in kilobytes (also known as lifebytes), be aware
that two SAs are created for each policy. One SA applies to inbound traffic,
and one SA applies to outbound traffic. Due to differences in the upstream
and downstream traffic flows, the SA may expire asymmetrically. For
example, if the downstream traffic is very high, the lifebyte for a download
stream may expire frequently. The lifebyte of the upload stream may not
expire as frequently. It is recommended that the values be reasonably set, to
reduce the difference in expiry frequencies of the SAs; otherwise the
system may eventually run out of resources as a result of this asymmetry.
The lifebyte specifications are generally recommended for advanced users
only.
STEP 2 Select the algorithm used to encrypt the data.
STEP 3 Select the algorithm used to verify the integrity of the data.
STEP 4 Check the PFS Key Group box to enable Perfect Forward Secrecy (PFS) to
improve security. While slower, this protocol helps to prevent eavesdroppers by

Configuring Virtual Private Networks (VPNs) and Security
Configuring VPNs
Configuring VPN Clients
VPN clients must be configured with the same VPN policy parameters used in the
VPN tunnel the client wishes to use: encryption, authentication, life time, and PFS
key-group. Upon establishing these authentication parameters, the VPN Client
user database must also be populated with an account to give a user access to
the tunnel.
VPN client software is required to establish a VPN tunnel between the router and
remote endpoint. Open source software (such as OpenVPN or Openswan) as well
as Microsoft IPsec VPN software can be configured with the required IKE policy
parameters to establish an IPsec VPN tunnel. Refer to the client software guide for
detailed instructions on setup as well as the router’s online help.
The user database contains the list of VPN user accounts that are authorized to
use a given VPN tunnel. Alternatively VPN tunnel users can be authenticated using
a configured RADIUS database. Refer to the online help to determine how to
populate the user database and/or configure RADIUS authentication.
Monitoring VPN Tunnel Status
You can view and change the status of (connect or drop) the router’s IPsec security
associations. The VPN tunnel status can be found in the Status > IPsec Connection
Status page. Here the active IPsec SAs (security associations) are listed along
with the traffic details and tunnel state. The traffic is a cumulative measure of
transmitted/received packets since the tunnel was established.
If a VPN policy state is “not connected”, it can be enabled from the List of VPN
Policies in the VPN > IPsec > IPsec Policies page.

Configuring Security
The Cisco RV 110W provides several security methods, including certificate
authentication, RADIUS server support, and 802.1x port-based authentication.
Using Certificates for Authentication
The Cisco RV 110W uses digital certificates for IPsec VPN authentication and SSL
validation (for HTTPS and SSL VPN authentication). You can obtain a digital
certificate from a well-known Certificate Authority (CA) such as VeriSign, or
generate and sign your own certificate using functionality available on this
gateway. The gateway comes with a self-signed certificate, and this can be
replaced by one signed by a CA as per your networking requirements. A CA
certificate provides strong assurance of the server's identity and is a requirement
for most corporate network VPN solutions.
Cisco RV 120W Administration Guide
115
Configuring Virtual Private Networks (VPNs) and Security
Configuring Security
The certificates menu allows you to view a list of certificates (both from a CA and
self-signed) currently loaded on the gateway. The following certificate data is
displayed in the list of Trusted (CA) certificates:
•
CA Identity (Subject Name)—The certificate is issued to this person or
organization.
•
Issuer Name—The name of the Certificate Authority that issued this
certificate.
•
Expiry Time—The date after which this Trusted certificate becomes invalid.
A self certificate is a certificate issued by a CA identifying your device (or selfsigned if you don't want the identity protection of a CA). The Active Self Certificate
table lists the self certificates currently loaded on the gateway. The following
information is displayed for each uploaded self certificate:
•
Name—The name you use to identify this certificate. It is not displayed to
IPsec VPN peers or SSL users.
•
Subject Name—This is the name that is displayed as the owner of this
certificate. This should be your official registered or company name, as
IPsec or SSL VPN peers are shown this field.
•
Serial Number—The serial number is maintained by the CA and used to
identify this signed certificate.
•
Issuer Name—This is the CA name that issued (signed) this certificate
•
Expiry Time—The date after which this signed certificate becomes invalid you should renew the certificate before it expires.
To request a self certificate to be signed by a CA, you can generate a Certificate
Signing Request from the gateway by entering identification parameters and
sending to the CA for signing. Once signed, the CA's Trusted Certificate and
signed certificate from the CA are uploaded to activate the self-certificate
validating the identity of this gateway. The self certificate is then used in IPsec and
SSL connections with peers to validate the gateway's authenticity.
To configure certificates, choose Security > Authentication (Certificates).

Configuring Quality of Service (QoS)
The Cisco RV 110W provides configuration for QoS features, such as bandwidth
profiles, traffic selectors, and traffic meters. It contains the following sections:
•
Configuring Bandwidth Profiles, page 120
•
Configuring Traffic Flows, page 121
•
Configuring Traffic Metering, page 122
•
Configuring 802.1p, page 124
Configuring Bandwidth Profiles
Using bandwidth profiles, the bandwidth of the traffic flowing from the secure
network (LAN) to the insecure network (WAN) can be shaped. Bandwidth limiting
determines the speed from which the data is sent from your router. You can use a
bandwidth profile to limit the outbound traffic, thus preventing the LAN users from
consuming all of the bandwidth of the Internet link.
Bandwidth profiles configuration consists of enabling the bandwidth control
feature from the Device Manager, and adding a profile which defines the control
parameters. The profile can then be associated with a traffic selector, so that
bandwidth profile can be applied to the traffic matching the selectors.
To configure bandwidth profiles, perform the following steps.
Enable Bandwidth Profiles
STEP 1 Choose QoS > Bandwidth Profiles.
STEP 2 Check the Enable box.
STEP 3 Click Save.

Bonjour is a service advertisement and discovery protocol. For the Cisco RV
110W, Bonjour only advertises the default services configured on the device when
Bonjour is enabled.
To configure Bonjour:
STEP 1 Choose Administration > Discovery Settings > Discovery - Bonjour.
STEP 2 Check the Enable box to enable Bonjour on the router. Unchecking this will disable
Bonjour.
Currently the services csco-sb and http are available and active by default. When

Configuring Date and Time Settings
Configuring VLAN Associations
You can select the available VLAN to enable Bonjour service types. Available
VLANs are populated for the Bonjour Association VLAN list after the VLANs are
configured for the device. (See Configuring Virtual LANs (VLANs), page 39, for
more information.) Currently, by default, LAN/Default-VLAN is the broadcasting
domain for service.
Associating a VLAN allows devices present on the VLAN to discover Bonjour
services available on the router (such as http/https). For example, if a VLAN is
configured with an ID of 2, devices and hosts present on VLAN 2 cannot discover
Bonjour services running on the router unless VLAN 2 is associated with Bonjour
services.
To add a VLAN association:
STEP 1 Choose Administration > Discovery Settings > VLAN Association.
STEP 2 Click Add.
STEP 3 Choose an available VLAN to which to add a service. (See Configuring Virtual
LANs (VLANs), page 39 for more information.)
STEP 4 Click Save. The VLAN is added to the VLAN Association Table.
Configuring Date and Time Settings
You can configure your time zone, whether or not to adjust for Daylight Savings
Time, and with which Network Time Protocol (NTP) server to synchronize the date
and time. The router then gets its date and time information from the NTP server.
To configure NTP and time settings:
STEP 1 Choose Administration > Time Settings.
STEP 2 Select your time zone, relative to Greenwich Mean Time (GMT).
STEP 3 If supported for your region, check the Adjust for Daylight Savings Time box.
STEP 4 Select whether to use default or custom Network Time Protocol (NTP) servers, or
set the time and date manually.

Backing Up and Restoring the System
STEP 5 If you chose a default NTP server, choose the server from the list. If you chose a
custom NTP server, enter the server addresses or fully-qualified domain name.
If you chose to set the date and time manually, enter the date and time.
STEP 6 Click Save.
Backing Up and Restoring the System
You can back up custom configuration settings for later restoration or restore from
a previous backup from the Administration > Backup/Restore Settings page.
When the router is working as configured, you can back up the configuration for
restoring later. During backup, your settings are saved as a file on your PC. You
can restore the router's settings from this file.
CAUTION During a restore operation, do not try to go online, turn off the router, shut down the
PC, or do anything else to the router until the operation is complete. This should
take about a minute. When the test light turns off, wait a few more seconds before
doing anything with the router.
To back up a configuration or restore a previously-saved configuration:
STEP 1 Select Administration > Backup/Restore Settings.
STEP 2 To save a copy of your current settings, click Backup. The browser downloads the
configuration file and prompts you to save the file on the PC.
To restore your saved settings from a backup file, click Browse, locate and select
the file, and click Restore. An alert page displays the status of the restore
operation. After the restore, the router restarts automatically with the restored
settings.
