Appendix A - Firewall
STATEFUL PACKET INSPECTION
Refers to an architecture, where the firewall keeps track of packets on each
connection traversing all its interfaces and makes sure they are valid. This is in
contrast to static packet filtering which only examines a packet based on the
information in the packet header.
DENIAL OF SERVICE ATTACK
Is an incident in which a user or organization is deprived of the services of a
resource they would normally expect to have. Various DoS attacks the device can
withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf
Attack, and Tear Drop.
TCP/IP/PORT/INTERFACE FILTER
These rules help in the filtering of traffic at the Network layer (i.e. Layer 3).
When a Routing interface is created, Enable Firewall must be checked.
Navigate to Advanced Setup Security IP Filtering.
OUTGOING IP FILTER
Helps in setting rules to DROP packets from the LAN interface. By default, if the
Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more
filters, specific packet types coming from the LAN can be dropped.
Example 1: Filter Name : Out_Filter1
Protocol : TCP
Source IP address : 192.168.1.45
Source Subnet Mask : 255.255.255.0
Source Port : 80
Dest. IP Address : NA
Dest. Subnet Mask : NA
Dest. Port : NA
This filter will Drop all TCP packets coming from the LAN with IP
Address/Subnet Mask of 192.168.1.45/24 having a source port of 80
irrespective of the destination. All other packets will be Accepted.
Example 2: Filter Name : Out_Filter2
Protocol : UDP
Source IP Address : 192.168.1.45
Source Subnet Mask : 255.255.255.0
Source Port : 5060:6060
Dest. IP Address : 172.16.13.4
Dest. Subnet Mask : 255.255.255.0
Dest. Port : 6060:7070
This filter will drop all UDP packets coming from the LAN with IP Address /
Subnet Mask of 192.168.1.45/24 and a source port range of 5060 to 6060,
destined to 172.16.13.4/24 and a destination port range of 6060 to 7070.
INCOMING IP FILTER
Helps in setting rules to Allow or Deny packets from the WAN interface. By default,
all incoming IP traffic from the WAN is Blocked, if the Firewall is Enabled. By setting
up one or more filters, specific packet types coming from the WAN can be Accepted.
141
Example 1: Filter Name : In_Filter1
Protocol : TCP
Policy : Allow
Source IP Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 80
Dest. IP Address : NA
Dest. Subnet Mask : NA
Dest. Port : NA
Selected WAN interface : br0
This filter will ACCEPT all TCP packets coming from WAN interface “br0” with IP
Address/Subnet Mask 210.168.219.45/16 with a source port of 80, irrespective
of the destination. All other incoming packets on this interface are DROPPED.
Example 2: Filter Name : In_Filter2
Protocol : UDP
Policy : Allow
Source IP Address : 210.168.219.45
Source Subnet Mask : 255.255.0.0
Source Port : 5060:6060
Dest. IP Address : 192.168.1.45
Dest. Sub. Mask : 255.255.255.0
Dest. Port : 6060:7070
Selected WAN interface : br0
This rule will ACCEPT all UDP packets coming from WAN interface “br0” with IP
Address/Subnet Mask 210.168.219.45/16 and a source port in the range of
5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range
of 6060 to 7070. All other incoming packets on this interface are DROPPED.
MAC LAYER FILTER
These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in
Bridge mode. After a Bridge mode connection is created, navigate to Advanced
Setup Security MAC Filtering in the WUI.
Example 1: Global Policy : Forwarded
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : NA
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC
Address. All other frames on this interface are forwarded.
Example 2: Global Policy : Blocked
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : 00:34:12:78:90:56
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78 and Source MAC Address of
00:34:12:78:90:56. All other frames on this interface are dropped.

158
E2.1 PPP over ETHERNET (PPPoE)
STEP 1: Select the PPP over Ethernet radio button and click Next. You can also
enable IPv6 by ticking the checkbox at the bottom of this screen.
STEP 2: On the next screen, enter the PPP settings as provided by your ISP.
Click Next to continue or click Back to return to the previous step.
159
160
The settings shown above are described below.
PPP SETTINGS
The PPP Username, PPP password and the PPPoE Service Name entries are
dependent on the particular requirements of the ISP. The user name can be a
maximum of 256 characters and the password a maximum of 32 characters in
length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
DIAL ON DEMAND
The AR-5389 can be configured to disconnect if there is no activity for a period of
time by selecting the Dial on demand checkbox . You must also enter an
inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
 Allows only one PC on the LAN.
 Disables NAT and Firewall.
 The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
 The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
 The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
 The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox should not be selected to free up system
resources for better performance.
ENABLE FIREWALL
If this checkbox is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox
should not be selected to free up system resources for better performance.
161
USE STATIC IPv4 ADDRESS
Unless your service provider specially requires it, do not select this checkbox . If
selected, enter the static IP address in the IPv4 Address field.
Don’t forget to adjust the IP configuration to Static IP Mode as described in Section
3.2
MTU
Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which
the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS
(This option is hidden when PPP IP Extension is enabled)
When Enabled, this creates local PPPoE connections to the WAN side. Enable this
option only if all LAN-side devices are running PPPoE clients, otherwise disable it.
The VR-3025u supports pass-through PPPoE sessions from the LAN side while
simultaneously running a PPPoE client from non-PPPoE LAN devices.
ENABLE IGMP MULTICAST PROXY
Tick the checkbox to enable Internet Group Membership Protocol (IGMP)
multicast. This protocol is used by IPv4 hosts to report their multicast group
memberships to any neighboring multicast routers.
NO MULTICAST VLAN FILTER
Tick the checkbox to Enable/Disable multicast VLAN filter.
Enable WAN interface with base MAC
Enable this option to use the router’s base MAC address as the MAC address for this
WAN interface.
STEP 3: Choose an interface to be the default gateway.
162
Click Next to continue or click Back to return to the previous step.
Select DNS Server Interface from available WAN interfaces OR enter static DNS
server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or
static IPoE protocol is configured, Static DNS server IP addresses must be entered.
163
Click Next to continue or click Back to return to the previous step.
STEP 5: The WAN Setup - Summary screen shows a preview of the WAN service
you have configured. Check these settings and click Apply/Save if they
are correct, or click Back to modify them.
After clicking Apply/Save, the new service should appear on the main screen.
To activate it you must reboot. Go to Management Reboot and click Reboot.
164
E2.2 IP over ETHERNET (IPoE)
STEP 1: *Select the IP over Ethernet radio button and click Next.
*
For tagged service, enter valid 802.1P Priority and 802.1Q VLAN ID.
For untagged service, set -1 to both 802.1P Priority and 802.1Q VLAN ID.
STEP 2: The WAN IP settings screen provides access to the DHCP server settings.
You can select the Obtain an IP address automatically radio button to
enable DHCP (use the DHCP Options only if necessary). However, if you
prefer, you can instead use the Static IP address method to assign WAN
IP address, Subnet Mask and Default Gateway manually.
165
NOTE: If IPv6 networking is enabled, an additional set of instructions, radio
buttons, and text entry boxes will appear at the bottom of the screen.
These configuration options are quite similar to those for IPv4 networks.

checkbox . The NAT submenu will appear in the Advanced Setup menu after
reboot. On the other hand, if a private IP address is not used on the LAN side (i.e.
the LAN side is using a public IP), this checkbox should not be selected, so as to
free up system resources for improved performance.
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
ENABLE FIREWALL
If this checkbox is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox
should not be selected so as to free up system resources for better performance.

STEP 2: The WAN Setup - Summary screen shows a preview of the WAN service
you have configured. Check these settings and click Apply/Save if they
are correct, or click Back to return to the previous screen.
171
After clicking Apply/Save, the new service should appear on the main screen.
To activate it you must reboot. Go to Management Reboot and click Reboot.
NOTE: If this bridge connection is your only WAN service, the AR-5389 will be
inaccessible for remote management or technical support from the WAN.
172
E2.4 PPP over ATM (PPPoA)
STEP 1: Click Next to continue.
STEP 2: On the next screen, enter the PPP settings as provided by your ISP.
Click Next to continue or click Back to return to the previous step.
173
PPP SETTINGS
The PPP username and password are dependent on the requirements of the ISP.
The user name can be a maximum of 256 characters and the password a maximum
of 32 characters in length. (Authentication Method: AUTO, PAP, CHAP, or MSCHAP.)
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
174
DIAL ON DEMAND
The AR-5389 can be configured to disconnect if there is no activity for a period of
time by selecting the Dial on demand checkbox . You must also enter an
inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
 Allows only one PC on the LAN.
 Disables NAT and Firewall.
 The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
 The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
 The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
 The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox should not be selected to free up system
resources for better performance.
ENABLE FIREWALL
If this checkbox is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox
should not be selected to free up system resources for better performance.
USE STATIC IPv4 ADDRESS
Unless your service provider specially requires it, do not select this checkbox . If
selected, enter the static IP address in the IP Address field. Also, don’t forget to
adjust the IP configuration to Static IP Mode as described in Section 3.2.
Fixed MTU
Fixed Maximum Transmission Unit. The size (in bytes) of largest protocol data unit
which the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP DEBUG MODE
