PC Network Configuration and Login
PC Network Configuration
Each network interface on the PC should either be configured with a statically defined
IP address and DNS address, or be instructed to automatically obtain an IP address
using the network DHCP server. BCM3384 provides a DHCP server on its LAN and it
is recommended to configure your LAN to automatically obtain its IP address and
DNS server IP address.
The configuration principle is identical but should be carried out differently on each
operating system.
The following displays the TCP/IP Properties dialog box on Windows XP.

5.2.1
Setup
Choose Basic > Setup , and the following page appears.
Figure 8 Setup configuration
Enter the information from the Required Information section as indicated:
1.If your ISP uses DHCP, select “DHCP” for the WAN Connection Type, and enter
Host Name and Domain name if required. OR
14
SR808ac Cable Modem User Manual
If your ISP uses static IP addressing, select “Static IP” for the WAN Connection
Type, and enter the information provided by your ISP for Static IP Address, Static
IP Mask, Default Gateway, Primary DNS, and Secondary DNS.
2.Enter a unicast MAC address in the Spoofed MAC Address field. Your ISP may
require this to be your PC’s MAC address. If not, you can simply supply the WAN
side MAC address of the router as your CPE and leave the spoofed MAC address
entry set to all 0’s, since there will be no spoofing required.
3.Select the Apply button. This will reset the CMRG.
At this point, the CMRG is configured for basic use. To connect to the Internet,
you must do the following:
1.Power up the CMRG and wait for it to register with the CMTS and obtain an
Internet-routable IP address
2.Get an IP lease from the internal DHCP server for each PC attached to the
CMRG.
Note that communication on the LAN will work regardless of whether the WAN
connection provided by the cable modem is up. However, you will not be able to
access the Internet until the WAN connection is enabled and has an IP address.
Some configurations settings are retrieved only once from non-volatile storage
when the CMRG first powers up. One such setting is changing the Static WAN IP
address parameters. Any changes to these settings will force the CMRG to reset
so that the new configuration can be read from non-volatile storage.
When this mandatory reset is required, the web interface will notify as follows:
15
SR808ac Cable Modem User Manual
Figure 9 Reload page
Simply wait for the modem to reboot and click on the “Reload” link to re-enter the
web interface where you made your last change.
Most configuration items may be changed on the fly without a reboot.
5.2.2
DHCP
Choose Basic > DHCP, and the following page appears.
Figure 10 DHCP configuration
This page allows configuration and status of the optional internal DHCP server for the
LAN.
If you have your own DHCP server servicing the LAN side (or choose to “hardcode”
all of your PC’s IP addresses), you can disable the internal DHCP server by selecting
the No radio button. If you do this, make sure the IP address assigned to the CMRG
is on the same subnet as the external DHCP server (the subnet mask is always
255.255.255.0), or you won’t be able to access the CMRG from the LAN. The IP
address of the CMRG can be set from the Basic Setup page.
You can also set the starting IP address for IP leases available to the LAN, and
change the number of PCs supported on the LAN. In the case above, addresses
192.168.0.2 through 192.168.0.9 can be used as hard-coded IP addresses with no
fear of IP address conflict with the DHCP pool. Configured WINS server addresses
can also be passed to CPEs behind the CMRG via DHCP.
16
SR808ac Cable Modem User Manual
5.2.3
DDNS
Choose Basic > DDNS , and the following page appears.
Figure 11 DDNS setup
This page is used to configure DDNS. Dynamic DNS (DDNS) allows a dynamic IP
address to be aliased to a static, pre-defined host name so that the host can be
easily contacted by other hosts on the internet even if its IP address changes.
The CMRG supports a dynamic DNS client compatible with the Dynamic DNS
service (http://www.dyndns.com/).
To activate the DDNS client:
1. Go to the DynDNS website and create an account for the Dynamic DNS service.
You will create a username and password, and be asked to choose a host name for
your server, and the dynamic DNS domain to which your host will be assigned.
You will also be asked for your host’s current IP address. This is the WAN IP
address that has been assigned to your CMRG during provisioning. (See WAN IP
Address on the Basic / Setup web page.)
2. Enter your account information on the Basic / DDNS web page, enable the
service by selecting www.DynDNS.org from the DDNS Service drop-down list, and
click Apply.
3. The DDNS client will notify the DDNS service whenever the WAN IP address
changes so that your chosen host name will be resolved properly by inquiring hosts.
The current status of the service is shown at the bottom of the DDNS web page.

5.2.4
Backup
Choose Basic > Backup, and the following page appears.
Figure 12 Backup setup
In this page, you can save the current CMRG configuration settings to a local PC.
You can then later restore these settings if you need restore a particular
configuration, or to recover from changes you may have made that have had an
undesirable effect.
To backup the current configuration, click Backup and follow the prompts.
To restore a previous configuration, click Browse and use the navigation window to
locate the file.
(Usually

5.3.1
Options
Choose Advanced > Options to display the following page.
19
SR808ac Cable Modem User Manual
Figure 14 Options configuration
This page allows you to configure the accessible features.
To enable a feature, click the appropriate check box until it is “checked”. When you
are satisfied with your selections, click on the Apply button. These features can be
modified on the fly without a system reset.
“WAN Blocking” prevents the CMRG or the PCs behind it from being visible to the
WAN. For instance, pings to the CMRG’s WAN IP address or the PCs behind it are
not returned. Therefore, it will be more difficult for hacker to discover your WAN IP
address to begin an attack on your private LAN.
“IpSec” and “PPTP” (Point-to-Point Tunneling Protocol) pass-through modes enable
these protocols to be used through the CMRG such that a VPN device (or software)
may communicate properly with the WAN.
20
SR808ac Cable Modem User Manual
“ Remote Configuration Management” allows the CMRG to be administered
(configured) from the WAN via surfing to the WAN IP address on port 8080 of the
CMRG from anywhere on the Internet (e.g. at the browser URL window enter
http://WanIPAddress:8080/ to access the CMRG remotely).
“ Multicast Enable” allows multicast specific traffic (denoted by a multicast specific
address) to be passed to and from the PC’s on the private network behind the CMRG.
“UPnP Enable” enables the UPnP agent in the CMRG. If you are running a CPE
application that requires UPnP, check this box.
5.3.2
IP Filtering
Choose Advanced > IP Filtering to display the following page.
Figure 15 IP Filtering configuration
This page allows you to configure the CMRG to prevent local PCs from getting
access to the WAN by specifying those IP addresses that should be filtered.
By entering starting and ending IP address ranges, you can configure which local
PCs are denied access to the WAN. Note that you only need to enter the LSB
(Least-significant byte) of the IP address; the upper bytes of the IP address are set
automatically from the CMRG IP address. To activate the IP address filter, you must
21
SR808ac Cable Modem User Manual
also check the “enable” box and click apply. The enable box allows you to store filter
settings commonly used but not have them active.
5.3.3
MAC Filtering
Choose Advanced > MAC Filtering to display the following page.
Figure 16 MAC filtering configuration
This page is used to prevent PCs from sending outgoing TCP/UDP traffic to the WAN
via their MAC address
This is useful for the fact that the MAC address of a specific NIC card never changes,
unlike its IP address which can be assigned via DHCP server or hard-coded to
various addresses over time.
5.3.4
Port Filtering
Choose Advanced > Port Filtering to display the following page.
22
SR808ac Cable Modem User Manual
Figure 17 Port Filtering configuration
This page is used to prevent PCs from sending outgoing TCP/UDP traffic to the WAN
on specific IP port numbers.
By specifying a starting and ending port range, you may determine what TCP/UDP
traffic is allowed out to the WAN on a per-port basis. Note the specified port ranges
are blocked for ALL PCs and this setting is not IP address or MAC address specific.
For instance, if you would like to block all PCs on the private LAN from accessing
HTTP sites (or “web surfing”), you would set the “Start Port” to 80, the “End Port” to
80, the “Protocol” to TCP, check the “Enabled” box, and click Apply.
5.3.5
Forwarding
Choose Advanced> Forwarding to display the following page.
23
SR808ac Cable Modem User Manual
Figure 18 Forwarding
This allows for incoming requests on specific port numbers to reach web servers,
FTP servers, mail servers, etc. so they can be accessible from the public internet. A
table of commonly used port numbers is also provided.
Forwarding allows you to run a publicly accessible server on the LAN by specifying
the mapping of TCP/UDP ports to a local PC
To specify a mapping, you must enter the range of port numbers that should be
forwarded locally, and the IP address to which traffic to those ports should be sent.
If only a single port specification is desired, enter the same port number in the “start”
and “end” locations for that IP address. A table of commonly used Port numbers is
supplied on the page for convenience.
If both external and Local/internal port numbers are present, the Local port number is
a mandatory field and the external port number is optional. If the external port
number is used, the RG will perform a translation from external port number to
internal port number.
5.3.6
Port Triggers
Choose Advanced > Port Triggers to display the following page.
24
SR808ac Cable Modem User Manual
Figure 19 Port Triggers
Port Triggers are similar to Port Forwarding except that they are not static ports held
open all the time. When the CMRG detects outgoing data on a specific IP port
number set in the “Trigger Range”, the resulting ports set in the “Target Range” are
opened for incoming (or sometimes referred to as bi-directional ports) data. If no
outgoing traffic is detected on the “Trigger Range” ports for 10 minutes, the “Target
Range” ports will close. This is a safer method for opening specific ports for special
applications (e.g. video conferencing programs, interactive gaming, file transfer in
chat programs, etc.) because they are dynamically triggered and not held open
constantly or erroneously left open via the router administrator and exposed for
potential hackers to discover.
5.3.7
DMZ Host
Choose Advanced > DMZ Host to display the following page.
25
SR808ac Cable Modem User Manual
DMZ (De-militarized Zone) hosting (also commonly referred to as “Exposed Host”)
allows you to specify the “default” recipient of WAN traffic that NAT is unable to
translate to a known local PC. This can also be described as a computer or small
sub-network that sits between the trusted internal private LAN, and the untrusted
public Internet.
You may configure one PC to be the DMZ host. This setting is generally used for
PC’s using “problem” applications that use random port numbers and do not function
correctly with specific port triggers or port forwarding setups mentioned earlier. If a
specific PC is set as a DMZ Host, remember to set this back to “0” when finished with
the needed application, since this PC will be effectively exposed to the public Internet,
though still protected from Denial of Service (DoS) attacks via the Firewall.
5.3.8
RIP Setup
Choose Advanced > RIP Setup to display the following page.
26
SR808ac Cable Modem User Manual
RIP (Router Information Protocol) is used in WAN networks to identify and use the
best known and quickest route to given destination addresses to help reduce network
congestion and delays.
NOTE: RIP messaging will only be sent upstream when running in Static IP
Addressing mode on the Basic – Setup page. You must enable Static IP Addressing
and the set the Wan IP network information! RIP is normally a function that is tightly
controlled via the ISP. RIP Authentication Keys and IDs are normally held as secret
information from the end user to prevent unauthorized RIP settings.
RIP is a protocol that requires negotiation from both sides of the network (i.e. CMRG
and CMTS). The ISP would normally set this up because of their knowledge of their
CMTS settings to match the configuration in the CMRG.
To enable the CMRG to perform RIP, do the following (this example uses BRCMV2 as
the RIP Authentication Key and 1 as the Key ID):
1.) To turn on RIP MD5 Authentication, check the “Enable” box.
2.) To specify a RIP MD5 Authentication Key String, type “BRCMV2” for this example.
key name = a string value to match CMTS key name value
3.) To specify a RIP MD5 Auth Key ID, type “1”
key number = a number to match the CMTS key number value
4.) To change the RIP annoucement interval, type in a number in seconds.reporting
interval by default = 30 seconds
5.) To specify a RIP unicast destination IP address, enter the IP address and subnet
mask.
To enable the CMTS for RIPv2 with MD-5 authentication (Cisco uBR example shown
below):
1.) The following steps go through configuring RIPv2 for a Cisco CMTS. The network
number used in this configuration will vary from network to network so use the
network number that matches your set-up.
7223#configure terminal
7223(config)#key chain ubr
7223(config-keychain)#key 1
7223(config-keychain-key)#key-str BRCMV2
7223(config-keychain-key)#exit
7223(config-keychain)#exit
7223(config)#router rip
7223(config-router)#ver 2
27
SR808ac Cable Modem User Manual
7223(config-router)#no validate-update
7223(config-router)#passive-interface cable 2/0
7223(config-router)#network 10.0.0.0
7223(config-router)#exit
7223(config)#inter cable 2/0
7223(config-if)#ip rip receive ver 2
7223(config-if)#ip rip authentication mode md5
7223(config-if)#ip rip authentication key-chain ubr
7223(config-if)#exit
7223(config)#exit
In this example, we have named the key chain ‘ubr’. This was chosen arbitrarily. You
can use any name you like as long as you specify the correct name when specifying
which key chain to use for RIPv2 authentication.
2.) The next step is enable RIP debugging to ensure that the CMTS is receiving and
authenticating messages from the residential gateway.
7223#debug ip rip
RIP protocol debugging is on
7223#term mon
The CMTS is now configured to accept RIPv2 messages. If the CMRG is registered
on the CMTS, you should see messages that are similar to the message below:
00:28:41: RIP: received packet with MD5 authentication
00:28:41: RIP: received v2 update from 10.24.81.148 on Cable2/0
00:28:41:
10.24.81.0/24 via 10.24.81.148 in 1 hops
The CMRG has broadcast that is connected to the network 10.24.81.0/24 through
the interface 10.24.81.148. This information is not very useful to the CMTS because it
already knows that the network 10.24.81.0/24 is connected directly to one of its
interfaces (Cable2/0). It ignores this message and doesn’t add any information to the
IP routing table. Here is the IP routing table after the CMTS has received RIPv2
messages:
7223#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

Output Power:
Control the range of the AP by adjusting the radio output power.
802.11 Band:
Select whether the radio operates in the 2.4 GHz or 5 GHz band. There may be
less interference from other wireless networks and household devices in the 5 GHz
band, but 802.11b/g devices will not be able to connect.
802.11 n-mode:
Switch this to Off to force the AP to operate in 802.11g mode.
802.11 N Support Required:
If the 802.11 N support required field is set to “on”, then only .n capable stations are
allowed to associate with the CM. If it’s set to “off” then b/g/n are all allowed.
Bandwidth:
802.11b/g channels are only 20 MHz wide, but 802.11n channels may be 40 MHz
wide. There are some backward compatibility issues with 40 MHz channels though.
These issues are more likely to be encountered in the 2.4 GHz band where legacy
(802.11b/g) devices may be operating using 20 MHz channels.
Sideband for Control Channel (40 MHz only):
Whether the 20 MHz control channel uses the upper or lower half of the 40 MHz
channel. Changes to this setting may change the control channel setting. For
example (in the 2.4 GHz band), if the upper 20 MHz is selected as the sideband for
the control channel, then the lowest control channel available would be channel 5
to allow the lower 20 MHz for data.
Control Channel:
Selects the control channel for AP operation. The list of available channels
depends on the selected country as presented in
Table 1. Next to the drop-down list box, the current channel number is displayed.

such as satellite or radar, and also transmission requirements in different parts of the
world.
TPC Mitigation (dB):
Transmit Power Control mitigation factor in dB. Transmit Power Control is used to
automatically reduce the transmission power when other networks are within range.
This setting is only used when the Regulatory Mode is set to 802.11h.
OBSS Coexistence:
Enable/Disable Overlapping BSS Coexisistence. OBSS coexistence refers to the
ability of the AP to support 20 MHz devices within 40 MHz channels. It also allows the
AP to better deal with nearby 20 MHz devices that are interfering with part of its 40
MHz channel.
STBC Tx:
STBC :Space Time Block Code. Switch to on will obtain the full antenna gain.
Scan Wireless AP’s:

which requires the use of a RADIUS server. WPA2 and WPA may be used at the
same time to provide backward compatibility with devices that do not support WPA2.
WPA2-PSK:
The Pre-Shared Key mode of WPA2, also known as WPA2 Personal. WPA2 and
WPA2-PSK cannot be used at the same time. WPA2-PSK and WPA-PSK may be
used at the same time to provide backward compatibility with devices that do not
support WPA2.
WPA/WPA2 Encryption:
When using any of the WPA authentication schemes, AES, or TKIP + AES encryption
modes can be set. AES provides the strongest encryption, while TKIP provides strong
encryption with improved backward compatibility. The TKIP + AES mode allows both
