DGFV338 ProSafe Wireless ADSL Modem VPN Firewall Router Reference Manual

7-14

LAN Configuration

v1.0, May 2008

•

None

 – The DGFV338 neither broadcasts its route table nor does it accept any RIP 

packets from other routers. This effectively disables RIP.

•

Both 

– The DGFV338 broadcasts its routing table and also processes RIP information 

received from other routers. 

•

Out Only

 – The DGFV338 broadcasts its routing table periodically but does not accept 

RIP information from other routers. 

•

In Only

 – The DGFV338 accepts RIP information from other routers, but does not 

broadcast its routing table.

3.

From the 

RIP Version 

pull-down menu, select the version:

•

RIP-1

 – A classful routing that does not include subnet information. This is the most 

commonly supported version. 

•

RIP-2 – 

Supports subnet information. Both RIP-2B and RIP-2M send the routing data in 

RIP-2 format: 

–

RIP-2B

 Sends the routing data in RIP-2 format and uses subnet broadcasting. 

–

RIP-2M

 Sends the routing data in RIP-2 format and uses multicasting. 

4. Authentication for RIP2B/2M required? 

If you selected RIP-2B or RIP-2M, you can 

optionally check the 

Yes 

radio button to enable the authentication feature. Input the 

First Key 

Parameters 

and 

Second Key Parameters 

MD-5 keys to authenticate between routers.

5.

Click 

Save 

to save your settings.

Static Route Example

For example, you may require a static route if:

•

Your primary Internet access is through a cable modem to an ISP.

•

You have an ISDN router on your home network for connecting to the company where you are 
employed. This router’s address on your LAN is 192.168.1.100.

•

Your company’s network is 172.16.0.0.

When you first configured your DGFV338, two implicit static routes were created. A default route 
was created with your ISP as the gateway, and a second static route was created to your local 
network for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on 
the 172.16.0.0 network, your DGFV338 will forward your request to the ISP. The ISP forwards 
your request to the company where you are employed, and the request will likely be denied by the 
company’s firewall.
