default gateway change

Hello all,

I have a Cisco 1841 and 1941. The 1841 will eventually be phased out of the LAN it is routing for. The 1941 we just switched all the users computers to it as the default gateway to Comcast's network. The 1841 has a WebVPN setup pointing to a windows 2003 server for RADIUS auth. When we changed the default gateway on the 2003 server to the 1941 router, it broke the WebVPN. The 1841 also goes out to Paetec's network, not Comcast. Any help would be greatly appreciated.

Re: default gateway change

You'll need to add a static route for the radius source (if specified in your 1841 config) pointed back to the 1841 on the 2003 server.  If no source is specified, you'll need to add a route to your 2003 server for the interface IP address that the 1841 is using to route to the 2003 server.

Re: default gateway change

Why would a need to add a route? The server and router are on the same network (10.1.9.0/24).

router interface - 10.1.9.1

server interface - 10.1.9.254

Re: default gateway change

That information wasn't part of the note you wrote originally.  Do you have a radius source specified in your router config?

Yes. Here it is:

radius-server host 10.1.9.254 auth-port 1645 acct-port 1646 key 12345

Re: default gateway change

I'm sorry, let me re-ask the question correctly. They clients successfully connect to the VPN but cannot access any resources on the 10.1.9.0/24 network.

Sorry it took me this long to get there. Adding the 10.3.1.0/24 (WebVPN pool) route to the server fixed the problem. Thanks!
