Cannot reach LAN over Router

Dear All,

I have a Cisco831, which I configured at least 1000 times to be enabled to reach the LAN over internet. I used to setup PAT, and so on, but now I have the following: No matter what I'm setting up in PAT, or anywhere, when I try to reach my Server over internet, the router asks me for its own password.

Anyone can help?

Re: Cannot reach LAN over Router

I figured out, the problem may be, that I use 2 NIC's, with different subnets. One is for the "external", one is for the "internal" lan. I cannot ping my server from the router. Can this cause the problem?

(I send you the config later) Thanks for the answer.

Re: Cannot reach LAN over Router

A router connected to a server which has a different subnet mask are actually two ports in different networks. In order to connect two different networks, you need some form of routing, and since this is a single link no routing is available. Try putting bot the router and server in the same subnet and you should have no problems.
