I agree, you didn't provide enough specifics.
- I assume neither side is using Dialup or DSL (PPPoE)
- Also, did you create static routes for the other subnet in your RRAS config, and vice versa at the other end?
.

i dont need to access network beyond VP.
I need to get VPN connection and LAN connection.
servers should communicate through VPN and LAN should communicate only to its server.
the problem here is when ever i connect the VPN
LAN is disconnected.

Tuesday, April 10, 2012 12:16 PM You still need to provide what kind of VPN before anyone can help you. Is it based on a router, client, software? Give make/model/version,etc... It sounds like your VPN, whatever it may be, is preventing local LAN access while it is active, like most VPNs do by default.

Hi,
Yes, you need tell us what method you are using to establish the VPN connection. Did you install RRAS role on your server? After the VPN establish, the LAN disconnection issue appear on both side? For this issue, it can be a route problem. Please check the route table after established VPN connection, and run tracert or pathping to test the packet route on the server side is correct.

I know this is a little late, but after re-reading this, I believe what's going on is similar to another recent thread:
