I have a Microsoft 2003sp2 Standard RRAS server. My network is designed such that I have a subnet 192.168.2.0/24 where my DNS server is. My home users in some cases have their LAN with 192.168.2.0/24. Once these users who have their home LAN on the 192.168.2.0/24 subnet connect to the VPN they can go anywhere EXCEPT to 192.168.2.0/24 subnet. As for all the other users whose home network has a number other than 192.168.2.0/24, they have no problems connecting.
In a few cases, I've changed the user's home network from 192.168.2.0 /24to 192.168.0.0/24. Once the change has been made they have no problem seeing my 192.168.2.0/24 subnet.
All opinions appreciated.
