I'm having a problem with a VPN connection that was working fine a couple of days ago. I'm using a 3com VPN Firewall that is setup as a PPTP VPN server to allow remote users to log in.
This is the problem: the users can connect to the VPN without any problems but they cannot reach anything on the remote network. The logs show that the remote clients get an IP address on my network. I cannot ping that IP address while they are connected. The remote clients cannot ping anything on my network by IP address. Everything was working fine a couple of days ago. Nothing that I know of was changed on either side of the connection. They are connecting fine, just can't reach anything. I tried completly disabling the firewall, deleting and then readding the login names - no luck.
Please help. What could be the problem?
