VPN issue

[totalwar]

Any help welcome

WE have a VPN device on network A in the UK - remote home users in the UK and home users abroad can log in fine

However on 2 of our foreign networks (netwrok B and C) - after the login - they lose connection to their local resources in B and C - and also cannot access resources in A

It looks like some sort of firewall\ISA\proxy issue - do ports 1723 and 47 (for PPTP) needs to be open on the firewall in network B and C

Is there anything else I can check - it looks like DNS just stops working for the clients in network B and C - when they connect to A

Thanks guys

If you can establish the VPN, that is not port issue. It could be the routing table issue. Posting the routing table here may help.
