We are having difficulty with VPN clients accessing a VPN server running on an internal LAN address behind a D-Link DSL-504 ADSL router. The VPN server runs on an NTServer machine with a fixed private IP address. The client machine
I am testing on runs Win98se. We have a fixed public WAN address 'attached' externally to the router. This address is used as the 'dial-in' number for the VPN client.
The Win98se machine can connect (and browse the LAN) if the VPN server's address is placed in the router's DMZ zone.
D-Link have since sent us their latest (beta version) firmware upgrade which they say should allow VPN client pass-through. I have had no luck configuring this firmware to allow VPN client connectivity and had no response from D-Link as yet.
As far as I'm aware, throughput of the PPTP and GRE protocols + TCP port 1723 should be
opened, and this should be sufficient to allow access.
