Hi,

I have a DFL-500 firewall from D-link and just managed to set up a VPN connection with PPTP. The connection was made from an external computer with Win2000 on it. I managed to connect and loggin. The status says that the connection is made. When I ping to a computer that is located on the inside of the firewall, it is succesfull. But now I'm trying to see any shared folders but I cannot seem to find them nor the computer. Can anyone help?

do you have a pool of addresses on the network subnet for assignment to VPN clients? A VPN connection in is the same as being connected directly to the network. If the VPN client is not on the same subnet they won't be able to see and access shares.

are you using RRAS in Windows to make the VPN connection? if so RRAS has an option for providing inbound remote access clients with an IP address [on the LAN].

The subnets are not the same. The subnet on the external interface of the firewall has 255.255.255.xxx with xxx not zero.
The subnet on the internal interface has 255.255.255.0 as subnet. The internal interface has a dhcp server. Not that it minds

I don't know what RRAS is, but I set up a connection by just making a new network connection and chose the option to make a VPN connection. Then you can chose if you will use PPTP or L2TP.
