DI-804HV VPN Router and XPsp2 can't ping internal IP

[ferrelljohntn]

Hi all,

I have a client with a DLink DI-804HV VPN Router. They need to connect
with PPTP using the Windows XP "Network Connections". I am able to
connect to the VPN with no problem. Their IP structure is 192.168.2.x
subnet is 255.255.255.0 and DHCP is turned on with a range of
192.168.2.2 - 254

If I have a user from the PC #1 with 192.168.2.100 ping the PC #2 with
192.168.2.200 then he gets replies with no problem. If I ping him PC #1
(192.168.2.100) I get a reply through the VPN. If I ping PC #2
(192.168.2.200) I get no reply.

So, I had him take the PC #2 192.168.2.200 out of the network (unplug
the ethernet) and manually change his IP PC#1 to 192.168.2.200 I cannot
ping him. If he changes his IP to anything other than the one DHCP
gives him I can't ping him.

The only option I can find for the PPTP server settings in the DI-804HV
is "Virtual IP of PPTP Server" which I have tried changing to
192.168.5.x and 10.0.0.x with no luck on either.

I called DLink and they said if you can ping a PC through the VPN it's
working and is not their problem! Any help is greatly appreciated.
