Question : XP pro to XP pro VPN Connects, but cannot ping or use internal network resources

I recently set up a office vpn using windows xp pro as the vpn server.  I set the dsl router to forward port 1723 to the vpn server, turned off xp firewall on the vpn server as well.  I can connect to the vpn server, get a ip address and authenticate on the network.  But once connection is established I cannot do anything else.  I cannot ping any internal ip addresses, see shares etc.  I have created a lmhosts file on the client machines, and tried to connect from multiple places.  The vpn server is a static ip.  It is a Bellsouth Business pppoe DSL connection, cayman 3000 series router..  Any ideas?? I have exhausted all the troubleshooting I can think of.  Thanks

Answer : XP pro to XP pro VPN Connects, but cannot ping or use internal network resources

I vpn into an XP pro, voer a different router, and here's what I had to do te enable me to see the whole network
1. enable IP forwarding on the xp vpn host

http://support.microsoft.com/default.aspx?scid=kb;en-us;315236&Product=winxp
Start Registry Editor (Regedit.exe).
2. In Registry Editor, locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. Set the following registry value:
Value Name: IPEnableRouter
Value type: REG_DWORD
Value Data: 1
A value of 1 enables TCP/IP forwarding for all network connections that are installed and used by this computer.  
4. Quit Registry Editor.
you may have to reboot

next I use 192.168.2.0 at home, and 192.168.1.0 at work
when I vpn I get an ip of 192.168.1.253 mask 255.255.255.0 on my vpn adapter
so I add a route with the route add
from a command prompt
I then can ping all the machines on the network, and in windows explorer I can access the other machines using the ip addresses
example
\\192.168.1.14
route add 192.168.1.0 mask 255.255.255.0 192.168.1.253
