I've seen many having problem about understanding how to use VPN when you got a vpn-connection through poptop, and so do I.

I can connect from home with Win XP Pro, through a Slackware 8.1 iptables GW using NAT, over internet to my Slackware server public connected to internet at office. And then, now what are I doing? Someone who feels that he is king of VPN could help many users solving out the funderations..

My office slackware server has ip 192.168.0.254 and my home server internal has 192.168.0.250 The XP computer has ip 192.168.0.1
Is that a problem, that both home and office nets are using 192.168.0.0 networks? My office server serves its internal network with Samba, but from home I can't connect to its services and neither ping it. If I at the XP computer check the box "Use default gateway at remote network" (raw translated from swedish) under TCP/IP propertis for the VPN connection, then I can ping the XP computer from the office server!! but not the other way. I can also list the XP computer shares using smbclient.

The Slackware server at office serves the office network also with internet connection, shared with iptables/NAT but I can't ping the internal computers nor the server from XP computer.
