I have an internet connection the following way : Internet Modem <-> FireWall(not a router, a firewall) <-> PC
Everything is setup so my pc has an external ip address, and my firewall takes care of blocking bad stuff.
I connect by VPN to an external network, so I added a new connection using Windows Xp's "New connection wizard" (the vpn client that comes with Windows XP), it's a PPTP connection so I used all default settings. I put the PPTP server's IP, my username and password and I succesfully connected. I was able to have access to the external VPN ressources.
The only problem is everytime I connect to this VPN, my computer cannot connect to the web anymore, no msn, no ping, no web.
Is there anything special I should be doing?
