Tiger Server And Winxp Vpn


I have never been able to successfully complete a VPN connection with our Mac OSX Tiger server and my WinXP laptop.

When I go to logon from the WinXP machine everything works fine and I seem to connect. However when I search the network I can't get anywhere.

When I look at the connection, I see that I am sending data to the Mac server, but I am hardly receiving anything back.

My assigned ip (DHCP) looks good.

What to I have to do so I can VPN into my server from home?
