   I am pretty sure that I have connected to pptp server from behind a   
   firewall before. I am no expert on PPTP, but I beleive it uses a   
   combination of the ip protocol gre and a tcp port for its communication.   
   What firewall is on your lan? Does it support connection tracking for pptp?
