On most setups, UDP will be somewhat faster and more robust on congested networks. In some cases however, TCP could be faster if the path MTU would force UDP to excessively fragment. The only way to know definitively is to benchmark. Overall, UDP would always be my first choice. TCP is really provided as a backup for cases where UDP isn't a viable option. > A Friend of me wants to make a VPN with XP to my linux-router. > > If we use UDP HE and my router must open UDP 5000 for Inet. > If we use TCP, only I(my router) must open TCP 5000 for Inet. Actually with UDP, you usually don't need to open any firewall ports. That's because both peers actively initiate the connection, so the statefullness of the firewall allows return packets without an explicit firewall rule. > Should I use TCP or UDP?? > > We want to play network games throug VPN,... UDP will give you better latency which is key for gaming.
