Note that using TCP on top of TCP can cause certain problems, especially when packets are lost. There's a good explanation on this page: http://sites.inka.de/sites/bigred/devel/tcp-tcp.html The short story is: If any packets are lost, the resend-algorithms of the two TCP layers will start to interfere with each other, because both have their own timeouts and will start retransmitting packets at their respective levels. This is bad, because it leads to a snowball effect. If you can guarantee that there will be zero packet loss, then TCP is fine. Otherwise I recommend to run the VPN on UDP.
