im using tomato raf's openvpn server to play games with friends and for some reason when i setup the server as udp over tcp the vpn connection lags out every so often and our games get disrupted, and if i use tcp over tcp the latency is slightly higher, but the connection never lags out and we can play for hours without any disconnects. i was under the impression that udp was the more efficient protocol to use. can anyone explain to me why this is happening? could there be something wrong with my settings? thanks.
