141Enable the UDPv4 transport using the C<udp-port> port
142(default: C<yes>). This is a good general choice since UDP tunnels well
143through many firewalls.

146
147Enable the RAW IPv4 transport using the C<ip-proto> protocol
148(default: C<no>). This is the best choice, since the overhead per packet
149is only 38 bytes, as opposed to UDP's 58 (or TCP's 60+).

269
270Enable the TCPv4 transport using the C<tcp-port> port
271(default: C<no>). Support for this horribly unsuitable protocol is only
272available when vpe was compiled using the C<--enable-tcp> option. Never
273use this transport unless you really must, it is horribly ineffiecent and
274resource-intensive compared to the other transports.
