-**Deal with NAT**
-
-The 1.0 branch by default tries to exchange packets via UDP.
-However, if one or more peers are behind a NAT, and source ports
-might be changed or packets may not arrive at all, the
-administrator had to manually enable the TCPOnly option or use
-another workaround to get tinc to work. Tinc should be able to cope
-with altered source ports, and should detect whether or not packet
-exchange via UDP works at all, and if not fall back to TCP.
