If you had to forward TCP port 22 on a NAT for SSH, then you will have to forward UDP ports as well. Mosh will use the first available UDP port, starting at 60001 and stopping at 60999. If you are only going to have a small handful of concurrent sessions on a server, then you can forward a smaller range of ports (e.g., 60000 to 60010).

Using multiple encryption methods, SSH secures the connection between a client and a server safeguarding the users’ commands, authentication, and output against unauthorized access and attacks. Wile doing research I noticed that SSH both uses TCP and UDP. I completely understand the use of TCP, but UDP seems a bit strange. Why would I use an "unreliable" transport protocol with minimal handshaking for secure shell access? The only use I can think of is for SCP, so (big) file transmission.
