Description

Currently mosh client does not support UDP proxies preventing to use it from some corporate networks. It also does not support using a different port when reconnection to a server which may be required when switching between internal and external network.

All this can be addressed if the mosh-client to reconnect could use an external program that opens UDP connection to the server and passes the resulting socket back to moch-client. Then such proxy can implement port change, connecting via SOCKS5 proxy etc.

This will be similar to the ProxyUseFdpass option to ssh, http://www.gossamer-threads.com/lists/openssh/dev/56016#56016

Research direction

Begin by locating mosh-client's UDP connection and reconnection handling, then compare the requested socket-passing behavior with OpenSSH's ProxyUseFdpass option. Done means defining and implementing a supported external-program interface that enables proxying and port changes during both initial connection and reconnection.
