Implement an option to request a static address and port

[BnDLett]

Rather than the address and port changing every time you load the program, have it so that the program is capable of keeping the same address and port that it last used.

A possible implementation of this is to have the program request a address and port: if the address and port are both open, then the program will tunnel through them -- however, if either of the addresses or ports are not available, then tunnel the client's connection through a randomized address and/or port (depending on which one isn't available).

Mostly for the sake of making it easier to use an external domain name.
