It is possible. I've never actually tried it, but it seems simple enough.
When compiling using CMake and if you're on a unix system, you should get a "traversal_server" binary. It doesn't accept any command line options and listens on every network interface on UDP port 6262.
(Tip: You don't need to compile everything, just run `cmake --build . --target traversal_server` (while in the Build folder) after generating to just to build the server binary)
In the dolphin side of things, you just need to add "TraversalServer" in the section [NetPlay] in the Dolphin.ini file, which contains the host name of the server. The config for the port is "TraversalPort", but since the server is hardcoded to 6262, there is most likely no need to change.
