Right now there isn't a port number setting to do that. It's a feature yet to be implemented.
So, if I somehow I forwarded port router:8333 to bitcoinhost1:8333 and router:8334 to bitcoinhost2:8333, we get undefined behavior?
Because that seems like trivial to me, to keep track of port numbers in any p2p app.
Sorry about that, must've been drunk when I wrote that.
