Which ports does distributed Erlang use?

Outch, ooohhh nasty.
My netgear box has a load of "filter rules" one per open port.
Opening a port is no mean feat and involves a lot of squiggeling
around in a lot of incomprehensible menus. It also likes fixed ports.
Has anybody hacked the erlang distribution kernal to use ONE fixed
port.
I can imagine proxying through epmd (or something) - alternatively
in the (common) case that I only fire up one distributed erlang then
I'd like this to be on a fixed port.
Has anybody got distributed Erlang running behind an RT314 and
talking to erlangs in the big wide world???
