[erlang-questions] how to connect erlang nodes through an uncontrolled firewall

[Ivan Uemlianin]

Dear All

I'd like to connect a couple of erlang nodes together, one "here", one 
on a remote machine.  There are two firewalls in the way: one on the 
remote machine, one local.

The remote firewall I can ask for ports to be opened.  I've read that 
4369 for epmd and one other port are required (the second can be 
assigned at runtime using sth like

     erl  -name qweasd  -kernel inet_dist_listen_min 9001 
inet_dist_listen_max 9001 [1]

).

The local firewall is fixed, in the sense that I don't think I can ask 
for ports to be opened and so on (I'm in a shared office building with 
provided internet access).

Is there anything I can do at this end to open a connection?  I can ssh 
out the the remote machine.  Can I have the nodes connect over ssh?

With thanks and best wishes

Ivan
