This looks like a very interesting implementation and I look forward to trying it. My question: ALL of my network and systems live behind a firewall. I can open various port or do port redirects so what ports are you using? Can I do a redirect?
My firewall uses NAT so any message out contains whatever address my provider gives me. That, of course changes day-to-day. What do I need to do about this?
I would appreciate a little (admittedly very technical) advice about the above.
