ok, here's an update on the situation:

If you DO NOT check the "Set Local IP" box, it is supposed to display your WAN IP in greyed out form and force it AUTOMATICALLY.

However, there seems to be a bug which prevents this feature to work in conjunction with a forced port.

When I use a Random port along with a DMZ on my router (ie forward all ports to my PC), I get Inbound connections immediately.

But when I want to force the port to 6346, and only forward THIS port through the router, I rarely get Inbound connections. This "rarely" would indicate that Gnucleus uses Random ports even when told to used a forced one when the IP is left to automatic remote detection.

Furthermore, manually forcing the same (and correct) IP displayed in the grey field doesn't work either. This behaviour is *definitely* different from 1.6.1, where a complete manual force of both IP and port *did* work.

Can anyone confirm/deny that? Is this even the right forum for this kind of technical stuff, seeing how little traffic there is?
