Hey,
I have the same issue and I'm glad that I'm not alone with those troubles...
I live in a shared-flat where I sometimes play some fancy CoH with my flat-mate.
As Gsus already mentioned, there is a way to forward CoH on a specific port, with the "-port" command added in a shortcut, so that I have a portrange for my CoH forwards, and my mate a portrange for his own forwarding when we share the internet behind the same gateway.
Since EF is started with a launcher, I guess there is no way to specify a port like in a shortcut ?
I hope you guys can help us out,
thx in advance
KT
