I am using mIRC 6.16.
I am in a LAN and behind a router to access the internet.
I am able to make mIRC use the correct IP for Dcc-Send with /localinfo <ip>, but it does not use the specified ports.
I think that's all I can say.
Oh wait!
mIRC is using random ports when the specified ports are not free ($portfree(..) is false).
Somehow those ports aren't free anymore here, and that's whay mIRC is using random ports
My fault, sorry.
Thanks anyway,
