Hi Jan, Thank you for you fast reply. I'm using Gatekeeper Version(2.3.1) and yes you're right. Setting the Home= to both the internal and external IP-address of the gatekeeper solved this. Thanks again! GJ Hi, what exact GnuGk version are you using ? I think your are looking at a different problem: In Gnugk 2.3.1 the order in which GnuGk looks at the available network interfaces changed, and it would sometimes pick a loopback interface for outgoing traffic. Did you try to add a Home=... setting ?
