Hi Jason!!! Thank you for your prompt answer!!! This solved the "No external IP...."-problem! But the NNTP-Server is still unreachable from outside. I have created the server publishing rule with the correct external ip and the correct internal ip. the nntp-server is reachable from the local network. so i am sure that it is running correctly. i have also created a ip-filter (port 119 in and outgoing tcp)... please help!!! ;-))) -timo-
