Hi,
bis auf die UserID, wo ich nur den User ohne domain eingetragen hatte, war alles so, wie von dir beschrieben.
Ich habe es nun umgestellt... jedoch wird die Verbindung trotzdem unterbrochen.

gateway:~# tcpdump -i eth0 host 10.4.4.193
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
