OK, i looked for so many reasons, and theres quite a good chance that we have a MTU-Problem.
I try to explain my idea:
My system does not reconnect, when my services hard on duty. All local funktions like nat, masq and so on put a few bytes 4 headers to the packets - if i got packets with 1492 - it's possible that theres not enough space for additional information. So i will check it out with smaller packets, at first 1412... and enlarge them every day a lil' bit if it works... Lets see what happens.
If I'am totally wrong - let me know... Try and error is a hard way, but a good teacher [;)]

Hm. I guess i'am wrong... more than 1 3com nic might be the problem...
Don't thing it's Dyndns because i turned of Dyndns and the Problem still occures. But the other Point is very interesting, the 3COM Nics... I have two of them. Thank god it's sunday and there must be two Intel-Nics in my room... i'l try reinstalling.
