This week I installed 2.6.17.x on my server. Unfortunalely this kernel seem to cause some network problems. Since I ran this one, I have problems conneting to lists.horde.org. Ping (aka ICMP) is working, but TCP (http and smtp) is not. I can reproduce the problem with my systems @ home (the one that ran 2.6.17.x). The systems with < 2.6.17 can connect with out a problem...

I'm pretty sure that Linux 2.6.17 is the problem. I have no problem connecting to the host with Win32 and Ubuntu 6.06. And some guyes from debianforum.de also can reproduce the problem with 2.6.17.x (but they also can connect with Linux < 2.6.17).

Does someone of you guyes have an advice for me?
