From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98) Description of problem: Hi Bugzilla, I have just upgrated the kernel in my gateway from kernel-2.4.18-27.7 to kernel-2.4.20-27.7 release and I am having problems with established connections handled by iptables. I am having problems with ssh and telnet sessions estabished from my LAN with external hosts since I have updated the kernel. It worked fine with kernel kernel-2.4.18-27.7 but since the last update established connections are closed in a period of time. Any ideas ??? Version-Release number of selected component (if applicable): iptables-1.2.8-8.72.3, kernel-2.4.20-27.7 How reproducible: Always Steps to Reproduce: 1. kernel-2.4.20-27.7 2. iptables-1.2.8-8.72.3 3. allow outgoing packets (ports ssh /telnet) from LAN to any external host 4. allow incoming packets from related connections 5. establish any ssh / telnet session to a remote host 6. in a preiod of time the session is closed Additional info:
Please verify this with a newer version of Red Hat Enterprise Linux or Fedora Core and reopen it against the new version if it still occurs. Closing as "not a bug" for now.
