Hi,
I'm new here in this list.
My English is not so very well, but I try to explain my problem with
iptables:
I got a system with SuSE 8.0. It works as a router with an iptables script
between 2 static LANs. The Script does it very well, but sometimes it
happens that all connections from one LAN to the other are blocked suddenly.
/var/log/messages and /var/log/firewall shows the following:
fw kernel: eth0: Transmit timed out, status 00, resetting...
fw kernel: Rx ring c071a000: 00000000 00000000 00000000 00000000 ...
fw kernel: Tx ring c071b000: 80008001 80008005 80008009 8000800d
80008011 ...
and then:
fw kernel: PACKET DROPPED: .....
fw kernel: PACKET DROPPED: .....
fw kernel: PACKET DROPPED: .....
...
The error-message repeats periodically for a few seconds.
There are 2 same NICs in that system: D-Link DFE-550TX.
After rebooting the system, the firewall works fine again, 'cause the script
is loaded at booting the system.
Thx 4 help

This is not a problem with SuSE or iptables.
It looks like a problem with either the NIC driver or the NIC itself ...

The output below shows clearly shows that you are having system problems,
not iptables problems. In approximate order of probability:
1 - hardware problem in the NIC
If the driver was bad it would probably happen on both NICs.
If it does happen on both NICs skip this idea.
Can you swap NICs and see if the problem moves?
2 - driver problem
Unless there is a newer driver or kernel available, you may have
to change to another brand of NIC. Sorry.
3 - cable problem
I had a bad cable cause the connection to drop once in a while.
Check that all cables are firmly plugged in.
