OS is CentOS 5.4 Kernel is 2.6.18-164 Sometimes my firewall blocks the internet. When I inspect I have seen: - nat PREROUTING counters increase - filter FORWARD counters do not increase - nat POSTROUTING counters do not increase According to the diagram of Engelhardt, http://jengelh.medozas.de/images/nf-packet-flow.png, the problem should be in Bridging Decision point or acc.to former diagrams in Routing Decision point. I have tried to flush routing cache by "ip ro fl ca". Problem is recovered only after /etc/init.d/iptables stop / start I need further cues for deepen the problem, or exact reasons for updating/recompling to newer kernel/netfilter.
