Hi

I am hoping this is the right forum for my question

I am running 4.7-STABLE as of 18th Jan 2003, usinf ipf/ipnat for firewall, 
during normal loads (ipnat -l showing about 1000 connections) everything 
works fine, but during higher loads ipnat -l showing over 3000 conns, the 
firewalls get into a state where they drop connections, and users fall off 
IRC, web pages gets connection refused messages and mailservers start to have 
timeout problems.

I have recompiled the kernel with LARGE_NAT defined that did not help, I have 
changed the values in ip_state.h as per darrens suggestions on the web, this 
does not help, I have changed tcp idle timers using sysctl to try and tear 
down connections faster but none of this helps.

Anyone have any ideas?

Please reply direct to my email as I am not subscribed to this list normally
