Hi !

I have a firewall on Dell 1850 (3353540k of RAM) with:

- vanilla kernel: 2.4.31 with openwall patches - version 1 and pptp.
- iptables 1.3.3
- patch-o-matic-ng-20050904

Errors in /var/log/messages occurs when users (approx. 320) use internet
and dmz connection.

Clients can see timeouts to our lotus domino server during refresh
proccess - rest of the traffic is not slowed down,
i mean they did not said anything about, for example, about http traffic.

Any ideas what can be broken ?

I have also attached .config file
