Ok... You said you recompiled FC3 latest kernel, I assume it works
correctly. Have you tried FC4's kernel or the latest 2.6.12 from
kernel.org? I would prefer kernel.org's since I would only have to apply
patches from time to time. Do you think it works with FC2?

I had already come across that post but didn't find any solution...

The hosts all have static IPs.

Here is a little output from rtstat

As you can see in the last week it has doubled from 9000 to almost 19000.
