I think I am doomed. This box gives me a lot of headache. When try to 
change the MTU with

ifconfig eth0 mtu 1472

I always get an error:

localhost kernel: eth0: Ilegal MTU value 1472,  rounding MTU to:
  1500

It does not matter what I set it will only accept 1500.

On the server the firewall is not even compiled into the kernel. 
Everywhere else it is off.
