Network problem

[Sebastian Schucht <gehjetzt_(_at_)_gmx_(_dot_)_de>]

Hallo,

I have an Problem end no Idea for a Solution. I use an OpenBSD cerberos.chaos 
3.5 GENERIC#0 i386 System as an Gateway and if I am ping from the Net to this 
Gateway I Have good pingtimes of:

10 packets transmitted, 10 received, 0% packet loss, time 9014ms
rtt min/avg/max/mdev = 0.171/0.206/0.430/0.077 ms

but if I ping back to my linux box I have bad pingtimes of:

10 packets transmitted, 10 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 0.335/3.925/7.437/2.378 ms

I can see this behavior on all connections and interfaces. It also occurs if I 
shut down packetfiltering. And also all routes looking fine.

Have anyone an Idea why this behavior happens?

Thank you for your help!
