Hi,

I've been running RH 7.2 with a kernel-2.4.9-13brnf0.0.3 for a very long time 
and works just fine.

A couple of weeks ago I thought I'd install a new fresh installation with rh9 
and load the bridge module that comes with the rh kernel ( 2.4.20-24.9 ).

The bridge itself works just fine but the firewalling dont.
There is no packets passing the FORWARD chain... Have I missed something really 
essential here?
The same iptable script works just fine on the old box...

Thanks in advance
