Yes, you're right concerning the man-page. But that was not the reason 
for my problems. I changed the cluster-IDs but nothing has changed.

As I've mentioned before, I have no problems concerning bridging. With 
'sh /etc/rc.firewall open', all networking is up 'n running. Therefor I 
think that ipfw (or myself) has problems. But I don't think that I've 
made a larger mistake - 'allow icmp any to any' should make pinging 
work, don't it?

Yes, I checked it again, fxp0 and fxp1 *are* in promiscous mode. Seems 
to be automagic because of the bridging - I did no 'ifconfig' to set 
the interfaces explicitly into promiscous mode but they are...

Anyway - thanks a lot!

I'm trying to check this ipfw behaviour with another bridging machine 
with FreeBSD 4.9-STABLE and ipfw1 next week - perhaps there is any 
difference, perhaps even not...
