This kernel is quite old. You really should upgrade the kernel...

I had similar problems with a very similar setup.
The problem is that when the bnep0 interface enters the bridge, the bridge's
"mac address" changes. You can see that happening doing a "ifconfig pan0" before
the bnep0 joining the bridge and after, to see the hardware address of the pan0
interface.
I tried to solve this by issuing "arping's" so that other machines on the
network would be warned about the new hardware address, but unfortunately never
got this to work properly... :(
It has been quite a while since i've tried this, though. So maybe in recent
versions the bridging layer doesn't change the hardware address anymore?
If you have better luck than me, please let me know.

I am not using SuSE, so I can't help here.

Marcel,
thanks, I tried this but couldnt get it to work at least with SuSEfirewall2,
activating NAT between the internal:pan0 (bridge) and external:eth0. ANy
other ways?
What I am trying to get to: as I use my linux-laptop online (DHCP on eth0 in
different networks) and offline (with th PDA/BT connection with apache etc.
running on the laptop) my plan was to have a default configuration which at
boot is overridden after DHCP on eth0 (or the bridge) has provided the laptop
with its network IP, gateway and so on.
As I said, new to all this stuff....
Tx again

I never put the eth0 into the bridge ;) You can use IP forwarding and
NAT between eth0 und pan0.
