SuSEfirewall2 as bridging firewall

Good Morning list, I have following problem: I have been unable to set up a working SuSEfirewall2 on a bridge running on a SuSE 9.0 system using kernel 2.6.1 (also tried the supplied 2.6.0-test-5, but didn't change anything). The bridge is working fine, the firewall loads and runs without errors, I can see logs that make quite sense. Only what doesn't work is the forwarding. No matter from where I try to forward where I receive a message like: SuSEfirewall ILLEGAL-ROUTING phsyindev=eth0 physoutdev=eth1 .... So my question: is it possible to get this setup working at all? Any comments appreciated. Thanx in advance, Christian internal net ---- bridge ---- router ---- external net
