odd "routing" behavior

[Fred Portnoy]

hello

we are running our freebsd-ipfw in bridging mode ... we have recently added some stateful rules for particular subnets ... i am noticing that at times packets are showing up on the sniffer (sniffing "inside" of the firewall) with the mac address of the firewall nic where they should have one of two routers' addresses in it depending upon the direction of travel .... can anyone shed light on this behavior? 5.4-RELEASE.

thanks
