First, did you compile a new kernel with the following option?:

Second, try giving both PC's a static IP address, and disconnect the

network), then commence testing.

Thanks for the reply
I didn't recompile a kernel specifically for this. I thought the bridge was a
KLD (/boot/kernel/if_bridge.ko)? ifconfig shows the bridge as running.

So if I disconnect alfie, fred will lose connectivity too.
Hopefully this clears up what I meant...

I wanted to access the W2k machine (fred) over VNC without flooding our switch, so I thought let's take advantage of the new features in REL 6... I added a second ethernet card to my FreeBSD box (alfie) and configured a bridge in /etc/rc.conf: ifconfig_rl0=DHCP ifconfig_rl1=up cloned_interfaces=bridge0 ifconfig_bridge0=addm rl0 addm rl1 up gateway_enable=YES SBS is configured to give a static DHCP lease of 192.168.0.181 to alfie; fred is dynamic and is currently 192.168.0.35. At first everything seemed fine, and fred operates as if it was plugged straight into the network. But... 1) SBS sees both machines as alfie, even though it correctly reports the MAC addresses of each machine 2) On alfie, when I want to make a VNC connection to fred I have to type vnc viewer alfie(!) 3) On fred, if I ping alfie it returns 192.168.0.35 as the IP number, not 181 which is the static lease. I assume this is a bug in if_bridge, only because I assumed that bridge interfaces should be transparent (and act like a physical switch). When we get some small switches in I'll use one to connect the two machines together, but I'd still like to work out what's going on here. Am I doing something wrong?
