Bridging in 5.3 Beta not working

I can't seem to get bridging working on a new install
of 5.3 beta. I set up the system correctly as far as I
can tell(see info below). I gave one nic(em0) an ip
and can reach other machines(using ssh as the test).
If I move the ethernet cable from em0 to em1 I can't
get out to any machines. Perhaps this is not a valid
test (seems it should be). 
I must also mention that I did try both Nics plugged
in(between two switches) but no traffic was getting

below is the output of `sysctl' 031224 0 0 1 0 0 0 382 0 201 1 em0:0,em1:0

I have `options BRIDGE' compiled in the kernel, along
options         IPFIREWALL
options         IPFIREWALL_VERBOSE

I can send the entire kernel config if needed.

output from `ipfw show'
65000 722 74390 allow ip from any to any
65535   1   108 deny ip from any to any

Below is dmesg.boot.
