You can't have two interfaces within the same IP subnet, with the same
mask, on one box. What you can do is configure the primary interface
with the /24 mask, and then configure the other interface with a /32
mask. This is the same process that you would use to put two (or more)
addresses from the same IP subnet on a single interface.
Regarding the other stuff, if a particular service is configured to
listen on any interface (noted by the "*.*" under "Local Address" in a
netstat listing), then it should be available via either interface of
the bridge, assuming that the bridge is configured correctly (sysctl's
and such).
What are your /etc/rc.conf settings with regards to the bridge
configuration?
