There are some issues... seems like inside a jail I can't ping systems  
outside of the hardware.

Bridge setup:
     - member jail A
     - member jail B
     - member external_if of host

If I ping the router from the host, it works. If I ping from one jail  
to another, it works. If I ping from the jail to the IP of the  
external_if, it works. If I ping from a jail to the router, I do not  
get a response.

Bye,
Alexander.
