Thanks a lot for the info. I guess I should have been a bit more 
explicit: I want to be able to assign firewall rules to these separate 
jails. I don't think I can assign rules based on address but have to 
have some sort of interface. For example, port 80 will be open on two 
jails, but one should have rate limiting applied to it.
