ipfw on host and in vnet jail not working.

Running ipfw with userland NAT on the 12.1 host and can ping a public ip 
address and a fqdn with no problems.

But when I start a vnet jail using the bridge/epair method with no NAT 
on the ipfw running inside of the vnet jail using 2 simple stateless 
rules to let everything in and out. The same 2 pings as those that work 
on the host do not work from the vnet jail. If I comment out the 
ipfirewall statements in the vnet jails rc.conf thee the 2 pings work.

I sure would like to find out if this combo really works before I spend 
more time trying to debug this problem. If you have this working please 
let me know.

Thank you.
