The problem is when you bridge this epair with physical interface (say, 
igb1) and try to send from epair's vlan interface to igb1's vlan. It's 
hard to test it on host without jails, you need to put one of epair 
interface to jail as VNET interface, and then try to ping from jail's 
vlan interface host's vlan interface - ping will not pass.

But strange thing - one jail can ping another jail in the same vlan, but 
they're can't ping host and host can't ping jails.
