hi,
after most parts works with my bridge setups works, I want to get vnet for my
jails working. In the morning I started a jail and got only the local interface
back, but no epair0b. Now I did something so that I can see _all_ interfaces
from outside (bridge0 / bge* / epair0* ... ) but without any IPs.
However, I'm not able to give epair0b inside the jail an ip address. I get
"permission denied".
Also it looks a bit strange:

Also, some people say, I have to patch /etc/rc.d/jail (freeBSD 9-rc2) to get
know the new "vnet2", other say, I don't need ... so ....
Can anybody bring some light into the darkness of jails and vnet + rc?
