Thanks! I only need one jail per VLAN right now, but I understand that this simple setup does not work with more jails in the same VLAN. > Best option is to use SR-IOV (if your interface support it) to have > multiple virtual NIC, or use bridge + epair (which has an huge > performance impact due to locking issue in if_bridge, although this is > fixed in -CURRENT by @kp) I didn't know about SR-IOV but it's very promising.
