> What happens if you'd directly bridge it to an em(4) without the lagg etc. in between Thanks, you're right, taking the lagg0 out and adding em0 to the bridge instead works indeed. Can I assume that's a bug in if_lagg then? If so, where should I report it, the freebsd-bugs list? Frank On 5/18/2011 9:51 PM, Bjoern A.

Pinging the ip of the lagg0 interface which is on the bridge with the epair0a interface /does/ work, as does pinging the aliases of the lagg0 interface (i.e. the other, non-vnet jails). >> Hope this helps. > So epair generally works; What happens if you'd directly bridge it to an em(4) without the lagg etc. in between > , would that work?
