Thanks, I will test in the near future.

NB: I don't know if my setup fits your setup in relation to where "host" traffic originates. My bridge does not have an IP address itself. I prefer to add an epair for local traffic.

genet0 <--> bridge0 <--> epair0a <--> epair0b

And in rc.conf:
ifconfig_epair0b="SYNCDHCP"
ifconfig_epair0b_ipv6="inet6 accept_rtadv"

This makes that epair0b is the interface of the host.
I like this setup as IMHO it mimics more how a host is connected to a switch. In this way my host is next to the jails in the bridge. Things like tcpdump-ing epair0b vs bridge0 are more predictable to me.

Ronald.
