I have the same interfaces on my netbook. I use trunk in the following way.
root@varis:etc:0# cat hostname.re0 up root@varis:etc:0# cat hostname.urtwn0 nwid "De Gaulles" \ wpakey hackme up root@varis:etc:0# cat hostname.trunk0 trunkproto failover trunkport re0 trunkport urtwn0 dhcp !/sbin/pfctl -f /etc/pf.conf The wifi and wired are different subnets, so I am reloading the pf rules with: sh /etc/netstart trunk0 It could be possible to write pf rules that do not need reloading.
