In /etc/rc.conf:
ifconfig_em1=3D"up -vlanhwtag" # You may or may not want hwtag -- try bot=
h
vlans_em1=3D"vlan1"
ifconfig_em2=3D'up -vlanhwtag"
vlans_em2=3D"vlan2"
create_args_vlan1=3D"vlan 1"
ipv4_addrs_vlan1=3D"192.168.12.34/24"
create_args_vlan2=3D"vlan 2"
ipv4_addrs_vlan2=3D"192.168.56.78/24"
The em0 i/f should be configured as usual. This will create virtual
interfaces vlan1 and vlan2 which you can apply firewall rules to etc.
Cheers,
Matthew
