On the offchance that your ISP is also bahnhof.se via Zitius, here is a
config that works well for me. vlan101 is my external interface and the
rest are my internal networks. I run this with the following rc.conf
settings:

dhcpcd=YES
dhcpcd_flags="-d -t 0 -L --waitip -c /etc/dhcpcd-script vlan100 vlan101 vlan103 vlan104 vlan105 vlan106"
