  • a VLAN to any switch/trunk ports (as desired)
  • the following to Firewall > Custom Rules:
# (eth0.2 in this case is the Public-facing WAN (to allow IPENCAP traffic), read your OpenWRT hardware Wiki for your specific model 
ifconfig tunl0 mtu 1480 up
iptables -t filter -I INPUT -p 4 -i eth0.2 -j ACCEPT
# ./etc/config/ampr-ripd -p <PASSWORD> -t 44 -a <44.xxx.xxx.xxx/xx>
