I have a dual WAN router TP-Link TL-ER6020 and Firewalla Blue on a fixed IP which have worked fine for a couple of years.
Trying to set up VPN so I can manage the home while I am away but cannot get the VPN working. Been through all the instructions. Also removed one WAN and ensured the external IP matches up.
