I have OpenWrt setup as a wireguard client, everything was working great except for my DNS issue I already posted about. However, I had a simple ip rule/route add to get this one IP over the tunnel and back "home".
Then I installed mwan3 and now have three sources of internet working. Thinking that this apparently uses its own table, is there a rule I can put in place to allow my one Wireguard client to reach its peer (back home)?
Update: I should note, I am only using mwan3 as a fail over service, I am not balancing my Internet.
And.. I can re-add the route once the connection is back up and it will work again, until it is failed over.
