@Navas1 we can ping @Clive_A from TP-Link, maybe he has more info about this that I don't know about. it would have been great to disconnect the unifi router.

@Navas1 ok, then I understand, you want to use ER706 as wireguard client to a remote wireguard server. sorrt but it doesn't work, there is no policy route on wireguard, so what you are trying is...

@Navas1 what are you trying to achieve, is it site to site with wireguard or is it client to site? anyway you have to allow LAN ip and wireguard IP. I don't think you can use the same IP on the LAN...

@Navas1 try and add wireguard vpn ip to.

@Eg64 to get everything up and running again, I downgraded to 5.14.20.8 and ran restore from the backup I took before I upgraded and then everything came back online,

@Eg64 yes it sounds like the same problem as me, the strange thing was that switches and access points were online at all remote sites but routers was offline, all s2s vpn tunnels were offline...
