Watchguard on GLAC750 issues

I have GL-AC750 and have setup my own WatchGuard server on cloud VPS.
Connecting through laptop client, works.
Connecting through router, it makes the connection, but no internet while connected.
I am connecting through another home router.

Thank you

check if you have PersistentKeepalive config in the wireguard

Thank you for your reply @alzhao !
I don’t see PersistentKeepalive in server settings, so i assume its not. should it be?

Try adding the following line to the bottom of the Wireguard client config file:

PersistentKeepalive = 25

I do not work for and I am not directly associated with GL.iNet
