Well, I just discovered this built in cron script called "Renew DNS for WireGuard on stale connections" that replaced my manual intervention. Woohoo

25.1, 25.4 Legacy Series / Re: Wireguard issue(s)
Today at 04:18:44 AM
I have had the same issue for over a year now.
My setup is that of two opnsense routers with a site to site wireguard connection.
Only site 1 is properly exposed to the internet while site 2 is behind a nat with no port opened to it.
Thus my setup requires site 2 to reach out to site 1 via a DNS endpoint.
The issue arises when site 2 wireguard does not update the endpoint ip address when site 1 has its dynamic public IP changed.
It is unfortunate that site 2 wireguard keeps the IP cached and doesnt update it when the connection fails.
My only remedy is to restart the wireguard service on site 2 for the new IP to be loaded.
