Manual Restart Of WireGuard Needed After Internet Connection Loss

[cust0m]

Hi guys,

I set up a tunnel between my OPNsense firewall and an OpenWrt Router.
So far erverything works great, until one site loses the internet connection.

Then, a restart of the Wireguard service on the OPNsense firewall is needed. Otherwise, no communication over the tunnel is possible, i.e. network A can't reach network B and vice versa. The "last handshake timestamp" on the OPNsese dashboard is also not updated  and restarting the tunnel on the OpenWrt Router does not help.

I've even configured both ends to send keep alive packets (25s), which does not change anything.

Is there any chance to change this behavior? I.e. the tunnel should be reestablished after one site comes up again.

Best Regards

Hi guys,

One site simple had a wrong port specified for the Endpoint :)
Therefore, only one site was able to bring the tunnel up and as mentioned if the IP had changed that was not possible because the DNS record was outdated
