Hi all, I am experiencing a strange issue with a WireGuard clients-server config.

This is my setup:

- A WRT1200AC (r51362) as a WireGuard server (secondary router).
- A WRT1200AC (r51362) as a WireGuard client (secondary router).
- A WRT1900ACS (r51362) as a WireGuard client (primary router).

They are all in different houses so the two of them are secondary behind the provider's router.

The problem:

The provider's router where the server router is connected gets rebooted every night, so its IP changes.
I have correctly setup the DNS script on all routers to update DuckDNS accordingly.

Now, for some reason the wrt1900 client is able to keep going, while the wrt1200 client hangs. I have to disable/enable the tunnel to get it working again.

What makes this even more strange, is that I have a separate tunnel between the two clients, for which I am not facing this issue.

Attaching the config screens for the 3 routers.


EDIT:

Sometimes even the wrt1900 get's lost trying to connect to previous IP.
It looks like the DNS is resolved only at first connection then, if IP changes the WireGuard client isn't capable of reconnect.

Does anyone know if there is any settings to be checked?

Thanks all in advance.

Hi Egc, sorry for late reply, I am not receiving email alerts anymore.
Anyway, we are not restarting the provider's router everyday, they do something from their and change the IP during the night.

Could you please point me to some guide or, if a quick fix, list me here what to do?

Thanks

Awesome, thank you!

So just leaving the default parameters would do the job?

Yes 😀
