Search domain on Wireguard

Technical Support for Routers VPN, DNS, Leaks

I was using Wireguard up to the last update (4.6.2). Before that, I could add a search domain to the DNS configuration on Wireguard, iike:

DNS=192.168.20.0, mydomain.local

Now the router doesn't allow me to enter a search domain on the DNS setting, which is a common Wireguard configuration.

Is there a way to achieve this?
Best,
Francis

192.168.20.0 is a network address, not an IP.

Change this value to the IP of your DNS server/forwarder.

This was not the real value, it was just an example. LEt's say

DNS=8.8.8.8, mydomain.local

is not working.

I am having the same issue. Hope there is a resolution soon. For now my workaround is to manually update this on each client.

Just a nitpick - this would depend on the subnet mask, technically.192.168.20.0 would be a valid IP address if the subnet is 21 bits or larger.

Edited: had to correct, 22 should still use 20.0 as network - 21 or larger would be correct. My bad.

True, but many software will just break then ... :smile:

Yes, my ISP assigned me a .0 address once, it caused some issues with some sites. Short-sighted filtering methods - but I was the one who paid the price for their crap filtering. I just changed my MAC and got a new address once I got tired of messing with it.
