Wireguard on Windows: Unable to set interface addresses, routes, dns,

  • 772

I have installed Wireguard on Windows 7-32bit And set the config:

[Interface]
PrivateKey = *********
Address = 172.22.2.2/24
DNS = 172.22.2.1

[Peer]
PublicKey = *******
AllowedIPs = 0.0.0.0/0
Endpoint = ******:8755
PersistentKeepalive = 45

Pretty sure that the DNS setting does not matter, since I have '#' it and set it to '8.8.8.8' while everything the same. AllowedIPs neither matters since it was set as '172.22.2.1' & '172.22.2.1/24'

It did connect at first, but quickly fails. The pop-up sugguest everything goes wrong from

Unable to set interface addresses, routes, dns, and/or interface settings

Here is the entire log for a single trial of connection:

  1. This won't apply to your case according to your configs, but i ran into the exact same behavior and thought maybe someone else could use my solution: After testing a lot of different things (reactivating IPv6, building the client from scratch, running with different users, multiple reboots, etc), it turned out that the windows client doesn't seem to like MTU values in the tunnel config. Simply removing that entry solved this issue for me, so perhaps if you remove the keepalive, it will solve it.
