MTU size problem for WireGuard on Windows 10

Rate this question



Hello everyone,


I recently acquired TorGuard and I am very happy so far.

I have an issue with the MTU-Settings specifically for the WireGuard Protokoll and VPN Adapter.


With the default 1420 MTU for the wg-adapter it connects to the server but I literally have no internet. I went ahead and tested which MTU I actually need and I ended up with 1292 MTU size. (1264 no more ping errors  + 28 = 1292) I went ahead and connected via WireGuard one more time and changed this specific value via PowerShell "netsh interface ipv4 set subinterface “wg-adapter” mtu=1292 store=persistent" and voila the WireGuard connection now works flawlessly.


My issue is that there is literally no way to permenantely change this MTU size for the WireGuard protocol. Everytime I disconnect/reconnect to another server the Virtual adapter is removed and added again with the default values.


Is there any way to permamently change the MTU size for the Tunnel adapter?


Thanks in advance.
