Model: ER7206 (TL-ER7206)  
Hardware Version: V2
Firmware Version: 2.2.3 Build 20250723 Rel.05551

The hardware version is 2.20. When I connect to Wireguard with Full Traffic enabled, I don't have internet access or access to the remote local network.

 

 

When I connect with Full Traffic disabled, I can access the internet, but I can't ping the local remote network.

 

 

I performed the same tests on another router of the same model, but with hardware version 2.0, and it worked perfectly with the same settings. I believe it might be a firmware issue with the hardware version V2.20.

Which exact build of the V2.0 firmware did you test with? Both hardware revisions share the same firmware image. Also, what does your VPN configuration look like? The issue might be related to the settings on your VPN server side.

  @Ethan-TP Thank you for sharing your knowledge. The version is the same. 2.2.3 Build 20250723 Rel.05551. I made the same configurations on both routers (ER7206), the only difference between them is the remote IP and the hardware version, but all the client and server configurations were identical, so I believe it's something to do with the hardware version.

 

I tested it with another VPN (OpenVPN) and it worked perfectly. I'll keep testing to see if I discover anything. Thank you very much.
