Hi everyone,

I’ve been struggling to get my WireGuard VPN server working properly. I’ve tested both the latest official firmware and pre-release versions(1.4.1 Build 20250213), but the issue persists.

Here’s what’s happening:

• Connection works – I can connect to the VPN successfully.

• LAN access works – I can reach local devices without problems.

• Internet access fails – Websites either don’t load at all or only partially load before stalling.

• Ping & DNS seem fine 

For comparison, OpenVPN (UDP) works flawlessly under the same conditions. I’ve also tried lowering the MTU, changing ports, but no luck.

Has anyone else faced this issue? Am I missing something obvious?

Thanks in advance for any help!
