Wireguard server on PiOS working, Android connects, but WG3526 won't

[DadsHockeyLife]

Ok, so after about 12 hours staight working on this, I'm about ready to throw in the towel.

I have a The Wireless Haven WG3526 router with their flavor of OpenWRT on it. I was running an OpenVPN VPN on it, but was having a config issue being able to route traffic from Home to Remote LAN. I did some research and found that Wireguard is faster, slimmer, and (at least to my mind) easier to configure.

I had a Raspberry Pi 4b lying around, so I got it up and running as a Wireguard server. I connected using my Android and everything works perfectly, including in the reverse.

So, I figured the setup on my WG3526 would be smooth too...WRONG!

I followed several tutorials step by step (using this one primarily https://www.vpnunlimited.com/help/manua ... uard-setup - although I know some mods have to made for my specific info).

I've setup an interface for it and specified the interface in the right firewall rules.

I've tried a bunch of different combinations of these and I always get this same set of errors in the log....I have no idea what's wrong. All packages are up to date, and I thought The Wireless Haven was using a current enough kernel from OpenWRT to support Wireguard....

What am I missing?

Here's the message that I get over and over again in the logs....

ANY help you all could offer would be appreciated...thanks!

Ok, so after about 12 hours staight working on this, I'm about ready to throw in the towel.

Supposedly the latest GoldenOrb firmware has WireGuard built in without having to install extra packages.
Here's the latest WG3526 firmware as of today.
ZBT-WG3526-GO2021-07-19.zip
http://www.aturnofthenut.com/upload/ZBT-WG3526-GO2021-07-19.zip

And here's the folder with all firmwares and versions.

Let us know if it worked,
