No internet traffic through Wireguard VPN server on Opal

Opal router with wireguard vpn server was working fine until recently. Now there are two Wireguard clients on macOS that connect but the internet isn't accessible. Two clients on iPhones work perfectly.

So…I upgraded the firmware on the Opal from 3 to 4 (latest as of this week), reset the router and reconfigured everything. The same result occurs…iphone works but macOS doesn't.

Macs are on Sequoia.

Is there something about macOS preventing proper functioning?

If the connection and Internet accessing of the iPhone WG Client APP is normal, means the Opal WG server works normal.

You can test one more with the Windows WG Client APP.
It may be a problem with Mac OS, please upgrade or downgrade the OS version to compare test.
