@Vincent-TP It popped up as an update in Omada. I'd attach a screenshot to this reply if it would let me.

The last firmware version for my ER7412-M2 did have my wg server as an interface when running ping diagnostics in standalone mode. It was removed in the latest firmware update.

I need the release notes for the newest firmware 1.1.7 Build 20260305 Rel 22561

Noticed that in diagnostics>ping>interface the option is missing in this latest fw update to select my Wireguard interface so I can ping clients/tunnels. Was this an intentional or unintentional...
