Ping is not possible, but this is not the issue. ( my router at home will not respond as I did block Ping actions)

on my GL-iNet AXT1800 router it is working fine with the Wireguard client.
I can see the following installed:

wireguard-tools 1.0.20210223-2
kmod-wireguard-backport 4.4.60+1.0.20211208-1

and on the AX1800:
kmod-wireguard 4.4.60+1.0.20200611-2
wireguard 1.0.20200611-2
wireguard-tools 1.0.20191226-1

I would expect it should be working with the AX1800 also or do you have an option to align the AX1800 software with the AXT1800.
I did buy the AX1800 because with would be a better fit but now it looks like a waste of money… hope to hear the solution!!
