Handshake succeeds, but cannot ping. Kmod version works fine.

[PaulWieland]

I am setting up a Wireguard tunnel between a UDM and an OpenWRT Linksys router.
OpenWRT was indicating that the Wireguard handshake was sucesfull, but the UDM could not ping the linksys or vice versa.

After completely deleting wiregaurd from the UDM and then installing the kmod version of Wireguard everything worked perfectly.

I don't have much more information to share as I could not find any error messages or reason why the traffic was blocked. I did not change anything else on the UDM side.

Good to hear you got it working. It might be related to this issue: #1

I'm no longer updating the userland version and redirecting others to use the kernel version.
