Hi Pratik You're trying to extend your L2 net. Wireguard transport L3 only. You can achieve what you describe by running gretap over wireguard. I did some performance tests in such a setup where i bridged the gretap interface on the ovs-bridge. Expect some reduction in throughput. Make sure to increase the MTU of the involved paths/interfaces.
