Can clients run a IPIP (protocol 4) tunnel inside Wireguard as in OpenVPN?

networking wireguard

When two subnets are connected via Wireguard, clients can communicate to each other using TCP/UDP/ICMP. Can clients run IPIP (protocol 4) tunnels in Wireguard as in OpenVPN? I'm planning to migrate from OpenVPN to Wireguard and checking if it will work.

Thanks


Solution 1:

Yes, you can run anything L3 and above (ie with IP packets) through WireGuard, including IPIP, GRE, Geneve, etc.
