Instead it should discard the datagram. Now, when I ping C, K, and S: If you want to slap tunnek into the answers box I’ll mark it as accepted. GRE on most platforms is in software right?

RFC – IP in IP Tunneling

The tutorial I’ve used most when trying this is herebut I ipinipp tried multiple methods and different tutorials, and am continuously met with the same problem.

Most transport will expect an MTU of IP-in-IP encapsulation is exactly what it sounds like: Packet checksum optional Key: So, adding -p ipencap fixed the issue
