This procedure describes how to create an IPIP tunnel between two RHEL routers to connect two internal subnets over the Internet as shown in the following diagram: Create an IPIP tunnel interface named tun0: The remote and local parameters set the public IP addresses of the remote and the local routers. When receiving IPIP protocol packets, the kernel will forward them to tunl0 as a fallback device if it can't find another device whose local/remote attributes match their source or destination address more closely. That means you cannot send multicast via IPIP tunnel. Example 1. Enabling traffic forwarding between different interfaces or sources within a firewalld zone", Expand section "47.15. Backing up and restoring the nftables rule set", Expand section "49. Encapsulate any layer three protocol (versus just IP) Add an additional checksum (which isn't useful for TCP/IPv4) Specify a tunnel key Enforce packet sequencing Of course, these features come at a cost of additional overhead; in cases where the extra capabilities of GRE aren't needed, IPIP will do just fine.
