There is nothing special to do, except that you need to make sure that incoming
protocol-4
traffic on your internet connection arrives at your gateway system. And with modern
internet
routers as supplied by providers that is often impossible. You often can forward TCP and
UDP
ports only, not protocols. And when there is a "DMZ" setting that promises to
forward all
unsolicited incoming traffic to a specified host, more and more often it handles only TCP
and UDP
traffic.
It can be deceiving that the router often passes replies to outgoing protocol-4 traffic as
part
of its standard NAT function. That is not enough. It needs to pass unsolicited incoming
traffic
or else you will not see the RIP packets.

Hey Chris, Marius,
Ok, thank you for the correction though I clearly remember that "something"
additional was required before RIP updates would start flowing over the IPIP tunnel other
than the user just defining their gateway IP address for the IPIP tunnel endpoint. What
is "that".
