Brian, the problem I see if if I setup another rip44
listener gateway, how do I
direct the encapped traffic to our natted, internal IP? An entry in the portal
will get it to their router (outside address), but having them place a
forwarding rule to get it from there to out 192 internet address probably won't
happen.
I'm unclear on the topology of your network; I'm going to assume that
the separate clusters each have a separate NAT/firewall protecting them.
In that case, I believe you may get the IPIP traffic to pass through the
NAT/firewall to the internal host by designating the internal host as a
DMZ host. You would then register the NAT/firewall's public IP address
as the gateway host.
I'd wager it depends on the software in the NAT/firewall so some may do it
and others may not. I heard that OpenWRT does handle IPIP encapsulation.
I've not tried that myself so others who have done so should comment on
whether this approach actually works.
I'd much appreciate you writing up what you wind up doing and publish
it on the wiki so others may share your experience.
