Correcting my previous typo!
Something like:
iptables -t nat -A PREROUTING -i eth1 -p 4 -j DNAT --to 192.168.1.2 iptables -t filter -A FORWARD -i eth1 -p 4 -d 192.168.1.2 -j ACCEPT
the check your firewall rules with iptables -t nat -L; iptables -t filter -L
Assuming eth1 is your public ip interface and 192.168.1.2 is the ip address of your host running rip44d, this would forward any incoming protocol 4 packets to 192.168.1.2.

Sometimes the DMZ works, other times it doesn't. I've seen many people report this on the IPv6 tunnel broker forums where they are trying to forward Protocol 41 and the host is behind a NAT.
