Port forwarding - without NAT.

[wamatt]

Hi All

Been reading the IPTABLES forwarding example, however my case is different as there is no nat involved.

I have two machines on a network both with public IP's

200.0.0.1 and 200.0.0.2

I want to forward 443 on ppp0 interface on 200.0.0.1 to 443 on 200.0.0.2

/sbin/iptables -A INPUT -p tcp --dport 443 -j ACCEPT 
/sbin/iptables -A FORWARD -p tcp -i ppp0 -d 200.0.0.2 --sport 443 --dport 443 -j ACCEPT

Is not working for me.. I think its because I left out the PREROUTING.. though all examples I've seen use NAT.

Thanks for any help

Come on fella's - anyone have any idea?

Hmm I'm actually think that you would still need NAT. Even though they both public IP's, since your still essentially "translating" packets.

Bugger even if I try to use iptables I get:

iptables v1.2.9: can't initialize iptables table `NAT': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

BTW the distro is debian.
