Iptables port forwarding problem
I've got a linux debian box (Eth 4 kernel 2.6) with Iptables to use as a router/firewall for my networks.
The configuration at this point:
Iptables ACCEPT all input/output/forward since it's just a testbox and i don't whant to lock my self out at this point.
1. DSL modem/router
external ip: 188.8.131.52
internal ip: 192.168.1.254
2. Linux router/firewall
ip(eth2): 192.168.1.68 / 255.255.255.0
ip(eth1): 10.0.0.254 / 255.0.0.0
ip(eth0): 192.168.0.254 / 255.255.255.0
on eth1 and eth2 are the internal networks of witch eth1 is private network and eth0 is the public network.
At this point i got internet (NAT) on eth1 and eth0 so internet works on both internet networks. But i can't get port forwarding to work from eth2 to eth1 to 10.0.0.1
I've searched this forum at first, but none of the solutions i've found seem to work. I've seen a lot of PREROUTING rules, but i can't seem to get them working in any way.
I just need a working example for my (until now) simple setup. I would like to forward port 8080 to 10.0.0.1 on eth1.
Would there be someone so kind to help me out here, i'm lost at this point.
