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: 1.2.3.4 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. |
Oke, i've got it working now. I forgot the postrouting. But now when i set FORWARD in the 'filter chain' the connection fails again.
Is there someone who can help me with this? |
Before we can help, could you post your iptables script, once we see what you have, we can then help to troubleshoot it.
