I am using IPfire.

I would like to redirect all traffic from (external) 1.2.3.4 to (internal) 4.5.6.7:62000 This way the source machine is met with a default page, but the rest of the world roams freely. Is this possible?

I've been trying different things, but not having any luck.

thanks.

Hey mpyusko,

Not sure I understand 100% what you're asking, but I'll take a stab at it. Sounds to me like typical port-forwarding - and again, please correct me if I'm wrong. Here are my assumptions and comments:

1) by "internal" you mean your LAN and by "external" you are referring to the Internet

2) You want to direct certain external traffic to an internal IP address and port

3) This is usually done not based on the incoming IP address (which may be anything), but based on the port specified. You would then redirect external traffic coming in over port 11111, for example to an internal IP address and port number 22222.

Again, please confirm if I've understood your question correctly.

Cheers :-)

Correct. In this case I need to do it by IP. The machine in question has a fixed ip 1.2.3.4, but I do not have access to the machine to redirect it. So I want to take all traffic coming from it using Ports 80 and 443 and redirect them to 62000 and 62001 respectively on 4.5.6.7. I tried port forwarding using IPfires's interface, but it didn't work. Perhaps iptables?

OK I understand. I am unfortunately familiar with neither iptables nor IPFire. I only use the basic firewall / forwarding capabilities of my router - they cover my needs.

Hopefully other members with the appropriate expertise will chime in. I quickly looked at the wiki page of my own distro (Arch), and the information on iptables is quite extensive. Perhaps your distro has something similar or worst case, the information in the Arch wiki may seamlessly apply since iptables is a generic linux utility.

Cheers,
