Port forward with different public and private ports

[starfire]

Hi,

Just received my Sky router but not yet been activated, so having a play while waiting.

What I used to be able to do with my old router was port forward internet (WAN) port say 6666 to an internal IP say 192.168.1.53 and onto private (LAN) port 22. This gave me a bit better security as I didn't open obvious ports like FTP, SSH etc but internally all my s/w still used the normal ports as the router would take port 6666 and foward it to port 22 automatically (so I didn't need to reconfigure my FTP, SSH servers with strange ports).

ie.

Public Port Private Port IP Address
6666 22 192.168.1.53

It doesn't appear possible to redirect a port forward from one port to another with the Sky router - can anyone confirm this or am I missing something obvious?

Thanks!

Welcome to the site starfire

As far as I know you cant do that, the only thing you can do is forward it to the internal IP of the PC you want it to go to.

Hi,

Thanks for the welcome!

That was my fear, oh well, I'll just have to change my software to use different ports then - not too much hassle.

Cheers.

Try poking around in the tech forum it might be right up your street

Yep, already have a look :-) , I may try using my Belkin router again at some point but wan't to see everything working OK with this netgear one first.

If you're happy to wait a bit (a few days - I have a zillion things on at present) I'll post over in the tech forum how to do port address translation on the router exactly as you want. It's quite convoluted (it doesn't involve the web UI at all), so I want to simplify the process before publishing it or I know I'll be inundated with "how do I...?" requests.

Ok cool - presumably use of iptables?

Bingo!
