Port Map: easy UPnP port mapping

by Mat Lu Apr 21st 2008 at 10:30AM


One of the nice things about the Airport Extreme Base Station is the Airport Utility application used to manage it. Most other routers these days are managed with a web interface which can sometimes be a little wonky. So it was with some interest that I discovered Port Map, from the Coding Monkeys of SubEthaEdit fame.

Port Map is not a full-fledged management application, but it does bring Cocoa lickability to one standard management task: port mapping, an essential task for iChat or Back to my Mac. If your router supports UPnP / NAT-PNP Port Map provides an iPhone-esque Ui for setting up specific ports, including "presets and URL templates." You can see it working above with my DD-WRT Linksys router (don't worry, I turned it off after the screenshot).

Port Map is a free download from The Coding Monkeys. They've also open-sourced some of the coding goodness that makes this possible and created a framework available to other developers on a Google Code page.

Thanks constantin!

Enabling uPNP in a Router is VERY dangerous. It allows any program running on your Mac (with uPNP support) to open up ANY port on your router.

Hmm.. Think about it for a minute. If you accidentally download and run a malware off the internet, the malware could use uPNP to open up a port on your router. There goes your firewall!!

(And yes, there is a lot of malware that uses uPNP to open up ports on your firewall).

uPNP was developed and designed for users who have difficulty configuring your firewall. As usual, there is a trade-off betweern security and convenience. In this case, there is a great loss of security for a little convenience. IMHO it is not worth it.

I recommend ALL users to TURN OFF uPNP in your router.
(and avoid programs like this one which use uPNP).

Looks like a promising app. I'd love to see an iChat preset, though. And please display the protocol type (TCP/UDP) in the main window [comment based on version 1.0 (5)].

You can change every aspect of the configuration and only restart once, or you can make one small change and restart once. This is true of every router I've ever used. I've never had a problem with everything reconnecting after a restart. Just don't restart in the middle of a download/stream.

@johnny -

ive never had a router that required a reboot for things like port forwarding. my last router was the linksys wrt54g and you would just set the params, and click save.

i am always working in SSH or something similar, so i constantly have connections open and with the reboot time of the APExtreme it times out all of those connections.

i dont even remember having to reboot every time i made a change on cisco routers back in the day

my problem with the AirPort Utility is that it has to reboot after every change! even when setting up port forwarding. its insane that i have to lose all of my connections to make simple changes.

or am i doing it wrong?
