Control dynamic net mappings on AirPort Base Stations
Authored by: vykor on Nov 22, '06 08:20:52AM

For any given port, the mapping in Airport Admin Utility appears to control both TCP and UDP ports of that number...at least for my AirPort Express.

Experimentally, you can check this by running netcat / nc in UDP listen mode on some mapped port, and then ssh'ing to a remote machine and using netcat in client mode to connect to that port. Type some arbitrary text in the client to see if they arrive (you may have to type for a bit, depending on traffic, since UDP is unreliable). Then, switch the listener to an unmapped UDP port and try this again. My observations are that no data got through to this unmapped UDP port, while data did arrive at the mapped port.

Control dynamic net mappings on AirPort Base Stations

Not so with the power-over-ethernet snow basestation - opening ports only opens for TCP. This has been a major headache for me, the only solution being to create a default host (I believe that's the terminology, I'm not on my network right now).

Also - the linked file is down, Rob - do you happen to have a copy of the linked file?

Hi people!
According to my knowledge and Apple's Airport Base documentation only tcp mapping are supported. And i've decided to write this program to let you to set both tcp and udp mappings. Sorry for download site availability, my ISP makes my crazy...
