Hi Guys,
If I want my server to be accessible from the outside of my gateway (eg. my home broadband router) and I didn't have access to the router itself (say it's being guarded by an angry troll with a mace), is UPnP the technology I would need for my server to request NAT port forwarding from the outside world to my home network?
For instance; I have a WD World Book NAS drive, which I can access when I'm not at home via a Java Applet on Western Digital's web site. The applet can connect to my NAS drive and read/write to it, but I never configured NAT on my router to allow this.. Did the NAS drive use UPnP to negotiate permanent port translation with my router?
Many Thanks,
Tom

Can't say if your nas uses upnp, probably it does, but it's not sure, it may use other techniques like udp-hole-punching.
-edit-
You can easy find out by using upnpc (in AUR) and issuing something like:
upnpc -a YourLanIp ARandomPort ARandomPort tcp
And, eventually, wait for an error message .

Thanks, I read somewhere that 99% of all routers made after 2002 support UPnP, but I guess the only way to find out is to try it!
Do you know of a UPnP cli tool for adding/removing/listing ports to a machine via UPnP?
Or is there already something in the GNU toolset for doing this?

Thanks, I'll try upnpc!
