Set-up NAT Port Map Daemon?

[richddean]

I have a small little web app that I have running on my Pi and I was trying to set-up my router to do port fowarding to the Pi so that I could access it outside of my home network, but I can not get it working. Then I noticed that when I use that bit torrent client "Transmission" that it is successfully opening a port through "NAT PMP"(??). So my next thought was maybe I could run something on my Pi that could use this "NAT PMP" protocol to tell my router to route a certain port request to my Pi. Plus there would be the added benefit of not having to configure my router.

I found two Linux daemon's(??), does anyone know how to install and set-up either of these programs or maybe some other way to do this with the Pi?

Thanks!

NAT PMP will generally only help a connection going out. It probably won't allow you to get into the Pi from outside.
Manual Port forwarding is the way to go.

Yeah, you are probably right. The manual port forwarding through the router is probably the way to go. But some how "Transmission" is opening up the incoming port because when I am running "Transmission" I can run a port check (http://www.canyouseeme.org/) and the port is open and listening.

I just wish I knew how "Transmission" is doing it if only out of curiosity.

Thanks.

NATPMP is doing it, however it opens ports dynamically.
Perhaps there is a way to set it to open a static port ? I'm not too sure. I haven't played with NATPMP much as I don't have a router capable of it at the moment
