Hello

I'm setting up some music streaming apps (Subsonic & jRiver Media Centre) to be accessible from outside my home, using my phone 3G service.
I've successfully port forwarded on other routers to enable this functionality, but after following the instructions on portforward dot com for my modem/router I am still unable to get into my media servers from outside the network.
I've triple-checked that the ports are correct. I've plugged my computer directly into the modem/router (I usually connect it to a Cisco bridged router in order to get more ethernet ports). I've confirmed that I'm using the correct static IP address for the computer that runs my media servers.

I'm out of ideas, but there are a lot of settings on this router that are way over my head.
Can somebody recommend a trouble-shooting process for me, please?
