I'm new to Slingbox and just bought a 350. I first got everything working locally, but when I tried to connect remotely, all I was getting was 100kbps speed and nothing was showing up. I have plenty of bandwidth on both sides, so I am starting to suspect the cable provider is throttling me some how. I've seen similar situations with this provider using port 8080 for a web server; changing to a different port fixed it.
Anyway, I've followed all troubleshooting steps provided in any forums and would now like to try changing the port the Slingbox communicates on as well as set up port forwarding. However, it seems like the option to change the port is greyed out? Is it possible to do this on the 350?
