I did more research on this, and discovered a reply to a similar question in another forum. Could this be the reason why I can't get the Router Screen Capture to work, and why I am having problems port forwarding in order to accelerate dowloading BitTorrents?
"You are definitely behind a router, because your IP address begins with 10. The whole 10.xxx.xxx.xxx address block is reserved for private subnets and can't be legally used out on the internet proper.
The question is, whose router is it?
Your modem is not a router. It is a cellular-type modem. All cellular modems that I've encountered so far, and the vast majority of all wireless connections of any sort, are on private networks, behind routers and more importantly, behind firewalls.
This is a router/firewall that you do not control, and as a result, probably cannot get an open listen port set up on. (All port-forwarding instructions re intended for routers/firewalls that you control and can configure yourself.)"
