As I understand it, the Hughesnet modem won't forward any ports, unless you have a static IP addess. To get around paying them the extra $20/mo for a static address, I am using a small embedded pc with Teamviewer software on it. I can connect to the small pc which is plugged into the router and by using teamviewer can connect to the IP cam on the local LAN. Cost of the pc and accessories was less than $120. It won't take very long to make up the difference by not paying Hughesnet the extra money.
It works very well with free OS Ubuntu on the mini-pc and best of all it only draws about 5 watts of power.
Good luck getting any help from Hughesnet. Thier tech support is totally worthless.
Take care
