OK, that wasn't clear. The device that has the static IP has to be the one you want to address, in this case, a thermostat.
With the way you have it, using a hub, each thermostat would have to have its own public static IP, and if you have only one, you can only have one thermostat in use.
Using a router (and I've never understood why Mac users insist on using Airports when cheap off-the-shelf Linksys, etc., work fine with a Mac) you could port forward to multiple thermostats as long as the incoming requests are on different ports.
If they all have to use the same port there is no solution except to get more than one static IP from Hughes.
Again, understand that it is not the modem that gets the static IP - it is the device you want to address. Computer, camera, thermostat, or more commonly a router that then forwards to those other devices. -- W2K Server|Toshiba Satellite XP Pro|HughesNet IA8/1410/7000 2-watt Business Internet on .98 meter fixed | Datastorm .98 XF2 2-watt on 1990 Blue Bird Wanderlodge "Blue Thunder" 22 tons of rolling steel! |

1 edit | As far as which IP is the static one, it is an IP one higher than the modem's IP, and must use the 255.255.255.252 mask.
