Thanks. Several hot spot devices offer advanced network configs including port forwarding but it does seem the only issue here is public/routable IP addressing (sort of the whole point of this exercise. ha).
It appears business accounts can pay to get a static routable address but not consumers.
Having a better understanding of these issues of connectivity, I’m interested in knowing exactly how Weathermatic’s aircard solution works so I asked them. Here’s their response:
1. We secured contracts with all Carriers and have tech support down to the tower level here at Weathermatic.
2. We have the imei # of each card embedded in our solution with API and activation.
3. We then have a VPN from out (sic) solution into the cell carriers portals.
4. Note: This is a M2M solution for low data type end points.
