Opening ports UDP 500, 4500 and 123

I am trying to setup my T-Mobile Personal CellSpot, essetially a Femotcell.  The device does not seem to be able to reach the T-Mobile network.  Instructions state to check the network settings to assure that ports UDP 500, UDP 450, and UDP 123 are opened.  Any idea how I can check that?

The ports are "open", however, you are behind CGN, so port-forwarding isn't possible.

It's a known issue here in the community, and the devices are not supported either by Hughesnet, nor TMobile when connecting over satellite.

Only way it may work is doing it through a VPN, even then it will most likely be extremely slow.

 

Sadly, anything above basic user things do not work over residential satellite internet. Would love to have a military channel.....lol.

 

The latency over satellite is also a killer.
