Cellular backup connections

Could be wrong on this but direct SSH on the LTE side may possibly be not allowed(filtered) and might just be something you could discuss in a ticket with Verizon.

The fact that there's a highway to Hell but only a stairway to Heaven says a lot about anticipated traffic volume.

I have another strange issue though. When I try to ssh or connect via the endpoints web interface it fails. If I first connect via PPTP or SSL VPN then it works. I ruled out it being my IP since if I connect direct from the PPTP or SSL VPN box then it fails as well. It seems the tunnel does something (perhaps lowering the MTU or fragmenting packets) that allows it to work. Any thoughts?
