Re: Air Card Remote Access I have the same setup as the OP. I have a cradlepoint, with a Pantech UML290 modem.
From what I've found, the UML290 is designed to provide you with a "internal 10 IP address" and there is no work around for it.
I tried using NO-IP to redirect, but it will not work.
I was trying to access my camera DVR system in my home.
OP: have you found any solution?
