Static IP address to other Static IP address within Verizon Wireless

[philipf]

I have 20+ static IP address I purchased with my business account for all our data devices.  When I am behind one of the devices, I can't access the other static IPs.  When I am just on the internet, not behind one of my devices, I can access the static devices.  For instance, I have a USB551L connected to a Cradlepoint router with remote access enabled.  I can access the Cradlepoint easily while on a non Verizon internet connection.  When I am on my Verizon hotspot, I can't access the cradlepoint.  Is there a setting or something I need to adjust?
