While it is not a panacea, the still developing HamGate project could help.
Go to
http://hamgate.ampr.org and make sure to click the docs link. There
are operating HamGates in ME, MA, RI, CT, NY, NJ & PA. There is movement
for one in MD and possibly OH. This was all borne out of the frustration
of 44net allocation holders with IPIP issues or those behind NAT situations.

You are behind a nat on cellular, which shares one public IP with many
and doesn't allow routable ports/protocols.
The only solution would be to get a public IP address from a home
connection or a vps, and setup a VPN to access it from remote.
I could be wrong, but that is my understanding at this point.
Not only that, but
some VPSs do not allow loading the IPIP module, which
means that a full KVM virtualized private server is the only solution
short of setting up a VPS to announce a /24 via BGP.
