I understand that it is a Worldwide Standard that all IPs assigned to 3G connections are FIREWALLED.

FIREWALLED to an extent that inasmuch as UserA and UserB both are on 3G with MNO1 they cannot access any services hosted by the other.

This is the case with Safaricom.

It also must be the case with Orange.

It must also be the case with Airtel.

It must also be the case with YU.

No?

I have a setup like this:

3G dongle < --- ROUTER ----< LAN <--- DVR

The router is a TP-Link and the dongle is from Orange (MF192).

Router IP (LAN) = 192.168.1.1
Router IP (WAN) = Dynamic (I have DDNS configured to help with name resolution)
DVR IP (LAN) = 192.168.1.10

I have punched holes in the Router firewall to redirect/forward ports 8000 and 9000 to the DVR for purposes of accessing it using web and an android app.

However, port scans to the WAN IP shows all ports are blocked!

It would appear that the only way to get this to work would be to get Cable Broadband! Suppose there is no CB in one's area then technically you are damned.

So it looks like as a rule, no one is allowed to run public services on 3G or does anyone know a provider who can give special considerations?

Safaricom is NOT one such provider. I wonder if the others can.
