Having had some discussions with two readers, I did again an extensive search regarding this problem and finaly found in a Globe customer forum the following two posts.

Globe ADSL Subscribers are now within the Carrier Grade NAT

I'm not going to battle Globe legally, because I have no legal basis to begin with, but I just want to argue that putting the Subscribers within the Carrier Grade NAT, makes gaming unreliable! There will be frequent disconnections. Second it makes web hosting impossible.
Subscribing to your Static IP Add-on is absurd! 559 pesos per month for a measly thing? It's overcharged, and I don't even know if you'll still put us in the carrier grade nat!
It's always Globe (the first telco) to implement many things that would just aggravate the customers, just to save money instead of upgrading their network infrastructure to have a more reliable service, like with their FUP.
Implementation of FUP is not anymore justifiable with Wired Connections! It's not fair you also implement FUP just because of Network Congestion, Wired Connections doesn't work that way! Instead of wasting your money on advertising, sponsorship and "parades" to encourage more subscribers, why not UPGRADE your Facility?
Re: anyone successful in using port forwarding to view cctv remotely?

Perhaps the cause could be found in this thread... https://community.globe.com.ph/message/105661#105661
When Globe implemented the Carrier Grade NAT (Network Address Translator), it is causing the IPv4 to be starved or exhausted by assigning many customers to one IP address, as opposed to giving each customer their own IP address.
Opening a port on your home router will not help, because the upstream Globe NAT gateways break end-to-end connectivity.
From the subscribers point of view... tinitipid na tayo ng Globe when they could have invested and put out a better infrastructure (iPv6) or they would want us to subscribe an additional service like having a Static IP address.
Wikipedia says this about Carrier Grade NAT:
Critics of carrier-grade NAT argue the following aspects:
- Like any form of NAT, it breaks the end-to-end principle.
- It has significant security, scalability, and reliability problems, by virtue of being stateful.
- It makes record keeping for law-enforcement operations more difficult, except if the translation of the addresses is logged.
- It makes it impossible to host services.
- It does not solve the IPv4 address exhaustion problem when a public IP address is needed, such as in web hosting.
Since what I want to do (remotely accessing my CCTV camera's) is basically "service hosting", it will never be possible to do this with Globe's broadband service.
Hence, I have to move to Smart, supposing that they do allow port forwarding, however I am not sure when they have coverage for wireless LTE broadband in our barangay, as it is a rural place,
According to their website there is not yet coverage in our barangay, but they are continuously extending the coverage, so may be next year.
I found out that Smart has the same policy as Globe on their SmartBro. No "port forwarding", so switching to Smart is not a smart option.
