You just switched to a faster Converge ICT fiber plan, but suddenly you can no longer view your security cameras on your phone while at the office. You call your CCTV installer, and they tell you that "Converge blocked the ports." What is happening?
P2P Cloud Technology bypasses Carrier-Grade NAT by establishing an outbound connection instead of waiting for inbound traffic.
| Technology | Old Port Forwarding / DDNS | Modern P2P Cloud (Tuya) |
|---|---|---|
| Router Configuration | Complex (Virtual Servers, DDNS) | Zero setup (Plug & Play) |
| Works with Converge / Globe | No (Blocked by CGNAT) | Yes (Bypasses firewall) |
| Security Vulnerability | High (Open ports to the internet) | Low (Encrypted outbound link) |
The Problem: Converge and CGNAT
Older CCTV NVR systems require a process called "Port Forwarding" to allow your smartphone app to reach the camera system from outside your home network.
However, ISPs like Converge ICT and Globe At Home utilize CGNAT (Carrier-Grade NAT) to conserve IP addresses. CGNAT essentially puts multiple households behind a single public IP address. Because you do not have a dedicated public IP, traditional Port Forwarding is completely broken. Your phone app simply cannot find your CCTV system over the internet.
Solution 1: Request a Public IP (Difficult)
You can try calling Converge customer support and requesting them to "remove your account from CGNAT" or assign you a static public IP. However, ISPs usually only grant this request to expensive Corporate/Enterprise accounts, and will heavily deny this request for standard residential fiber plans.
Solution 2: Upgrade to a P2P System (The Easy Fix)
The modern, permanent solution to this problem is to stop relying on outdated Port Forwarding entirely.
Modern smart camera systems—like the HomeSecurityPH NVR-4CH Kit or our Smart WiFi Cameras—use P2P (Peer-to-Peer) Cloud Technology.
How P2P Bypasses CGNAT:
- When you plug the NVR into your Converge router, the NVR establishes an outbound connection to a secure cloud server (like the Tuya cloud).
- Because it is an outbound connection, Converge's firewall and CGNAT allow it through perfectly.
- When you open your smartphone app, your phone also connects to the cloud server, which simply bridges the connection between your phone and your camera.
Summary
If you are pulling your hair out trying to configure virtual servers and DDNS settings on a Converge router for an old analog DVR, it's time to upgrade. Modern P2P systems eliminate networking headaches entirely, allowing you to view your property reliably from anywhere in the world.
Technical Deep Dive: Why CGNAT Exists
To understand why your traditional CCTV broke when you switched to Converge or Globe, you need to understand IPv4 exhaustion. There are only a limited number of public IP addresses in the world, and they have essentially run out. Instead of giving every single household in the Philippines a unique public IP, ISPs use CGNAT to group hundreds of houses under a single public IP address.
Because you share that IP with your neighbors, the ISP's main router blocks all incoming internet traffic trying to reach specific ports (like port 80 or 8000 for your DVR). The firewall simply doesn't know which house the traffic is intended for.
The DDNS Workaround (And Why It Fails)
In the past, CCTV installers used services like No-IP or DynDNS to map a changing IP address to a memorable domain name. However, DDNS still relies on Port Forwarding. If your ISP uses CGNAT, DDNS is completely useless. Do not waste money paying your CCTV installer to "fix" your DDNS settings?it is mathematically impossible to bypass CGNAT using traditional port forwarding.
Frequently Asked Questions
Does PLDT Fibr use CGNAT?
It depends on your plan. Older PLDT Fibr legacy accounts often still have dynamic public IPs, which means port forwarding might still work for you. However, PLDT has been aggressively migrating residential users to CGNAT. If your CCTV suddenly stopped working remotely, this migration is the likely cause.
Can I use a VPN to bypass CGNAT?
Yes, theoretically. Advanced IT professionals can set up a VPS (Virtual Private Server) and route their home network through a WireGuard VPN tunnel to regain an incoming public IP. However, this requires expensive enterprise routers (like Mikrotik or Ubiquiti) and deep networking knowledge. Upgrading to a P2P NVR is drastically cheaper and easier.
Is P2P Cloud viewing slower than Port Forwarding?
Slightly. Because your video feed must bounce off a cloud server (often located in Singapore or Hong Kong for Philippine users) before reaching your phone, there is usually a 1 to 2-second delay compared to direct port forwarding. However, modern compression algorithms (H.265) make this delay negligible for security purposes.
