Port forwarding works only on local network

[Gawron10001]

Hello

I set up some cameras in my friend's buisness and i wanted to do port forwarding so he can see the cameras. The problem is that it works only on local network. I found that my router ip is different that ipv4 that was showed on what is my ip, so mybe i should call the ISP? So he set static, public IP? Also there are no other routers on the network, also i did the same thing on the same model of router back in the past (TP-LINK - TL-WR841N) and it worked just fine. 

 

I would appreciate any ideas or help.

The IPs being different is a thing called CGNAT (https://en.wikipedia.org/wiki/Carrier-grade_NAT).

 

Some ISP use that because the numbers of available IPv4 is very limited.

 

You should call the ISP and ask if its possible to open the ports.

 

I live in Brazil and some ISP uses CGNAT, My cousin had this problem to open one port, she call the ISP and they opened. Just one port and not all of them I think.
