Remote Access/Static IP

Mr.Robot255

My ISP has given me a Static IP , in the coming weeks i will be buy some cameras for the home (not sure which ones yet will decide that later)

So my question is:

The modem/Router provided by the ISP is pretty much locked down, i have access to parts of it. I have access to port forward part.
I am slightly confused with the IP addressing given to me.

So the IP address given to me is 89.*.*.* with a subnet mask of 255.255.255.0 (/24), can that be right ? i thought i would be given like a /32 or /30
My default gateway given to me is 192.168.*.* a private IP.
Here is the info from my ISP router/modem ( i have LTE wireless Broadband)


I have then got my own TP link connected to the ISP router. With all devices connecting to my own router only.


Hoping i gave all relevant info needed. The private to Public to private is throwing me here. Where do i set up the forwarding is it on my TPlink or the ISP provided router. I tried giving my TPlink the static IP of 89.*.*.* and i lost access to it so had to reset it and start over.

Any comments appreciated. At the moment this will be first time i am trying port forwarding so doing it as a learning process too.

Who says your ISP-provided device is the only one on that same subnet?

Both ends of the connection between your TP-Link and the ISP device should have IP addresses in 192.168.15.0/24. You have to configure the TP-Link's default gateway or router to be the ISP device (probably its internal IP address on the 192.168.15.0/24 subnet). That way, you will NAT 192.168.0.0/24 <-> 192.168.15.0/24 <-> whatever your static routable IP address is.

You may need to set up port forwarding twice: once on the ISP device to forward to the TP-Link and a second time on the TP-Link to forward the internal nodes on the 192.168.0.0/24 subnet.
