Hi my best bet is you use DMZ. DMZ is very similar to Port forwarding, DMZ just forward every single ports. If you don't want fidgeting, apply your computer local iP on DMZ setting

No, put the local iP of your cctv. Normally a router can only DMZ 1 device.

As for port forwarding.
Port forwarding has incoming and outgoing.
For example your cctv iP is 192.168.10.1, and your cctv web page port is 80(normally is 80,or you can set your own). So you need to port forward the device with iP 192.168.10.1 with port 80 as outgoing.

As for incoming, is about setting what port number you want to key in when you are accessing your cctv outside of your maxis network. Say if you set your cctv incoming port is 8080.
So to access your cctv let's say using your phone data, you need to key in your public ip follow by port 8080 (e.g 203.92.157.134:8080)

So what if you want to add another camera?
Easy, in your router key in your camera local iP, say again you want to access the camera we page outgoing you key in 80, and the incoming you key in 8081.

In the end, if you want to access your 1st cctv you key in 203.92.157.134:8080 and if you want to access 2nd camera you key in 203.92.157.134:8081.

I hope this helps

No once DMZ is applied to a device (in your case your cctv), every single available ports will be forwarded. Is a quick and dirty way to set up a single device.

Sorry i edited the previous post have a look on the port forward description
