Speedport W 724V port forwarding

Hy guys and girls

On my workplace there is a Speedport W 724V router, it doesnt have open wrt or anything, its default, from carier.

We intstalled CCTV system and we can access it from local network (LAN), but outside connection is refused.

I understand that i have to set up port forwarding, but not really sure how (whatever i try it doesnt show like its opened a port)

Pics will maybe be of use

I want to be able to connect from home, using No-IP service

Can you help?

Basically you need to add the outside ports (or port range), the inside port (port range will be added automatically, and the internal IP.
