Telkom LTE Port Forwarding for CCTV

Hi All,

I have the Telkom LTE Uncapped deal with the Huawei B351s (from the bottom of the device).
I also have a new Hikvision CCTV system.

I have setup the Hikvision DVR as a fixed IP which I can see over my network (from the PC and mobile phone).
However, I'm trying to figure out how to do the setup to allow me to check the CCTV remotely.

I setup the Port Forwarding option on the router (Security->Virtual Server) but this doesn't work.

I've done a port scan on my public IP and it says everything is blocked. Before I moved to the LTE I had setup a webserver I was able to view remotely using No-IP DDNS. This no longer works either.

Anyone with any knowledge of how to get this working?

Thanks!
