CCTV and port forwarding

I have a CCTV system connected to my router. Every 4 or 5 days the device number on port forwarding changes automatically so I can’t view the cameras on mobile devices (in or away from home). When I go into the firewall and change to a different number From the drop down menu it works again but then after a few days we are back to square 1.
Why does the “device” number keep changing by itself which disables the mobile view?
Thanks guys
TK

A bit more info might help, make and model of DVR, cameras and router.
If nobody knows the system then maybe someone will lookup the manuals to see what’s going on.....

This seems quite comprehensive. Have a scan through it and check if you have covered all the essentials.

You may have already done this, so sorry if I am repeating something you've already done.
Is your CCTV system on DHCP from your router? If so turn it off and set it to manual internal IP's. This will mean upping the DHCP range. So for example, I assume the Hub One is 192.168.1.x (/24 I believe). So I'd set it to 192.168.1.20 and above, and anything else beneath it is fixed on your network. Then it is just a case of setting your CCTV with a fixed internal IP below that.

I thought ISP frowned on port forwarding as it introduces a security problem into the system, I know Virgin were against port forwarding when I was with them.

You can achieve the same thing using the Hub One to always give the CCTV system the same IP address without making it manual.
Open https://192.168.1.254/ then go to Advanced Settings > Home Network. Find your CCTV system in the representation of your network and click on it.
You can then toggle the option to 'Always use this IP address' for that device (or every device on your network if you aren't sure which one is the CCTV).
Hit 'Apply' and you should find the CCTV system stops changing address on you.
Hope that helps,
Mark

I just tried that but when I select “apply” it comes up with an error message saying...
“Home Network Name
Home network name already exists in Plusnet Hubs database”
@Alex it is definitely a Hub One yes.

Fair enough @TK
I am not at my sisters, so I can't check hers at the moment. Yet - if I go over tonight I will post back.
I assume Bob can remote into your router and take a look if you PM your details.
Sorry this post isn't much more help.

Hi @TK,
I've never had that message, but I would guess it is that the 'network name' is already being used for something else.
This entry should actually the 'network name' of the device - 'cctv' for example, and should be unique on your home network.
An example from my Hub One:
Hope that helps!
