Cannot delete HIKVISION port forwarding rules created bu U PnP?

[#1]

Hi, checking my new Plusnet Hub Two and spotted the attached port forwarding rules.  

They point to a HIKVISION camera and look like proprietary remote access HIKVISION rules created under UPnP?  I don't use the HIKVISION software and I would like to delete them!  When I click on the delete icon is says it completes successfully but then appear to get re-created (I am assuming by UPnP?) 

Anyway suggestions how to delete/stop them re-appearing again please?  Thanks, Peter

A question to ask is do you need UPnP enabled on your Hub?

To disable UPnP look at Advanced settings > Firewall - Configuration

or

If it is possible you'll need to disable UPnP setting on the camera.

You may loose remote access to your camera/s if you disable UPnP

HTH

Thanks for the reply, call me old fashioned but when something says it is UPnP I assume it is and I like to use it to save me time:-) well that did not go well then! 

Meanwhile...  In the real world I have disabled UPnP (also recommended by Synology for their own DSM software!) and rebooted the router, all Port Forwarding rules are now gone, thanks for help and apologies for the time to get round to this...
