SOME port forwarding rules will not delete

[Reluctantapple]

I created some port forwarding rules that I now wish to remove/change. 

Some deleted ok by simply clicking the red cross.

Other (see pic) have a green rich and faded red cross. They will not delete - clicking the cross does nothing.

Can somebody help me with how to delete these?

thanks

If you do a factory reset it will clear out everything. Press the recessed button for about 20 seconds until the lights flash. Remember to turn off smart setup and split the wireless channels again afterwards.

The cannot be deleted because they have been automatically assigned by UPnP.

If you turn off UPnP on the home hub, you should be able to delete them.
