Hi Marek,
Thank you, but as far as i can see it doesn't solve my problem. I need to disable a NAT rule to re-enable contacting the management web site.

If nothing seems to work i see no other option than trying resetting through the CLI and then restoring from a recent backup.

Did you try to enter the above command and access the Admin Portal (Web GUI) to disable the NAT rule?
