RESOLUTION:

When trying to delete an address object in Management GUI, we get an error " Error: Address object in use by Access rule/NAT policy.

This error would mean that the address object we are attempting to delete is already being used by  either an access rule or NAT policy.  To find out where the address object is being used:

1.      Place the cursor on the comment area and it would give you the details of where the address object is being used (as shown in image below).

2.    Download the TSR report. Search for the address object name/IP, it would show the Access rule/NAT policy where this address object is in use.

Here, Access policy table ref count: 1 would mean that the Address object is being used by an access rule with index number #1.

Now if you see the address object in the access rule, delete the access rule and you would be able to delete the address object successfully.

If address object is being used by multicast zone and multicast mode is not enabled globally and on interface, then follow the steps below to enable multicast mode:

 1. Enable Multicast support under interface advanced section.
