Hello,
Due to some new corporate cybersecurity policies, my IP Firewall Address List has over 50,000 entries. Many of these entries are address ranges.
What I'd like to do is to find a way to search the list to discover if a particular IP is covered by the range. I can do a manual comparison if I can filter the list down to something manageable.
I've tried using the filter feature in winbox. When I search the address field using either "in" or contains" I can only seem to get a search result if I give an exact match for the entire IP address including the CIDR subnet. Is there a way to do a partial match, for instance on the first two octets?
If the filter feature cannot meet my search needs, is there another search method I can use in the router? Perhaps something in the CLI?
I suppose I can export the list and open it in a word processor, I'm just curious if there is a method I can use directly on the router.
Thank you.
