Best way to block a port into WAN for the whole organization
im new to Meraki MX appliances and with the recent security vulnerability in Outlook CVE-2023-23397 I'm wondering what would be the best way to block SMB Port 445 into WAN for all networks / a whole organization.
It would seem quite tedious to do this on all individual appliances allow Class A / B /C networks and then deny all others.
Any advice on this? Im used to other firewalls having simply havin a WAN zone definition or being able to select the WAN interface as destination.
