The FortiGate 300E firewall supports up to 10,000 MAC addresses for MAC-based policies. This allows you to create policies that can accommodate a large number of devices in your office premises. Ensure your firewall's configuration and performance requirements align with this capacity for optimal operation.Heating & Cooling In Bowmanville

Hello  @anamulomega ,

Thank you for contacting the Fortinet Forum portal.

From the max table value, it looks like you could only have a maximum of 1000 mac address please check below max table 

 https://docs.fortinet.com/max-value-table

or In the FortiGate cli type print tablesize it gives list of all max values as below article:

Best regards,

Hi @anamulomega ,

Please type "print tablesize" on your fortigate 300E CLI and look for "firewall.address:macaddr:" line. It will tell you maximum number of MAC address objects that can be created. However, I was able assign multiple MAC addresses to single (MAC address based) firewall address object during my Lab testing on a Fortigate-VM. Below is the example:

config firewall address
edit "MAC-1"
set uuid fd27b5a2-5da2-51ef-6b29-ff39d1174cc3
set type mac
set macaddr "00:43:68:61:05:02" "00:43:68:61:05:03"
next
end

Maximum value table for FortiOS 7.4.4 and Fortigate 300E shows global limit of 20,000 considering all kind of firewall address objects
