Hi,

To block a specific port on a FortiGate device, follow these instructions:

1. Access the FortiGate web interface.
2. Go to Policy & Objects > IPv4 Policy.
3. Select Create New to set up a new firewall policy.
4. Adjust the following settings:
   • Source Interface: Choose the interface where the traffic originates.
   • Destination Interface: Pick the interface where the traffic is intended to go.
   • Source Address: Enter the source IP address or range.
   • Destination Address: Specify the destination IP address or range.
   • Service: Select the particular service or port you want to restrict, in your case port 1723.
   • Action: Set the action to Deny to block the traffic.
5. Save the new firewall policy.

I hope i answered your question .

Best regards.

If it's traffic to FGT's interfaces, you need to do it in local-in policy. For 7.4 or before, you need to use CLI.

For 7.6, you can use GUI in addition to CLI method.
