Once you have created a new firewall policy, you need to configure it to allow traffic on port 443. Follow these steps:

• Enter a name for the firewall policy to identify its purpose.
• In the "Incoming Interface" field, select the interface through which the traffic will enter. This could be the WAN (Wide Area Network) or any other appropriate interface.
• In the "Source Address" field, specify the source IP address or range for which you want to allow traffic on port 443. This can be a single IP address, a subnet, or a specific address group.
• In the "Outgoing Interface" field, select the interface through which the traffic will exit. This could be the internal LAN interface or any other appropriate interface.
• In the "Destination Address" field, specify the IP address or range of the destination server or device where you want to allow traffic on port 443.
• In the "Schedule" field, select the appropriate schedule if you want to restrict the allowed traffic on port 443 to specific time periods.
• In the "Service" field, select "HTTPS" to allow traffic on port 443. Alternatively, you can create a custom service if required.
• In the "Action" field, select "Accept" to allow the traffic through the firewall.

By configuring these parameters, you define the specific conditions under which traffic on port 443 will be allowed through the firewall.

Step 4: Applying and Testing the Firewall Policy

After configuring the firewall policy to allow traffic on port 443, the final step is to apply the policy and test its effectiveness. Follow these steps:

• Click on "OK" to save the firewall policy.
• Click on "Apply" to apply the changes to the Fortigate Firewall configuration.
• Test the firewall policy by accessing a service or application that uses port 443. Ensure that the communication is secure and uninterrupted.
• If the traffic is not allowed as expected, review the firewall policy settings and make necessary adjustments.

It is crucial to thoroughly test the firewall policy to ensure that it functions as intended and allows secure communication over port 443.

Now that you have successfully opened the 443 port in the Fortigate Firewall, you can securely access web applications, establish remote desktop connections, or utilize other services that rely on the HTTPS protocol. Remember to regularly review and update your firewall policies to adapt to changing network requirements and security threats.
