Troubleshooting Tip: Cannot create firewall policies with interface 'any'
Description
This article provides a solution to enable the creation of firewall policies with an 'any' interface. This may be useful when the requirement is to choose multiple interfaces or 'any' interface as a source and/or destination interface when a firewall policy is created.
Solution
To enable the 'Multiple Interface Policies', go to System -> Feature Visibility and enable 'Multiple Interface Policies'.

After enabling 'Multiple Interface Policies', it will be possible to create firewall policies with 'any' or multiple interfaces as the Source/Destination Interface.

Note: Before FortiOS 7.4, using multiple incoming/outgoing interfaces in the firewall policy will cause the 'Interface Pair View' to be greyed out as shown below. The 'Interface Pair View' will not be greyed out on FortiOS 7.4 and above.
