Configuring the firewall address
In order to create the outgoing firewall policy that governs the IP address of the FortiMail

entry.
To add a firewall address for the FortiMail unit
1 Go to Firewall > Address > Address.
2 Select Create New.
3 Complete the following:
4 Select OK.

must first create groups of services that define protocols and port numbers used in that
traffic.

To add a custom service for FortiGuard Antivirus push updates
1 Go to Firewall > Service > Custom.
2 Select Create New.
3 Configure the following:
