6Enter the IP address and Netmask for the VLAN subinterface.

7Optionally select a zone to add the VLAN subinterface to a zone.

8Select the management Access for the VLAN subinterface to control how administrators on the network that connects to this subinterface can connect to and manage the FortiGate unit.

HTTPS To allow secure HTTPS connections to the web-based manager through this VLAN subinterface.

PING If you want this VLAN subinterface to respond to pings. Use this setting to verify your installation and for testing.

HTTP To allow HTTP connections to the web-based manager through this VLAN subinterface. HTTP connections are not secure and can be intercepted by a third party.

SSH To allow secure SSH connections to the CLI through this VLAN subinterface.

SNMP To allow a remote SNMP manager to request SNMP information by connecting to this VLAN subinterface. See “Configuring SNMP” on page 162.

TELNET To allow Telnet connections to the CLI through this VLAN subinterface. Telnet connections are not secure and can be intercepted by a third party.
