Add a Subinterface Assigns additional IP addresses to interfaces. These addresses are sometimes referred to as alias or loopback interfaces. |
IP Address | Enter the subinterface IP address. |
Netmask | Enter the network mask associated with the IP address. The default value is 255.255.255.0. If several addresses are applied to an interface and these addresses are in a common network, they must use a common subnet. The system does not support supernetting. |
Interface | Choose a port location from the Interface drop-down list: • LAN • WAN After creating a LAN subinterface, it is often necessary to configure a firewall pass-through rule to permit IP packets through the system. To configure pass-through rules, choose Network > Pass-Through Rules and refer to Configuring Pass-Through Rules. |
