IP Interfaces

An IP interface contains the network configuration data needed for an individual connection to the network. You can configure multiple IP interfaces to a physical Ethernet interface. You can also configure access to the spam quarantine via an IP interface. For email delivery and Virtual Gateways, each IP interface acts as one Virtual Gateway address with a specific IP address and hostname. You can also “join” interfaces into distinct groups (via the CLI), and the system will cycle through these groups when delivering email. Joining or grouping Virtual Gateways is useful for load-balancing large email campaigns across several interfaces. You can also create VLANs, and configure them just as you would any other interface (via the CLI). For more information, see the “Advanced Networking” chapter in the user guide or online help for your Email Security appliance.
