11: Network Interface Protocols The protocol assigned to each interface defines rules for exchanging information on the interface. Table 11-3 shows the available protocol options for each of the interfaces. When configuring an interface, please make sure that the protocol selection is appropriate for the interface.

These settings may or may not be used by the interface; the interface configuration depends on both the protocol selected as well as the network requirements. For descriptions of the protocols used with the LAN, WAN, WWAN, and Cellular interfaces, see the next section, Protocol Descriptions. Most of the other protocols listed in Table 11-3 are used for VPN configuration. For example, use L2TP protocol to configure an L2TP VPN connection. For descriptions on these protocols, see Add Virtual Interface. The interfaces can be set to Unmanaged, if no protocol is desired. This setting may be used to enumerate an interface for firewall purposes. G520 Series IoT Cellular Gateway User Guide 143
