Network Interfaces

For configuration management of network interfaces, go to Setup > Network Interfaces > Network Interfaces Configuration.  Refer to possible configurations in the table below.

Bridge

This section allows you to create a bridge between network interfaces.  The bridge interface has been added into the table but the settings are not populated under bridge (br0) by default.

Just LAN interfaces are allowed under bridge including eth1, eth2 and wlan1 (Wi-Fi Access Point). With this bridge interface added, it is possible to assign any number of LAN interfaces (of both Ethernet and Wi-Fi AP types) to a specified bridge. But only one bridge interface is allowed and supported.

Slave Interfaces

Slave interfaces such as Ethernet (eth0) or Wi-Fi AP (wlan1) do not have their own IP addresses and are not configured as DHCP clients.  The IP address mode, STATIC or DHCP client, is implemented on the bridge level.

Ethernet Interfaces

The Ethernet interface(s) can be configured as either LAN or WAN. Ethernet interface(s) can be set to use static pre-set IPv4 addresses or dynamically obtain an IPv4 address over DHCP in DHCP client mode.

The eth1 and eth2 interfaces appear if an Ethernet Accessory Card is plugged into the appropriate Accessory Card Slot.  The udev rules for the device have been updated to enumerate the eth1 interface with any Ethernet card plugged into the AP1 accessory port.  Likewise, eth2 is enumerated and assigned to an Ethernet card plugged into the AP2 accessory port.

PPP interface

The PPP interface is only allowed to be WAN.  The PPP interface listed in the Network Interfaces page can only have it’s mode changed.  Options are PPP and PPP addresses-only modes.

Wi-Fi integration

Wi-Fi integration is enabled by adding two network interfaces: wlan0 (used exclusively for STATION mode) and wlan1 (used exclusively for AP mode).  The Web UI as well as API back-end have been modified to add support and validation rules in order to assign LAN interface(s) to a bridge, and removing them from under the bridge.
