3. CONFIGURATION
Network interfaces belonging to individual backup routes are also checked before use for
flags which indicate the state of the interface. (E.g. RUNNING on the Network Status page.)
This prevents, for example, the disconnection of an Ethernet cable. Any changes made to
settings will be applied after pressing the
Apply button.
Default Priorities for Backup Routes: If the Enable backup routes switching check box is
unchecked, the backup routes system will operate in the backward compatibility mode. The
router selects the route based on the default priorities of the enabled settings for each of
the network interfaces, enabling appropriate services that comply with these network inter-
faces. The following list contains the names of backup routes and corresponding network
interfaces in order of default priorities:
•
Mobile WAN (pppX, usbX)
•
PPPoE (ppp0)
• WiFi STA (wlan0)
• Secondary LAN (eth1)
•
Primary LAN (eth0)
Example: The router selects the Secondary LAN as the default route only if you unmark the
Create connection to mobile network check box on the Mobile WAN page. Alternatively, if you
unmark the Create PPPoE connection check box on the PPPoE page. To select the Primary
LAN , delete the IP address for the Secondary LAN and disabled the DHCP Client for the
Secondary LAN .
Note: Consider there is a concept of variable WAN and LAN interfaces even if the Backup
Routes are not enabled. The situation may occur, that LAN intended interface becomes WAN
interface (because of specified or default priorities). Communication from WAN interface to
LAN interface can then be blocked depending on the
NAT and Firewall Configuration.
