Enable IP Fallback: Select YES to enable the IP Fallback. Enable this option if you have two paths (interfaces) config‐
ured with WAN (internet) support. An example would be primary ethernet (eth0) and secondary wireless (ppp0).
Note: When using an ethernet port setup as DHCP Client, choose: Use Remote Gateway as Default Route: NO in the
ethernet port setup screen. Default route control will be managed by the IP Fallback instead.
Select Primary Interface: Specify your desired primary interface for IP Fallback behavior.
Select Primary External Command Script: Choose the name of the command script to be executed when the associ‐
ated interface becomes active. For example, if a RestartVPN is an option, then when selected, it will be run whenever
the fallback logic selects and activates this interface.
The recommended setting for this field is None for standard operation with no special behaviors. RestartVPN is useful
when using and IPSEC VPN tunnel.
Select Secondary Interface: Select the secondary interface to be used for IP Fallback. Selecting vrrp will coordinate
with the VRRP process, so that when the primary interface is determined to be unavailable, VRRP will stop broadcast‐
ing availability.
Select Secondary External Command Script: Choose the name of the command script to be executed when the asso‐
ciated interface becomes active. For example, if a RestartVPN is an option, then when selected, it will run whenever
the fallback logic selects and activates this interface.
The recommended setting for this field is None for standard operation with no special behaviors. RestartVPN is useful
when using an IPSEC VPN tunnel.
Enter Primary Test IP Address (Required): Specify the IP address of a host with which the IP Fallback service will com‐
municate to test connectivity. Value must be a pingable address, and not a domain name. The best choice would be an
address that represents end‐to‐end connectivity.
Enter Request Interval (in seconds): Specify the time, in seconds, to wait between connectivity tests. The minimum is
10, maximum is 600. Note: This value should be 30 or higher for PPP connections.
Number of Test Packets to Send: Specify the number of 0 byte ping packets to send out to test connectivity. The mini‐
mum is 2, maximum is 30. The recommended setting for this field is 5 ‐ 10.
Allowable Test Packet Loss: Specify the number of lost packets that are acceptable before the IP Fallback service will
consider the link unavailable, and switch to its secondary. Note: the value must be less than the number of test pack‐
ets set via Test Packets to Send.
Select Debugging Level: Specify a debug level for logging purpose. This is recommended only when existing configura‐
tions do not function as expected, and when directed to change by Red Lion Technical Support.
• Click on the “Save” button for changes to be saved without activating the interface until you reboot the unit, the
