Chaining backup IP addresses
It is possible to chain backup IP addresses by making multiple entries in the table.
For example, if the backup IP address for the original IP address appears as the IP address in the
next row, along with a new backup IP address for that IP address. When the original IP address
becomes unavailable, the router tries the backup IP address. If that IP address is unavailable, the
router tries its backup IP address, and so on.
For example, if the original IP address is 192.168.0.1 with a backup IP address of 192.168.0.2,
setting the IP address in the next row to 192.168.0.2 with a backup IP address of 192.168.0.3
causes the router to try all these IP addresses in succession.
Note The time that it takes for a connection to an IP address to fail is determined by the
Connect timeout parameter on the Configuration > Network > Advanced Network
Settings > Socket Settings web page.
