IP Aliases
IP aliases are a way of defining or reaching a subnet that works in the same space as the regular network.
As you can see, the configuration is very similar to the static protocol; only in the example a 99th subnet is
defined. Now if some device has an IP in the 99 subnet (192.168.99.xxx) and the subnets gateway metric is “higher” and
the device is trying to reach the internet it will reroute it’s traffic not to the gateway that is defined in common
configurations but through the one that is specified in IP aliases.
You may also optionally define a broadcast address and a custom DNS server.

Backup WAN configuration
Backup WAN is function that allows you to back up your primary connection in case it goes down. There can be
two backup connections selected at the same time, in that case, when primary connection fails, router tries to use
backup with higher priority and if that is unavailable or fails too, then router tries the backup with lower priority.
