Airwall Gateway link monitoring

Airwall Gateways have a utility to monitor its underlay network interfaces and determine if one is available for use.

Internet Control Message Protocol (ICMP) is a prerequisite for link monitoring to validate a link.

By default, an Airwall Gateway will prefer wired underlay interfaces to cellular or Wi-Fi.

2.1.x and later

Starting in v2.1.x, the Airwall Gateway has a link monitor that is fully configurable, allowing the following tunable options:

  • Custom ping destinations (Conductor enabled by default)

  • Ping rate (frequency), timeout, time to live (TTL), and failure count

  • Disable ping monitors on active link
