Summary

Detect Internet is a tool that categorizes monitored interfaces into three states - Internet, WAN and LAN.

LAN

All layer 2 interfaces initially have this state.

WAN

Any tunnel and LTE interfaces will always have this state. Layer 2 interfaces can obtain this state if:

  • interface has an active route to 8.8.8.8.
  • interface can obtain an address from DHCP (does not apply if DHCP server is also running Detect Internet).

Note: WAN interface can fall back to LAN state only when physical link status changes.


Internet

WAN interfaces that can reach cloud.mikrotik.com using UDP protocol can obtain this state. Reachability is checked every minute. If cloud is not reached for 3 minutes, state falls back to WAN.

Configuration

Sub-menu: /interface detect-internet


Property Description
detect-interface-list (interface list; Default: none) All interfaces in the list will be monitored by Detect Internet
internet-interface-list (interface list; Default: none) Interfaces with state Internet will be dynamically added to this list
lan-interface-list (interface list; Default: none) Interfaces with state Lan will be dynamically added to this list
wan-interface-list (interface list; Default: none) Interfaces with state Wan will be dynamically added to this list
