Manual:Detect internet

Applies to RouterOS: v6.41 +

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.
