How to disable outgoing PING/ICMP packets from KVM?

The KVM device periodically sends PING (ICMP) packets for network connectivity detection. This document explains how to disable this behavior and the associated side effects.

For Ethernet-Only Devices

For devices with only an Ethernet connection, such as Comet (GL-RM1) and Comet PoE (GL-RM1PE), the system sends PING packets to the default gateway to check internet connectivity. The result is indicated by the LED status.

To temporarily disable this behavior, run the following command:

/etc/init.d/S23led stop

Note: Disabling this service will also make the Reset button unavailable.

For Devices with Both Ethernet and Wi-Fi

For devices equipped with both Ethernet and Wi-Fi, the system sends PING packets to public DNS servers to verify internet access for each network interface. This mechanism is used for dynamic multi-WAN failover, ensuring that the device can switch to Wi-Fi if the Ethernet connection loses internet access.

To temporarily disable this behavior, run the following command:

/etc/init.d/S98multi-wan stop
