I am trying to ping a device with IP, subnet mask It is configured with gateway adress

Is it because the gateway subnet, and ip adress subnet is different i am not able to ping it?

Yes ping is enabled on device.

    The gateway needs to be on the same network as the host because a gateway is a host on the network that knows how to reach other networks. You would need a gateway to reach the gateway, and that is not how it works.

  • @RonMaupin Perfectly reasonable to have a gateway on a different subnet, as long as both the host and the gateway have static routes to each other? Admittedly such a setup is somewhat unusual. Commented Mar 5, 2023 at 2:50
  • @Charlieface, what the OP means is the default gateway on a device, which is to what a host will build a layer-2 frame for packets destined to a different network. That means the default gateway must be on the same network. A gateway on a different network needs a gateway on the source network to reach it because you cannot build a layer-2 frame for a gateway on a different network. You cannot have a host reach other networks without a gateway on its own network.

The gateway address must be in the same subnet as the interface address. So your device is misconfigured.

  • as I thought. Anoying when I must connect to the device in order to change the network config.

  • You could change the IP address on another device on the same network and then be able to connect to it. Say you have device 1 with IP (/24 network) and device 2 with IP address (/24 network). To connect to device 1, simply change the IP address of device 2 (assuming you can easily do so) to Then connect to device 1, change its IP address to the correct configuration and then restore the configuration of device 2 so everything is correct. If that is easier than connecting to device1 directly, due to physical access issues, that should do it. Commented Mar 4, 2023 at 0:03
