Gateway question


Is it possible that a computercannot ping it's gateway, but can ping other computer's in the lan.

I am writing a network monitor script, this is one of the cases i want to consider to avoid split brain scenario in a ACTIVE-PASSIVE cluster.

It is possible for the gateway router to be configured not to respond to pings. That would be a pretty unfriendly thing to do since it makes it harder to debug basic connectivity on the LAN, but it's certainly possible.

Yes it's possible. Even if a system's default gateway is completely down, that system can still communicate with other hosts on the LAN.
