I have a network with the range 10.4.240.x to 10.4.243.x. I should be able to reach / ping any device on the network from any address. For the most part, I can. The servers /printers and other resources are all on the 10.4.240.x subnet. From any other subnet I can ping the servers and printers and access them fine. What I can't ping or access is the routers gateway on 10.4.240.125. It does not respond to a ping request and isn't accessible. Any computer on anything other than 10.4.240.x does not have internet access because the device can not see the gateway. I have no idea why this one ip address isn't responding.
I'd appreciate any ideas to try to resolve this problem.
