Can't access gateway on network

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.

Regards,

Bill

Most probably this device (10.4.240.125) has a different netmask or gateway setting
my thought too, or an ACL?

Have to agree. Sounds like your Servers/Printers/other resources have a netmask of /22 (255.255.252.0)and the router is using /24 (255.255.255.0)

Within a network all network settings like netmask & defaultgateway (and network part of the address ) need to be the same.
(Different netmask breaks that expectation  the network part is different.  so it works only on a prt of the network).

Thanks to all. I don't know why that one slipped by me.

Thanks, again.
