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

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.
