How to block other DHCP server in my network?

peter zaher

Hello,

I'm new to Sophos Community and user.

Today i faced a problem that someone inside my network reset an access point and its default setting enabled DHCP, so all devices get IP from access point.

can anyone help me.

    The better network switches can do this.   They can both block unauthorized dhcp servers as well as tracking dhcp assignments to prevent rogues frim using an ip address that has been given to someone else.

    It needs to be done by a device that sees every port, which is your switch.
