    Hello Charles,

    You can't, really. Not unless you have a form of NAC or other switch based security so you can layer 3 Intercept and reroute the rogue DHCP packets.

    A cursory google brings up this spiceworks article:

    The Xg has no function for this as it occurs behind the XG.

    There are fonctions in Microsoft Active Directory regarding this.  i.e. protection for DHCP and DNS.  Look at topics like "Authorized DHCP", "DHCP & DNS integration" as well as "Name Protection".
