    Peter this an issue that a firewall cannot managed if the network is flat.

    XG can block the dhcp requests if they traverse the firewall (layer 3) but if your computers get an ip from a dhcp in the same LAN you have to use other mechanisms to block rogue dhcp servers (nac for example and training your users).

    Regards
