I have many vlans on server. IPs on those vlans are like 10.X.X.X/Y I have run DHCP. But some times users on vlan can ON their soho router like DIR-300 or so and connect their internet cable to LAN port of that router. So in my vlan I have two DHCP servers. One is mine and second is on that router. Some users get wrong IPs from that router. Can I bind 192.168.1.1 address of router to server so restrict such router to work normally? Or s there any other method to prevent such ilegal DHCP servers on LAN? -- Eugen mailto:kes-kes@yandex.ru
