bind 192.168.1.1 to all interfaces
Hi, FreeBSD. 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-...@yandex.ru ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
