Hi! I have many malicious users in my LAN. Many of them has access disabled to our certain services, but if they change their ip adress we can't filter them by ip. User can change ip but his MAC adress is static, but arp -S isn't solution, because when user has new ip arp add it to cache and after arp -a we have a few entry for ip with a few MAC adresses, so trafic is passed from this ip (currently and temporary not used by other user)! How to disable arp from do this? How to set up arp table really static? Maybe is there any solutions for ipfw based on MAC? -- Bartek Siebab bs@vt.pl bsiebab@rubikon.net.pl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
