dear friends, i m from india & is using a 2 Mbps Leased Line connection, distributing it through windows 2003 server with squid & ip based filtering. frequently i suffer from problems like ip conflicts bcoz users who dnt hav internet facility track the ip on which internet is available & changes them. what is the remedy to this. is there a solution like this. for all computers that need to hav internet facility, should be in domain of the system on which squid is installed & only these will have internet facility & no other computer on LAN can access internet, dsnt matter what its IP is. whts ur opinions frnds? bye From Chandigarh to Chennai - find friends all over India.
