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?


Use some form of authentication. Squid is capable of ActiveDirectory auth.

What you have described so far is a basic network security failure usually seen on Windows NetBIOS networks (users being able to detect other users IPs and perform privilege escalation).
