Hola,
i need to ask you for something in my network, first i have a server installed with Squid package and the proxy is already activated, but i need to force my clients to use my squid automatically without they know or make any settings yet.
I think the best solution is to use DHCP, but i don't know how ...
Thanks in ADVANCE

The simplest solution is to make it transparent and make the traffic naturally flow through it to reach the internet. This is pretty crude though, and I really wouldn't recommend it, despite the genuinely zero effort required on the client side. What you seem to be alluding to is what M$ call WPAD - Web Proxy Auto Discovery, which can be done through DHCP, but does require IE to have the "auto discover" option for proxying, and similar for Firefox. the DHCP route for it, and there are a few different ways, is not too nice, I'd recommend the DNS version, where with the auto-discovery options on the client, it will try to grab "http://wpad/wpad.dat" or "http://wpad.mydomain.com/wpad.dat" or a number of other good guesses to hit a web server which will then pull back a proxy configuration file for the browser. The DHCP option basically just provides that url in a DHCP option, but it's much less supported or standardized AFAIR. So just ensure that you have a DNS alias which points to a web server which will fulfil that request and you're largely done.

Really, thanks for your reply, but i need to know, why it is not recommended ???
and how can i do this ???
