Hi I'm new to Squid, so please be patient. I've installed Squid 2.6 on a Debian Etch as a transparent proxy. I can go to many web sites but suddenly I can't surf the web. I realize the problem when I make ping to gmail.com and after 10 or 20 minutes gives me Request Time Out. I saw the link http://squidproxy.wordpress.com/2007/06/05/thinsg-to-look-at-if-websites-are-hanging/ (Things to look at if websites are hanging!) and I've applied those solutions but still have that problem. What other thing can I check? Please tell me if you need more info Thanks in advanced.
