Any help would be great I'm not quite sure what sort of logon you envision with Squid as it is a web proxy, perhaps you mean authentication for browsing the WWW. However, that is a Squid issue. This page gives quite a good tutorial for using Squid as a transparent proxy, which is what you would want if you were to force all HTTP requests through Squid: http://en.tldp.org/HOWTO/TransparentProxy.html#toc4 The "Packet Filtering" and "NAT Howto" can both be found at this page in a number of languages: http://netfilter.org/documentation/index.html#documentation-howto And an excellent tutorial by Oskar is available at: http://iptables-tutorial.frozentux.net/iptables-tutorial.html I hope those links help, David
