http://www.tldp.org/HOWTO/TransparentProxy.html It is a guide on how to setup squid (or any other server listening on a given port) for transparent forced port redirection No need to kernel hack as that great ipchains/iptables/netfilter does it for you! Joy!
Well :) i'm using with success squid+cisco+other_linuxes_as_redirectors with wccp too. there is an info from http://www.tldp.org/HOWTO/TransparentProxy.html Note that this document focuses only on HTTP proxing. I get many emails asking about transparent FTP proxying. Squid can't do it. so HOW to do transparent of MTA, FTP, DNS or any other if the SQUID daemon is not for that???,,, and what i've seen on kernel, that the only thing working stuff with REDIRECT firewall target is SQUID .
You should be able to employ the method in this HOWTO to email filter redirection for your MTA and any other caching, filtering, etc daemons that you wish to force traffic through.
SQUID cannot pass any traffic other that WWW (as i've seen from docs), the transparent ftp cache'ing isn't possible via squid too (only acts as w3cache) So what to do ??? the only way i thing is possible is to hack dns replies for any MX, to pointer to my MTA .
If your interested in a heavier squid filter check out http://dansguardian.org/ -- Free squid filter with phrase parsing and I use the http://www.squidguard.org/blacklist/ blacklists at work Hope this helps! Philip Duldig
