transparent proxy with Squid?

[Louis-David Mitterrand <mito@aparima.com>]

Has anybody successfuly configured Linux and Squid to act as a
transparent proxy? I have looked at the Squid FAQ and an interesting
pointer provided by it
(http://alderan.gurulink.com/transproxy-linux21-squid2.html) but have
not succeded yet. All squid configuration options and and ipchains
commands having been entred the www requests still go right past squid.

I am using the latest Debian-potato snapshot with Squid-2.2 and kernel
2.2.7 on our masquerading firewall.

Thanks in advance for any help.

PS: are there well-known disadvantages in using transparent proxying?
(vs. configuring each browser on our LAN)
