I just started a task to upgrade our CentOS v5-based squid3/tproxy boxes utilizing the Wiki article that Amos wrote. Everything is working great and it was actually far easier to setup then it used to be. Amos, Laszlo, and Krisztian...you are amazing, and I wish to offer my sincere thanks to you guys for the work and talent that you give to the open source community. I am using the following software pieces to accomplish a WCCP-redirected TPROXY/transparent squid service in combination with Cisco routers: CentOS 5.3 x86_64 Squid 3.1.0.8 Iptables 1.4.3.2 Kernel 2.6.30 IOS Advanced Security 12.4(15)T8 on a 2811 (as the testbed router/ios combination) Amos- I can either create a new set of steps, this time more detailed and better tested, for TPROXY/SQUID on CentOS 5.3 to replace the current one that has my name on it, and/or add some details to the article you wrote.
