First I wanted to ask if you had the chance to look at what I have written about the subject: http://wiki.squid-cache.org/ConfigExamples/UbuntuTproxy4Wccp2 It might not answer your question but it's important to first understand the scenario from both IP layer etc. Your first email is a "Re" which I am not able track back into the original thread. If you can please describe you topology and not like this: | | | | | | | | | | | Ubuntu 10.04 Transparent squid3 proxy using wccp2 on c...See my last post for more defined questions = ID:37147216 ADSLMODEM-GATEWAY --> 2801-ROUTING-NAT --> 3550-L3-ACL-VLAN --> 3550-L2-SWIT... | | | It's not clear to me and probably to some other. It's cryptic and non informative.
