Hi all. I'm researching squid and it's ability to work with routers that support wccp. In my research it looks like folks have two options when using wccp as far as kernel modules go. One is to use the ip_wccp module and ip_gre. The other is that ip_gre in the 2.6.17 kernel includes wccp support. I'm going off of this post to the mailing list: http://www.squid-cache.org/mail-archive/squid-users/200607/0252.html And http://www.ultri.cx/tech/squid/gre-transparent.html In the above link, It's mentioned that ip_wccp module does not support transmitting so you need a gre tunnel to the router to get data back to the client. Is this still the case? In some sense, the better question is which method is the optimal if one wants to use wccp in conjuction with squid. Thanks for your assistance. __________________________________________ Errol Uriel Neal Jr. Sr. Network Administrator DFI International, Inc. 1717 Pennsylvania Ave NW, Suite 1300 Washington, DC 20006 Tel (202)452-6955 Fax (202)452-6910 eneal@xxxxxxxxxxxx www.dfi-intl.com
