I've been playing around with Squid (with WCCP on) in the older version of linux kernel (2.4.x) series and it always works fine. Recently i've attempted to install Squid (also with WCCP) on a newer box with the latest linux kernel (2.6.12.2). I've copied over the old configuration file (squid.conf) and try to up the gre tunnels similar to the way i've setup the old box. When i've started testing, the transparent proxy doesn't seem to be working well (in fact, not at all). I've then attempted to point my browser specifically to use the new linux box with squid , it work perfectly. This leads me to think that it might be that the gre tunnel is not communicating with my cisco router. Any help i can get on this one? Note: Please let me know if u need more info. Desperately need to get this up. Regards, Sam
