I found this thread: http://www.squid-cache.org/mail-archive/squid-users/200201/0136.html Quite old... This thread indicates, that the kernel module ip_gre is rather incomplete in regards to wccp handling. Regarding this thread the ip_wccp patch was created to resolve this issue. Does this still apply? My kernel is 2.4.32. Thanks. Regards, Martin On Thursday 15 March 2007 09:19, Henrik Nordstrom wrote: > tor 2007-03-15 klockan 18:27 +0800 skrev Awie: > > AW> Thanks Henrik.
