SuSeFirewall2 Squid and Kernel Recompilation?

Hi, we discuss few days ago about, SuSefirewall2, Squid, and transparent proxy configuration using kernel v2.4 series. I have read carefully the "SuSe network manual" and concerning kernel 2.2 series it say: " enable transparent proxy support in kernel and recompile it". I checked the kernel v2.2 series and this option is available, as proposed by manual! I also checked the Kernel v2.4 series and this option does not appear! Questions: Is this option renamed? Is this option still available in 2.4 kernel? Is this option automatically enabled or recalled by an other option? Many thanks for your advices and time;) to all List Lorenzo Rossi
