Hi, I was looking through the trpoxy read me file and came across To apply all patches except the 04-nat_delete: cd /usr/src/linux for i in <pathtocttproxy>/patch_tree/0{0,1,2,3}*.diff; do cat $i | patch -p1; done then enable conntrack, nat and tproxy support in your kernel config. i looked through the .config file but could not find either of these three (conntrack, nat and tproxy). Could you please tell me what the above statement means. I am trying to setup squid transparent to both the server and client. Thank you, Mohammed Riyaz P.
