Hi, This is the 7th time I am reading lartc.org howto and now got the reason why I could''t understand it for so many days. It starts real good with cool basics, but on Chapter 4 "Rules - routing policy database" it gets complicated very fast. e.g. it mentions /etc/iproute2/rt_tables file but does not tell what it does, and what all other configuration files do. It is like learning a language by reading a dictionary - not an easy way. Also, easy examples are not shown and the author has graduated to complex examples so soon. Is there any easier to understand guide for me and other like me? Thanks in advance. With warm regards, -Payal
