It's like chikcen-or-egg. > story for source address unknown: > --------------------------------- Yes this is what I don't get. > We perform rule and route lookups according only to the known destination. So, does it mean that if there is a rule (rula A) that matches the src addr then that rule will be just skipped in this phase (since there is no src addr yet)? Then it may find a rule that matches, from that rule it looks into a table, in that table it finds a route and a src addr. Then it selectes that src addr? Let's say the selected src addr is the one in rula A. Then, after flushing the route cache, the next lookup would match rule A and may route differently using the table pointed at by rule A. Is it correct? > Try "ip route show table all" for IPv4 addresses. I'm interested in IPv6. > Make sense? Yes, THIS does. Thanks a lot. :) But the above does not, yet.
