Ip route cache problem
Hello, I need some help about a routing problem on a complex configuration. The problem is that I can''t reach from services outside from my DMZ.

As I''ve read in http://gnumonks.org/papers/netfilter-lk2000/presentation.html, there''s said about the "nat" netfilter table: "This table is different from the ''filter'' table, in that only the first packet of a new connection will traverse the table.
