Andre, could you briefly comment how the new libalias+natd differ (or are planned to differ) from the old one -- e.g. do they implement keepalives, move-to-front of sessions in the hash chains, fixe to known bugs in the old one ? One common complaint with the old libalias is that performance tends to trash with time -- this seems to be due to the very long timeout (24hrs ?) for sessions, coupled to the fact that newly created sesssions are appended to the end of the hash chains so over time the lookup times tend to become larger and larger. One easy fix to this behaviour is to move to the front of the hash chain a session descriptor upon a successful lookup. This keeps fresh sessions near the head of the chain while stale ones drift towards the end. thanks luigi > Hello all > > In the FreeBSD May-June 2002 Status Report we have announced a natd > rewrite to make it's configuration options more powerful and support > more ip addresses to nat to. > > The first functional preview is available here: > > http://diehard.n-r-g.com/stuff/freebsd/ > > Please check this out and test it with real traffic.
