This document is obsolete. I didn't delete it merely because, aehmm, I don't know why. Maybe for historical reasons. However, I've just deleted (3 August, 1997) parts of this document in order to not confuse you, dear reader ;-) ########################################################### UPDATE (97/07/23): Since static NAT seems to work well I've continued working on a different field (that still uses address translation): load balancing using virtual servers. See http://www.checkpoint.com/products/contnav_concon.html for an excellent description of what I mean (in fact, seeing a Firewall-1 presentation on the CeBIT this year is how I got the idea). PS: port translation works in my development version (which is not yet the one you can download !!!) Don't ask me how usefull this feature is, it was just a few lines so I addes it, maybe someone will find a use for it...
