Hello, from what I find in your posts, I suggest you take somme readings : - natd and ipfw (there is a tutorial in the handbook and the man pages can help) - some book on IP networking (to sort out the routers / networks ...) In your case, it seems that you could use a private network (inside) and a natd/forfarding box (your gateway to Internet). TfH > Well, I think I spoke too soon when i said it worked.
