Hi! I've tried to search the web for this, but i couldn't find any userful information about it. So.. There are about 400 (or more) computers, which goes through a BSD box, doing NAT. The problem is, when all of the users do theys general daily things, than the BSD machine runs out of free ports, to do nat, and drops connections. My question is, on Linux, how is the nat working, i mean how many ports is it using for nat, and what happens when it runs out of free ports? Is there any possibility to do the nat on 2 or more machines, with something like "load balancing" or so... If there is any documentation in this topic, than pls share me. thx!
