I need to create a few temporary internet networks. I can get 100mb internet line with 1 public ip or a few public ip's. i will have anywhere from a few hundred to 3000 internet clients, wifi and hard wired. I'm not worried about wireless right now. I am wondering what type of hardware i would need to make this all work. Will i be able to NAT all of these to the public address or is there another way to set this up. I heard that if i NAT all to the public IP, i would run out of ports?
