Public IP to the Customer? (nuts & bolts stuff)



If I were building a wireless network from scratch, could someone give me a rundown how I would…

  1. get a public IP to my customer

  2. prevent my customer from seeing the inside of my network

  3. provide a VOIP service to my customer

Currently I use a fairly standard routers that connects with PPPoE and has VOIP ports, WiFi & DHCP. The router has the public IP and performs NAT. This is usually on a large providers network I’m reselling.
