If I were building a wireless network from scratch, could someone give me a rundown how I would....
get a public IP to my customer
prevent my customer from seeing the inside of my network
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.
