Firewall
Network Address Translation (NAT) is a technique to modify network address information within IP packet headers in transit.
This enables mapping one IP address to another to protect wireless controller managed network address credentials. With
typical deployments, NAT is used as an IP masquerading technique to hide private IP addresses behind a single, public facing,
IP address.
NAT can provide a profile outbound Internet access to wired and wireless hosts connected to an access point. Many-to-one
NAT is the most common NAT technique for outbound Internet access. Many-to-one NAT allows an access point to translate
one or more internal private IP addresses to a single, public facing, IP address assigned to a 10/100/1000 Ethernet port or 3G
card.
