Network Address Translation can translate the source IP address of a LAN client to the IP
address of a WAN client before forwarding a packet from the LAN to the WAN. When the
packet returns, NAT translates the destination address from a WAN client to the address of a
LAN client before forwarding the packet back to the LAN client. When only one WAN IP
address is available, NAT can translate the only WAN IP address into multiple LAN IP
addresses for the LAN clients. Therefore the LAN clients “share” the only one WAN IP
address, and it is called “Broadband Switch.”
