5.2.1.1 What NAT Does NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host.
outgoing packets, the ILA is the source address on the LAN, and the IGA is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks.
5.2.1.4 NAT Mapping Types NAT supports five types of IP/port mapping. They are: 1. One-to-One: In One-to-One mode, the DSL-2120/2120W maps one local IP address to one global IP address. 2. Many-to-One: In Many-to-One mode, the DSL-2120/2120W maps multiple local IP addresses to one global IP address.
ILA3 IGA1 ILA4 IGA2 … Many-to-Many No Overload ILA1 IGA1 ILA2 IGA2 ILA3 IGA3 … Server Server 1 IP IGA1 Server 2 IP IGA1 Server 3 IP IGA1 5.2.2 DMZ A demilitarized zone (DMZ) is a host between a private local network and the outside public network.

special identification marks or headers to incoming packets, QoS determines which queue the packets enter, based on priority. This is useful when there are certain types of data you want to give higher priority to, such as voice data packets given higher priority than Web data packets. The main goal of QoS is prioritizing incoming data, preventing data loss due to factors such as jitter, delay and dropping.

The non-selected setting part will be treated as “don’t care” and the system will not handle this setting part. If the original packet does not have 802.1q tagged header, system will not add header for this packet even the detail setting condition has adding 802.1p priority ability.
