Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used within one
network (for example a private IP address used in a local network) to a different IP address known within
another network (for example a public IP address used on the Internet).
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the ADSL2+ Combo Router and other UPnP enabled devices can
dynamically join a network, obtain an IP address and convey its capabilities to other devices on the network.
10/100M Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the ADSL2+ Combo Router to detect the speed of incoming
transmissions and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps
or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address,
Multiple PVC (Permanent Virtual Circuits) Support
Your ADSL2+ Combo Router supports up to 8 PVC’s.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain TCP/IP
configuration at start-up from a centralized DHCP server. The ADSL2+ Combo Router has built-in DHCP
server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to
DHCP clients. The ADSL2+ Combo Router can now also act as a surrogate DHCP server (DHCP Relay)
where it relays IP address assignment from the actual real DHCP server to the clients.
