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+ Ethernet Modem 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+ Ethernet Modem 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+ Ethernet Modem 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+
Ethernet Modem 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+ Ethernet
Modem 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.
