PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It
allows your ISP to use their existing network configuration with newer broadband
technologies such as ADSL. The PPPoE driver on the Contivity 251 is transparent
to the computers on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual computers.

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).
•
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface(s)
This auto-negotiation feature allows the Contivity 251 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, allowing the host to be more easily accessible from various locations on
the Internet. You must register for this service with a Dynamic DNS service
provider.

Your Contivity 251 supports up to 8 PVC's.
•
