Prestige 782R G.SHDSL Router
Internet Access 3-11
ENET ENCAP
The MAC Encapsulated Routing Link Protocol ( ENET ENCAP ) is only implemented with the IP network
protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so
that they can be understood in a bridged environment, i.e., it encapsulates routed Ethernet frames into
bridged ATM cells.
ENET ENCAP requires that you specify a gateway IP address in the ENET ENCAP
Gateway field in Menu 4 and in the Rem IP Addr field in Menu 11.1. You can obtain this information
from your ISP.
3.4.4 IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed. The ISP assigns you a different
one each time. The Single User Account (SUA) feature can be enabled or disabled whether you have a
dynamic or static IP. However, the encapsulation method assigned influences your choices for IP Address
and ENET ENCAP Gateway fields.
Using PPP Encapsulation
If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not applicable
(N/A). If you have a static IP, then you only need to fill in the IP Address field and not the ENET ENCAP
Gateway field.
Using RFC-1483 Encapsulation
In this case the IP Address Assignment field must be static with the same requirements for the IP Address
and ENET ENCAP Gateway fields as stated above for using PPP Encapsulation.
Using ENET ENCAP Encapsulation
In this case you can have either a static or dynamic IP. For a static IP, you must fill in all the IP Address and
ENET ENCAP Gateway fields as supplied by your ISP. However, for a dynamic IP, the Prestige acts as a
DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable
(N/A) as they are assigned to the Prestige by the DHCP server.
If you are using PPP encapsulation, then the only ISP information needed is a
login name and password. You only need the Ethernet Encapsulation Gateway IP
address if you are using ENET ENCAP encapsulation.
3.4.5 Internet Account Information
Before you configure your Prestige for Internet access, you need to collect your Internet account
information from your ISP and telephone company.
