ADSL-mode – RFC1483 MER Router

6 ADSL-mode – RFC1483 MER Router
6.1 Description
RFC1483 (2684) Bridged Mode (single PVC) with router functionality
enabled.
A new feature of the HN294d is bridge-router mode. In this mode the user
can connect an almost unlimited number of PCs to the LAN/WLAN but still
only require one IP address from the ISP (which is the standard offering of
most ISPs today). This mode eliminates the need to place an external
router behind the bridged modem on the LAN/WLAN in order to connect
more than one computer and also takes advantage of the security aspects
of using a firewall-enabled router. Everything is handled in the HN294d
making an external router unnecessary.
NOTE! In this scenario the ISP uses a DHCP server. If the ISP
uses PPP, the “PPPoE Router” or “PPPoA Router” ADSLmode
should be used instead.
The bridge-router mode means that the device operates as a bridge to the
WAN (like in the ADSL-mode “RFC1483 Bridge”) while simultaneously
operating as a router to the LAN/WLAN.
The HN294d has a built-in DHCP client that is assigned a public IP address
from the DHCP server at the ISP at start-up. The HN294d automatically
activates the NAT (Network Address Translation) and its internal DHCP
server. The built-in DHCP client will provide the built-in DHCP server with
information so that no configuration is needed (information such as DNS,
gateway, and mask etc is filled in automatically). All traffic from the
LAN/WLAN uses the same PVC (as in the standard ISP scenario).
