Garmin HN294DP/DI manual ADSL-mode - RFC1483 MER Router, Description

ADSL-mode – RFC1483 MER Router

6 ADSL-mode – RFC1483 MER Router

6.1Description

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).
