4.4 Configuring the WAN
Before the gateway will pass any data between the LAN interface(s) and the WAN interface, the
WAN side of the modem must be configured. Depending upon your DSL service provider or your
ISP, you will need some (or all) of the information outlined below before you can properly
configure the WAN:
• Your DSL line VPI and VCI
• Your DSL encapsulation type and multiplexing
• Your DSL training mode (default is MMODE)
• For PPPoA or PPPoE users, you also need these values from your ISP:
• Your username and password
• For RFC 1483 users, you may need these values from your ISP:
• Your DSL fixed Internet IP address
• Your Subnet Mask
• Your Default Gateway
• Your primary DNS IP address
Since multiple users can use the ADSL Router, the ADSL router can simultaneously support
multiple connection types; hence, the user must set up different profiles for each connection. The
ADSL Router supports the following protocols:
• DHCP
• RFC2364 / PPPoA
• RFC2516 / PPPoE
• Static
• Bridged
• RFC1577 / CLIP
.
4.4.1 New Connection
A new connection is basically a virtual connection. Your ADSL Router can support up to 8
different (unique) virtual connections. If you have multiple different virtual connections, you may
need to utilize the static and dynamic routing capabilities of the modem to pass data correctly.
4.4.1.1 Bridged gateway profile and Connection
A pure bridged connection does not assign an IP address to the WAN interface. NAT and firewall
rules are not enabled. This connection method makes the ADSL Router act as a hub, and just
passes packets across the WAN interface to the LAN interface.
To configure the ADSL Router as a bridge, click on Setup and then click on New Connection. The
default PPPoE connection setup is displayed. At the Type field select Bridge and the Bridge
connection setup page is displayed (see Figure 4). Give your Bridge connection a unique name;
the name must not have spaces and cannot begin with numbers. In this case the unique name is
called Bridge. Select the encapsulation type (LLC or VC); if you are not sure just use the default
mode. Select the VPI and VCI settings; your DSL service provider or your ISP will supply these;
in this case the DSL service provider is using 0,100. Also select the quality of service (QOS);
leave the default value if you are unsure or the ISP did not provide this information.
