Using PPPoE
If you selected Using PPPoE from the Untrusted Interface Configuration page, perform the following steps to
configure Point-to-Point Protocol over Ethernet:
1. Enter PPPoE User Name and Password to use for authentication when establishing a WAN connection
using PPoE protocol.
2. In Service Name, enter the domain name of your network service provider. Use * as a default (for all
services).
3. In PPPoE Timer, enter the number of seconds of inactivity that must elapse before the PPP connection
closes. This helps to limit connection charges from your service provider during times of inactivity. The
default entry of “permanent” will keep the PPP connection open constantly, with no timeout interval.
4. Optionally select NAT Enabled. THis enables Network Address Translation (NAT), which allows multiple
workstations on your LAN to share a single, public IP address. All outgoing traffic appears to originate from
the router’s IP address.
5. Click Next. This displays the Dynamic Host Configuration Protocol page.
Not Using PPPoE
If you selected Not Using PPPoE from the Untrusted Interface Configuration page, perform the following steps
to specify how to obtain an IP address and subnet mask:
1. Select one of the following methods for obtaining an IP address:
• Obtain configuration automatically from Wan using DHCP to have an IP address assigned
automatically using DHCP.
• Configure IP Routing manually to assign IP addresses manually. If you select this option, you must
specify an IP Address, Subnet Mask, and Default Gateway in the appropriate fields.
2. Optionally select NAT Enabled. THis enables Network Address Translation (NAT), which allows multiple
workstations on your LAN to share a single, public IP address. All outgoing traffic appears to originate from
the router’s IP address.
3. Click Next. This displays the Dynamic Host Configuration Protocol page.
