These fields
display only if
your ISP
requires a
login.
Encapsulation Encapsulation is a method for enclosing multiple protocols. PPP stands
for Point-to-Point Protocol. The choices are:
• PPPoE (PPP over Ethernet)
• PPPoA (PPP over ATM)
Login The login name provided by your ISP. This is often an email address.
Password The password that you use to log in to your ISP.
Idle Timeout
(In minutes)
The number of minutes the modem router keeps the Internet
connection active after there is no Internet activity from the LAN. You
can enter a new value in minutes. Zero (0) means never log out.
Internet IP
Address
• Get Dynamically from ISP. Your ISP uses DHCP to assign your IP
address. Your ISP automatically assigns these addresses.
• Use Static IP Address. Enter the IP address, IP subnet mask, and
the gateway IP address that your ISP assigned. The gateway is the
ISP’s gateway to which your modem router will connect.
This field displays only
if no login is required.
Use IP Over ATM (IPoA). Your ISP uses classical IP addresses (RFC
1577). Enter the IP address, IP subnet mask, and gateway IP
addresses that your ISP assigned.
Domain Name Server (DNS) Address The DNS server looks up website addresses based on their names.
• Get Automatically from ISP. Your ISP uses DHCP to assign your
DNS servers automatically.
• Use These DNS Servers. If you know that your ISP does not send
DNS addresses to the modem router during login, select this option,
and enter the IP address of your ISP’s primary DNS server. If a
secondary DNS server address is available, enter it also.
NAT (Network Address Translation) NAT assigns private IP addresses (10.1.1.x) to LAN-connected
devices.
• Enable. Usually NAT is enabled.
• Disable. Disable NAT, but leave the firewall active. Disable NAT only
if you are technically skilled and are sure you do not need it.
1
• Disable firewall. This disables the firewall and NAT. This removes the
usual protection for your network.
Router MAC Address The Ethernet MAC address used by the modem router Internet port.
Some ISPs register the MAC address of the network interface card in
your computer when your account is first opened. They will then accept
traffic only from that MAC address.
• Use Default Address. Use the default MAC address.
• Use Computer MAC Address. Copy (clone) the MAC address of the
computer that you are now using and use that for the ISP. You have
to use the computer that is allowed by the ISP.
• Use This MAC Address. Enter the MAC address you want to use.
1. Disabling NAT reboots the modem router and restores its factory default settings. Disable NAT only if you plan
to manually administer the IP address space on the LAN side of the modem router.
