Service Name: This item is for identification purposes. If it is required, your ISP will provide you the information.
Maximum input is 15 alphanumeric characters.
NAT: The NAT (Network Address Translation) feature allows multiple users to access the Internet through a
single IP account, sharing a single IP address. If users on your LAN have public IP addresses and can access
the Internet directly, the NAT function can be disabled.
IP (0.0.0.0:Auto): Specify IP addresses that are allowed to logon and access the router's web server..
Note: IP 0.0.0.0 indicates all users who are connected to this router are allowed to logon to the device and modify data.
Auth. Protocol: Default is Chap (Auto). Your ISP will advise you whether to use Chap or Pap.
Connection:
Always on: If you want the router to establish a PPPoA session when starting up and to automatically
re-establish the PPPoA session when disconnected by the ISP .
Connect on Demand: If you want to establish a PPPoA session only when there is a packet
requesting access to the Internet (i.e. when a program on your computer attempts to access the Internet).
Idle Timeout: Auto-disconnect the broadband firewall gateway when there is no activity on the line for a
predetermined period of time.
Detail: You can define destination port and packet type (TCP/UDP) information that will not result in the
router checking the timer. It allows you to set which outgoing traffic will not trigger and reset the idle timer.
MTU: Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers) that IP will
attempt to send through the interface.
RIP: RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
TCP MSS Clamp: This option helps to discover the optimal MTU size automatically. Default is enabled.
Obtain DNS: A Domain Name System (DNS) contains a mapping table for mapping between Domain Names
and IP addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as
www.helloworld.com as well as an IP address. An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx,
for example 10.0.0.2. You can think of an IP address as a telephone number for devices on the Internet, and the
DNS will allow you to find the telephone number for any particular domain name. As an IP Address is hard to
remember, the DNS converts the friendly name into its equivalent IP Address.
You can obtain a Domain Name System (DNS) IP address automatically if your ISP provides it when you logon.
T o use this automatically supplied DNS check the Enable box.
Primary DNS: Enter the primary DNS.
Secondary DNS: Enter the secondary DNS.
