Service Name: This item is for identification purposes. If it is required, your service provider will provide you
the information. Maximum input is 20 alphanumeric characters.
IP Address: specify if the Gateway can get an IP address from the service provider automatically. Please
click Obtain an IP address automatically via DHCP client to enable the DHCP client function or click Specify
an IP address to disable the DHCP client function, and specify the IP address manually. Your service
provider specifies the setting of this item.
Authentication Protocol: Default is Chap (Auto). Your ISP will advise you whether to use Chap or Pap.
Connection:
Always on: If you want the gateway to establish a PPPoE session when starting up and to
automatically re-establish the PPPoE session when disconnected by the ISP.
Connect on Demand: If you want to establish a PPPoE 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 the destination port and packet type (TCP/UDP) without checking by timer. It
allows you to set which outgoing traffic will not trigger and reset the idle timer.
RIP: RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
MTU: Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers)
that IP will attempt to send through the interface.
TCP MSS Clamp: This option helps to discover the optimal MTU size automatically. Default is enabled.
DNS
A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. In the
Internet world, every host has a unique and user-friendly name (domain name) such as
www.helloworld.com and an IP address. An IP address is a 32-bit number in the form of
xxx.xxx.xxx.xxx , for
example 192.168.1.1. 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 name entered into its equivalent IP Address.
