~

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.

Advanced Options (PPPoA)

LLC Header:

Selects encapsulation mode, true for using LLC or false for using VC-Mux.

Create Route:

This setting specifies whether a route is added to the system after IPCP (Internet Protocol

Control Protocol) negotiation is completed. If set to

enabled

, a route will be created which directs packets

to the remote end of the PPP link.

Specific Route:

Specifies whether the route created when a PPP link comes up is a specific or default

route. If set to

enabled

, the route created will only apply to packets for the subnet at the remote end of the

PPP link. The address of this subnet is obtained during IPCP negotiation.

Subnet Mask:

sets the subnet mask used for the local IP interface connected to the PPP transport. If the

value

0.0.0.0

is supplied, the netmask will be calculated from the class of the IP address obtained during

IPCP negotiation.

Route Mask:

Sets the subnet mask used by the route that is created when a PPP link comes up. If it is

set to

0.0.0.0

, the subnet mask is determined by the IP address of the remote end of the link. The class of

the IP address is obtained during IPCP (Internet Protocol Control Protocol) negotiation.

MRU:

Maximum Receive Unit. This is negotiated during the LCP protocol stage.

Discover Primary / Secondary DNS:

This setting enables/disables whether the primary/secondary DNS

server address is requested from a remote PPP peer using IPCP. The default setting for this command is

enabled

.

Give DNS to Relay:

Controls whether the PPP Internet Protocol Control Protocol (IPCP) can request the

DNS server IP address for a remote PPP peer. Once IPCP has discovered the DNS server IP address, it

automatically gives the address to the local DNS relay so that a connection can be established.

Give DNS to Client:

Controls whether the PPP Internet Protocol Control Protocol (IPCP) can equest a

DNS server IP address for a remote PPP peer. Once IPCP has discovered the DNS server IP address, it

automatically gives the address to the local DNS client so that a connection can be established.

Give DNS to DHCP Server:

Similar to the above, but gives the DNS server address to the DHCP server.

Discover Primary NBNS / Discover Secondary NBNS:

This setting enables/disables whether the

primary/secondary NBNS server address is requested from a remote PPP peer using IPCP. The default

setting for this command is disabled.

Discover Subnet Mask:

Specifies if the subnet mask given by IPCP negotiation process is to be used.

Give Subnet Mask To DHCP Server:

Enable to change your DHCP Server settings by using the given

information in IPCP negotiation process.

IP Assignment

~

Obtain an IP address automatically via DHCP client:

specify if the Router can get an IP

address from the ISP (Internet Service Provider) automatically.

Use the following IP Address:

Specify the IP address manually; the IP should be given by you

our ISP.

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.

client function or click Specify an IP address to disable the DHCP client function, and specify the IP

address manually. The setting of this item is specified by your ISP.

Authentication 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 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.
