Other types of NAT have restrictions such as the sending IP address must initially have

had packets sent from the private IP address and port regardless of the external port, or

from the private IP address and the external port.

must be checked for Fullcone NAT to be used.



Dial on demand

: When this mode is selected, the connection that has no traffic within

assigned disconnect timeout (e.g. 1 minute) will be automatically disconnected. The

connection will be activated again when traffic arrives. This function is advantageous for

users who are charged with online time. It should be noticed that some programs

automatically link to Internet. Computer will send data to network when infected by virus.

Connection will not be disconnected under these data streams.



Inactivity Timeout

: When

“

Dial on demand

”

is selected, this input box indicates that

after how long the connection will be disconnected in the absence of traffic. If the value is

0, connection will not be disconnected.



Enable manual MTU set

: the Maximum transmission unit (MTU) value may be set for

your needs. Higher MTU can provide for a more efficient link because each packet will

carry more data while the overhead in the packet such as header information does not

get larger with the size of the packet. So the bulk throughput on the link will go up.

Generally a large packet size can occupy the time on the link, so the higher MTU can

increase lag time and minimum latency which is not appropriate for all applications.



Manual Connect

: connect/disconnect PPPoE connection manually



Enable NAT

: To define NAT services in the

Advanced Setup | NAT

screens, NAT must

be enabled.



Enable Firewall

: Enables Firewall.



Use Static IPv4 Address

: Defines a static IP address (v4) which you enter in the

IPv4

Address

text box which is displayed when the

Use Static IPv4 Address

check box is

selected.



Enable PPP Debug Mode

: Used to debug PPPoE issues. Use only when instructed by

your ISP.



Enable KeepAlive

: Enables/disables TCP keep alive packets



Enable IGMP Multicast Proxy

: Configures the router for IGMP snooping so the router

can keep limit multicast traffic.



Enable Fullcone NAT

: RFC 3489 defines four types of Network Address Translation

(NAT). Fullcone NAT. As with other types of NAT there is a mapping from a public IP

address to a private IP address. The external public IP address is extended with the

external port. With Fullcone NAT once the mapping is created any external host may

send packets to the private IP address by sending to the external IP address and port.

Other types of NAT have restrictions such as the sending IP address must initially have

had packets sent from the private IP address and port regardless of the external port, or

from the private IP address and the external port.

LAN Local Area Network (LAN) Setup

You can configure the DSL Router IP address and Subnet Mask for the LAN interface to

correspond to your LAN‘s IP Subnet.

.Changing the IP address here may cause your browser to

be disconnected from the modem.

You will need to set your PC to the same subnet as the

modem

‘s

IP address to access the router again.

IGMP snooping

If you want the DHCP server to automatically assign IP addresses, then enable the DHCP server

and enter the range of IP addresses that the DHCP server can assign to your computers. Disable

the DHCP server if you would like to manually assign IP addresses.

Default

–the default LAN configuration is based on your router‘s IP address.

Static IP Lease

list

–

you can configure the DHCP server to set aside up to 32 static IP

addresses based on the MAC addresses of the device connected to the router by clicking on the

add entries button.

To remove the Static IP address, click the check box next to the MAC address and click

Remove

Entries

You may be able to assign a second IP address for the modem.

To do that, click the check box
