7. NAT should remain enabled. If you disable NAT, you not be able to use more than one computer for

Internet connections. NAT is enabled and disabled system-wide, therefore if you are using multiple virtual

connections, NAT will disabled on all connections.

8. The Firewall should remain enabled for most users. If you choose to disable this you will not be able to

use the features configured in the Firewall and Filters menus located in the Advanced directory. See the

next chapter for more details on these menus.

9. Typically the globally IP settings (i.e. IP address for the WAN interface) for a PPPoA or PPPoA connection

will use Dynamic IP assignment from the ISP. Some accounts may be assigned a specific global IP

address. If you have been give an IP address for you PPPoE/PPPoA connection, select the Static IP

option from the IP Control pull-down menu. This menu can be used to configure the WAN port as an

Unnumbered IP interface. (See table below for Unnumbered IP)

10. Most users will not need to change ATM settings. If this is the first time you are setting up the ADSL

connection it is recommended that you leave the Service Category settings at the default values until

you have established the connection. See the table on page האיגש !תרדגומ הניא הינמיסה. for a description of

the parameters available for ATM traffic shaping.

11. When you are satisfied that all the WAN settings are configured correctly, click on the Apply button.

PPPoE/PPPoA

Parameters

Description

User Name

For PPP connections, a User Name and Password are used to identify and verify your

account to the ISP. Enter the User Name for your ADSL service account. User names and

passwords are case-sensitive, so enter this information exactly as given to you by your

ISP.

Password

Together with the User Name, this is used to verify your account to the ISP. Enter the

Password exactly as given to you by your ISP.

Connection

Type

This specifies the protocol (PPPoE or PPPoA) and the encapsulation method (LLC or

VC-MUX) used for your connection. The options available are PPPoE LLC, PPPoA LLC

or PPPoA VC-MUX.

MRU

Maximum Received Unit size for downloading data. Most users will be happy with the

default setting (1492 bytes). However this may also be optimized for fast downloads of

general bulk Internet traffic, for low latency or for downloading to computers on the

Wireless LAN. As with the MTU setting, the user should carefully consider how changing

the MRU may effect Internet downloads for all systems on your LAN.

Authentication

This allows you to choose the protocol the router will use to communicate your Username

and Password for your Internet account. PAP and CHAP are both supported. Your ISP

should provide you with the correct choice.

Obtain DNS

Automatically

This allows you to specify if the router will use the DNS server address supplied by your

ISP or if it will use a DNS server address you supply under the DNS directory.

Default Route

When this is enabled, the Router will be considered to be the primary gateway to the

Internet and WAN for systems on your network. If you are using the Router on a network

with one or more alternative gateway routers, you may prefer to disable this if you will use

another router as the primary gateway.

NAT

Network Address Translation may be enabled or disabled with the pull-down menu. Keep

in mind that disabling NAT allows on a single computer to be used for Internet access

through the Router. NAT is enabled and disable for the Router on all connections (i.e.

Pvc0 – Pvc7) if your Router is set up for multiple virtual connections.

IGMP

Enabled/Disabled − this enables or disables IGMP (Internet Group Management

Protocol) on the router. This should normally be enabled.
