Router Connection

To properly configure your Internet connection, type the IP addresses for the Domain Name System (DNS) servers at your Internet service provider (ISP) and the local IP address of your router.

If your router connection to the Internet requires a user name and password, you must configure the Point-to-Point Protocol over Ethernet (PPPoE) settings on your router.

Important

  • In addition to the configuration settings performed by this wizard, you must follow your ISP's instructions for connecting your router device to the Internet.

 

Item Description

Preferred DNS server

Type the IP address of DNS server at your ISP. The DNS Server service provided with Windows Small Business Server 2003 will be configured to forward the DNS queries it cannot resolve to the DNS server you specify.

Note

  • If you do not specify DNS server information, name resolution requests must instead use root hints. It is recommended that you use DNS server information if it is available from your ISP. For more information, click Start, click Help and Support, and then search for "root hints."

Alternate DNS server

If your ISP provides a secondary DNS server to use for backup DNS name resolution across the Internet, type the IP address. This option can be left blank. The IP address of the alternate DNS server cannot be the same IP address as the preferred DNS server you specified.

Local IP address of router

Type the IP address of the router interface used to connect to the local network, as shown in Figure 1. This IP address is used to configure the default gateway.Local IP address of router

My server uses a single network connection for both Internet access and the local network

Specifies that your server uses only one network adapter to connect to both your ISP and the local network.

If the server uses one network adapter, the local router is the gateway to the Internet, as shown in Figure 2.

In this configuration, the firewall provided with Windows Small Business Server 2003 cannot be used to secure your local network from unauthorized Internet access.

To secure your local network, you must use a firewall device on the network. If the firewall device supports the UPnP framework, you can still use the Configure E-mail and Internet Connection Wizard to configure firewall settings on the device. If the device does not support the UPnP framework, you must manually configure the settings. For more information about the settings, see Appendix C, "Network Configuration Settings," of Getting Started.

Important

  • If your router connection to the Internet requires PPPoE settings, you must manually configure these settings on the router, even if the device supports the UPnP framework.
