To start the Small Business Server Internet Connection Wizard

1. Open the To Do List from the Small Business Server Administrator Console and click Internet Connection Wizard.
2. On the Welcome page, click Next.
3. The Configure Hardware page offers four choices:
   • Modem or terminal adapter. Use when you have an analog modem or ISDN terminal adapter.
   • Router. Use when a DSL/ADSL, ISDN, frame relay, or cable router is used to connect to the Internet.
   • Full-time connection/Broadband Modem. Use for a full-time, high-speed connection to the ISP-for example, when using a DSL/ADSL modem or router or a cable modem.
   • Do not change my networking configuration. Use if the server is not functioning as a gateway between the private network and the Internet. Also use to preserve manually configured network settings.
     • For a Modem connection, click Modem or terminal adapter, click Next, and go to Step 4.
     • For a Broadband connection, click Full-time connection/Broadband Modem, click Next, and skip to Step 5.
4. If you selected Modem or terminal adapter on the Configure Hardware page, the Set Up Modem Connection to ISP page appears. Enter your ISP credential information:
   • Dial-up Connection. Select the dial-up network connection entry used to connect to the ISP. If an entry was previously created, select it. If not, click New to create a new dial-up network connection.
   • ISP account name. Enter the name of the account assigned by the ISP to Small Business Server.
   • Password. Enter the account password, obtained from your ISP.
   • Confirm password. Re-type the account password.
   • I have a static IP address from my ISP with this connection. If you select this checkbox, you will provide an IP address in the IP address field and a DNS server IP address in the Primary DNS server address field.
   Click Next.
5. The Configure Network Adapter page appears.

   For Modem configuration, Configure Network Adapter page will allow you to select only the card to use for the internal network (because you are using a modem for the external network). Select the card (this will be the card with address 192.168.16.2 if you accepted the default when you set up the server). Click Next, and go to Step 6.

   For Broadband configuration, the Configure Network Adapter page requires you to select both the internal and the external cards. After doing so, click Next, and on the Set Up Full-time Broadband Connection page, provide the following information:

   • External Network Adapter. Specify the IP address, subnet mask, and default gateway information for the second network adapter. These fields will be unavailable if you have already configured the network card with static information.
   • Primary DNS server address. Use the primary DNS server IP address provided by the ISP.
   • Secondary DNS server address. Use the secondary DNS server IP address, if available from the ISP.
   Click Next.
6. On the Configure Internet Mail Settings page, you can select the following options:
   • Use SMTP for Internet Mail. Select this option to use SMTP mail through the Exchange Server if you have either a full-time Internet connection that uses SMTP mail or a dial-up connection to the ISP in which e-mail is queued until connecting for delivery.
   • Do not change my Exchange Server settings. This prevents Exchange Server settings from being overwritten by the wizard configuration. Select this option if Exchange Server settings are already configured and you want to retain them.
   • Disable Exchange Server electronic messaging. Select this option when you want to disable Internet mail through Exchange Server. This option retains e-mail exchange between LAN recipients.
   • Use POP3 for Internet Mail. This setting enables retrieval of e-mail from an ISP POP3 mail server instead of an SMTP server.
   • Do not change my POP3 settings. This setting preserves any existing POP3 e-mail settings.
   • Disable POP3 electronic messaging. This setting disables POP3 e-mail.
   You will usually select either Use SMTP for Internet Mail or Do not change my Exchange Server settings, and click Next.
7. On the Configure Internet Domain Name page, enter your domain name in the form of company.com.
   The domain name must be registered with a Domain Name Registry service on the Internet or provided to you by the ISP. If you have a dial-up Internet connection, the entered domain name is configured automatically on the Dial-up Connections tab of the Exchange Server IMS.
8. If you selected Use Exchange Server for Internet mail in the Configure Internet Mail Settings page, the Configure SMTP Server Address page appears.
   • For a non-persistent Modem connection, select Forward all mail to host. This sets Exchange Server to forward all messages to an ISP SMTP relay host.
   • For a full-time connection (such as Broadband), click Use domain name system (DNS) for mail delivery. This enables DNS resolution of Internet e-mail addresses.
9. At the Receive Exchange Mail, you are given mail retrieval options. You will need to contact your ISP to determine whether you need to send a signal.
   • Generally, if you have a full-time connected server (here Broadband) with a static IP address given by the ISP, you will check Do not send a signal, and click Next.
   • For a non-persistent Modem connection, you will need to check Send a signal and determine from your ISP whether to use ETRN command or Issue Turn after Authentication.
10. At the Configure Packet Filtering page, you can provide security for the LAN through an ISA Server firewall, as follows:
    • Enable ISA Server firewall. Enables packet filtering so that LAN users have Internet access through the Web Proxy or Winsock Proxy service. The following packet filters are installed by default:
    • ICMP Ping Echo.
    • ICMP Ping Response.
    • ICMP Source Quench.
    • ICMP Timeout.
    • ICMP Unreachable.
    • ICMP Outbound.
    • UDP DNS.
    If you select only Enable ISA Server firewall without also selecting any of the Small Business Server services described below, LAN users will be able to use the services outbound to the Internet, but inbound requests for these services will be denied. Enable specific services for inbound Internet requests by selecting from the following:
    • My Mail Server (Exchange Server). Enables TCP port 25 (SMTP) on Small Business Server for mail exchange with the ISP's SMTP server.
    • My Web Server. Permits your Web site hosted by Small Business Server to be accessible on the Internet. Allows Small Business Server to listen for Internet requests on TCP ports 80 (HTTP) and 443 (HTTPS), to serve Web pages from Internet Information Server (IIS). The My Web-based Mail Server selection allows access to Exchange Server's Web Client.
    • Virtual Private Networking (PPTP client access). Enables remote clients to connect to Small Business Server over the Internet through Point-to-Point Tunneling Protocol (PPTP). Opens the PPTP call and receive filters (TCP port 1723) so that remote clients can connect to the LAN through a secure tunnel.
    • POP3. Allows Small Business Server to listen to POP3 requests from the Internet on TCP port 110.
    • FTP. Permits Internet users to access the Small Business Server's File Transfer Protocol (FTP) service by allowing the server to listen on TCP ports 20 and 21 for FTP and FTP data, respectively.
    • Terminal Services. Permits Internet users to access Small Business Server Terminal Services.
    • Disable ISA Server firewall. Disables ISA Server protection of LAN security.
    • Do not change firewall settings. Select if you have previously configured ISA Server settings that you do not want changed by the wizard configuration.
    For more information on security settings and how better to secure your network with ISA, refer to chapter 21 of the Small Business Server 2000 Resource Kit, "Firewall Security and Web Caching with Internet Security and Acceleration Server," and to the white paper Microsoft Small Business Server 2000: Understanding and Configuring Internet Security.
11. On the Completion page, review the configuration options, and click Finish.
