Chapter 6. Installing And Configuring Your SME Server V5 with ServiceLink Software
What is PPPoE?
PPPoE is the Point-to-Point Protocol over Ethernet . Essentially, it is an implementation of the popular PPP protocol used for dialup connections
- only configured to run over an Ethernet connection. Many ISPs that provide ADSL connections use PPPoE as the method of connecting their
customers to the Internet over ADSL.
If you have a static IP address and your ISP does not offer DHCP or PPPoE, then your ISP will give you the static IP address, subnet mask (or
netmask), and the gateway IP address of the device that your server should connect to in order to communicate with the Internet. Assuming you have
this information on hand, you can go ahead and select Option 4. Successive screens will prompt you to enter each parameter.
6.11.4. Configuring Dynamic DNS
If you choose either of the DHCP options or PPPoE, you will be presented with an additional screen where you can choose which dynamic DNS
service you wish to use.
The server is pre-configured to operate with four dynamic DNS organizations: yi.org (http://www.yi.org/), dyndns.com (http://www.dyndns.com/),
dyndns.org (http://www.dyndns.org/), and tzo.com (http://www.tzo.com/). (You can elect to use a different service, but doing so would require some
customization of the server.) Once the service is selected, the subsequent two screens will prompt you to enter your account name and the password
for your account. (These two parameters would be given to you by the service. Note that the dynamic DNS service may place restrictions on which
domain name you can use for your company.) Please read Appendix B on dynamic DNS for more information about whether a dynamic DNS is right
for you.
Tip: ServiceLink subscribers do not need to worry about a dynamic DNS service as DNS service is provided as part of the base ServiceLink
subscription.
6.12. Configuring the Server for Server and Gateway Mode - Dialup Access
If you select dialup access, successive screens will ask you for the following information:
• information regarding the modem or ISDN connection with your ISP, such as the serial port your modem is connected to
1
• modem or ISDN initialization screen - most users can simply leave this blank, but with some particular modems or ISDN cards, additional
information may need to be entered here
• the dialup access phone number
• username
• password
• connection policy
1. Your modem documentation may indicate which serial port is used by the modem. You may also be able to visually identify which port your modem uses.
