# PPP over Ethernet Configuration Guide

## Installation

Using PPP over Ethernet requires additional installation - you must attach SafeFire Links to your network card. This can be done in the following steps:

1. Run Multi-Protocol Transport Services by either clicking on "Adapters and Protocol Services" () icon in the System Setup folder or starting "mpts.exe" from the command line.
2. You must see following window:

Click on "Configure"

3. Configure window will appear:

Again click on "Configure"

4. The following window is named "Adapter and Protocol Configuration":

You must see you Ethernet Adapter listed instead of D-Link adapter. If you have multiple adapters, select the adapter that will be configured for PPP over Ethernet support.

Note: In general case you don't need to have IBM TCP/IP protocol bound to the adapter prepared for use with PPP over Ethernet to make PPP over Ethernet function properly. But in some cases it might be needed to have TCP/IP bound to same adapter anyway.

5. Select "Other protocols" and enter "D:\SFLINKS\NDIS" (where D:\SFLINKS is the path where SafeFire Links was installed) in the "Copy Additional Protocols" window and press OK:

6. You must be returned to "Adapter and Protocol Configuration" and it's Protocols list be updated with SafeFire Firewall Protocol entry:

Select this entry if it is not selected and click "Add"

7. The protocol must be added under your adapter. You need to set its logical number to 0 (1 for second instance and so on):

8. Now, when configuration is finished, press "OK" button in the "Adapter and Protocol Configuration" window, then "Close" in the "Configure" window and "Exit" in the "Multi-Protocol Transport Services" main window.
9. You will be asked if you want to update your config.sys file:

Check if your boot drive is highlighted in the list (highlight it if it is not) and press "Exit"

10. When your config.sys will be updated, you will be notified. Close the window by pressing "Ok". "Exiting MPTS" window will appear:

Press "Exit" to exit the program and restart your computer. Now your PC is ready for PPP over Ethernet. Check Up and Running book to select needed configuration file and start your Internet connection.

## Tips and Tricks

Some providers may require special settings to get PPP over Ethernet working. Next list will show you know questions and answers:

- Q: I can not start PPP over Ethernet. Something is wrong with authentication.
- A: Check if you correctly entered your user name and password into the configuration.file If all is OK, try adding provider's domain name after your user name.

Example: If my username is "john" and I am using Bell Sympatico provider, I will set auth.client.username to "john@sympatico.ca".
