Scenario: Connect your iSeries server to a PPPoE access concentrator

Situation

Your business requires a faster Internet connection, so you are interested in a digital subscriber line (DSL) service with a local ISP. After an initial investigation, you find that your ISP uses PPPoE to connect its clients. You need to use this PPPoE connection to provide high-bandwidth Internet connections through your iSeries server.

Solution

You can support a PPPoE connection to your ISP through your iSeries server. The iSeries server makes use of a new PPPoE virtual line type which is bound to a physical Ethernet line configured to use a type 2743, 2760, 2838, 2849, 287F, 5700, 5701, 5706, 5707, or 573A Ethernet adapter. This virtual line supports PPP session protocols over an Ethernet local area network (LAN) connected to a DSL modem which provides the gateway to the remote ISP. This allows LAN connected users to have high-speed Internet access using the iSeries servers PPPoE connection. After the connection between the iSeries and the ISP has started, individual users on the LAN can access the ISP over PPPoE, using the IP address allocated to the iSeries server. To provide additional security, filter rules can be applied to the PPPoE virtual line to restrict certain inbound Internet traffic.

Sample configuration

1. Configure the connection device for use with your ISP.
2. Configure an Originator Connection Profile on your iSeries server.
   Ensure that you enter the following information:

   • Protocol type: PPP
   • Connection type: PPP over Ethernet
   • Operating mode: Initiator
   • Link configuration: Single line
3. On the General page of the New Point-to-Point Profile Properties, enter a name and description for the originator profile. This name refers to both the connection profile and the virtual PPPoE line.
4. Click Connection to open the Connection page. Choose the PPPoE virtual line name that corresponds to the name for this connection profile. After you select the line, iSeries Navigator displays the line properties dialog.
   1. On the General page, enter a meaningful description for the PPPoE virtual line.
   2. Click Link to open the Link page. From the Physical Line Name select list, select the Ethernet line that this connection will use, and click Open. Alternately, if you need to define a new Ethernet line, type the line name and click New. iSeries Navigator displays the Ethernet line properties dialog.
      Note: PPPoE requires a type 2743, 2760, 2838, 2849, 287F, 5700, 5701, 5706, 5707, or 573A Ethernet adapter.
      1. On the General page, enter a meaningful description for the Ethernet Line, and verify that the line definition is using the required hardware resources.
      2. Click Link to open the Link page. Enter the properties for the physical Ethernet line. Refer to the documentation for your Ethernet adapter and the online help for more information.
      3. Click Other to open the Other page. Specify the level of access and authority other users might have for this line.
      4. Click OK to return to the PPPoE virtual line properties page.
   3. Click Limits to define properties for LCP authentication, or click OK to return to New Point-to-Point Profile Connection page.
   4. When you return to the Connection page, specify the PPPoE server addressing based on information provided by your ISP.
5. If your ISP requires the iSeries server to authenticate itself, or if you want the iSeries to authenticate the remote server, click Authentication to open the Authentication page.
6. Click TCP/IP Settings to open the TCP/IP page, and specify the IP address handling parameters for this connection profile. The setting to be used should be provided by your ISP. To allow LAN attached users to connect to the ISP using the IP addresses allocated to the iSeries server, select Hide addresses (Full masquerading).
7. Click DNS to open the DNS page, enter the IP address of the DNS server provided by the ISP.
8. If you want to specify the subsystem to run the connection job, click Other to open the Other page.
9. Click OK to complete the profile.
