Routed Mode WanLink with WanPaths

Goal: Setup a Routed Mode WanLink with WanPaths.

In this test scenario, LANforge-ICE is used to filter traffic by IP address on a WanLink with the use of WanPaths.
 
  1. Setup a Netsmith connection.

    1. Go to the Status tab and click Netsmith screenshot

    2. Right-click in the Netsmith window and select New Connection screenshot

    3. Accept defaults, Auto Create everything and click OK screenshot

    4. Click Apply in the Netsmith window to create the connection screenshot

  2. Setup the WanLink.

    1. Right-click the WanLink and select Modify WanLink screenshot

    2. Setup the WanLink with values larger than what each of theWanPaths will use screenshot

      1. WanPaths are subordinate to WanLinks. WanLinks, therefore, should be configured with sufficient bandwidth and buffering required by all of its WanPaths

      2. Click Apply and leave the Create/Modify WanLink window open

    For more information see LANforge-GUI User Guide: WanLinks

  3. Setup the WanPaths.

    1. Click Create-WP on Entry Point A to create a new WanPath on this WanLink screenshot

      1. NOTE: In order to filter by specific IP address, use a Source and Dest Mask of 32 to exactly match the IP coming in on the Entry Point

      2. Click OK to create the WanPath

    2. Click Create-WP on Entry Point B to create a new WanPath on this WanLink screenshot

      1. NOTE: The Source and Destination IPs for this WanPath are the reverse of those for Entry Point A

      2. Click OK to create the WanPath

    3. Create a second WanPath for this WanLink using the next set of IP addresses screenshot

    4. Reverse the Source and Destination IPs for this corresponding WanPath screenshot

    5. Verify that the WanPaths on this WanLink are setup correctly, then click OK on the Create/Modify WanLink window shown here screenshot

    For more information see LANforge-GUI User Guide: WanLinks

  4. Setup the ports with IP addresses.

    1. Right-click on the WanLink and select Toggle Wanlink screenshot

    2. Right-click port rddVR0 and select Modify Port screenshot

    3. Setup an IP address that is on a different network than the WanPath entry points screenshot

    4. Setup an IP address on port rddVR1 that is on the same network as rddVR0 screenshot

    For more information see LANforge-GUI User Guide: WanLinks

  5. Add the Virtual Routers.

    1. Right-click in the Netsmith window and select New Router screenshot

    2. Accept the defaults or change the Virtual Router name and graphical size screenshot

    3. Click the Apply button and repeat for the second Virtual Router screenshot

      2. NOTE: Clicking Sync makes sure any changes are synchronized with the current database

    4. Left-click rddVR0 and drag it inside Router R0(1) screenshot

    5. Left-click rddVR1 and drag it inside Router R1(2) screenshot

    6. Apply your changes in Netsmith screenshot

    For more information see LANforge-GUI User Guide: WanLinks

  6. Setup the external interfaces.

    1. Right-click port eth1 and select Modify Port screenshot

    2. Setup eth1 with a valid IP address and IP mask that is on the same network as the WanPath entry points ep-1 and ep-3 screenshot

    3. Left-click port eth1 and drag it inside Router R0(1) screenshot

    4. Setup eth2 with a valid IP address and IP mask that is on the same network as the WanPath entry points ep-2 and ep-4 screenshot

    5. Drag eth2 inside Router R1(2) and Apply changes in Netsmith screenshot

    For more information see LANforge-GUI User Guide: WanLinks

  7. Run traffic to LANforge-ICE ports eth1 and eth2, then display results. Refer to the LANforge FIRE Cookbook to run traffic.

    1. Right-click the WanLink and select Display Wanlink & WanPaths screenshot
