5. Routed Mode WanLink with WanPaths

Goal: Setup a Routed Mode WanLink with WanPaths. Return to LANforge-ICE Cookbook

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.

    A: Go to the Status tab and click Netsmith
    B: Right-click in the Netsmith window and select New Connection
    C: Accept defaults, Auto Create everything and click OK
    D: Click Apply in the Netsmith window to create the connection
    E: The Netsmith window after applying changes

  2. Setup the WanLink.

    A: Right-click the WanLink and select Modify WanLink
    B: Setup the WanLink with values larger than what each of the WanPaths will use

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

    • Click Apply and leave the Create/Modify WanLink window open

  3. Setup the WanPaths.

    A: Click Create-WP on Entry Point A to create a new WanPath on this WanLink

    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

    • Click OK to create the WanPath

    B: Click Create-WP on Entry Point B to create a new WanPath on this WanLink

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

    • Click OK to create the WanPath

    C: Create a second WanPath for this WanLink using the next set of IP addresses
    D: Reverse the Source and Destination IPs for this corresponding WanPath
    E: Verify that the WanPaths on this WanLink are setup correctly, then click OK on the Create/Modify WanLink window shown here

  4. Setup the ports with IP addresses.

    A: Right-click on the WanLink and select Toggle Wanlink
    B: Right-click port rddVR0 and select Modify Port
    C: Setup an IP address that is on a different network than the WanPath entry points
    D: Setup an IP address on port rddVR1 that is on the same network as rddVR0

  5. Add the Virtual Routers.

    A: Right-click in the Netsmith window and select New Router
    B: Accept the defaults or change the Virtual Router name and graphical size
    C: Click the Apply button and repeat for the second Virtual Router

    NOTE:   After making any changes to the Netsmith window, you must click Apply or your changes will NOT be implemented and could be lost

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

    D: Left-click rddVR0 and drag it inside Router R0(1)
    E: Left-click rddVR1 and drag it inside Router R1(2)
    F: Apply your changes in Netsmith

  6. Setup the external interfaces.

    A: Right-click port eth0 and select Modify Port
    B: Setup eth0 with a valid IP address and IP mask that is on the same network as the WanPath entry points ep-1 and ep-3
    C: Left-click port eth0 and drag it inside Router R0(1)
    D: Setup eth1 with a valid IP address and IP mask that is on the same network as the WanPath entry points ep-2 and ep-4
    E: Drag eth1 inside Router R1(2) and Apply changes in Netsmith

  7. Run traffic to LANforge-ICE ports eth0 and eth1, then display results. Refer to the LANforge FIRE Cookbook to run traffic.

    A: Right-click the WanLink and select Display Wanlink
    B: The lower half of the WanLink display shows traffic passing on WanPath entry points ep-3 and ep-4 and other IP address are excluded from passing on the WanLink
    C: Select a WanPath and click Display Selected Paths in the lower left corner of the WanLink display window
