WAN Affinity rules allow you to manage traffic in your network so that particular bandwidth users are associated with particular WAN sources.  This allows you to prioritize bandwidth.  This article explains the steps needed to configure WAN Affinity on a capable Series 3 CradlePoint.


  1. Log into the router’s Setup Page.  For help with logging in click here.
  2. In the tabs across the top click on Internet.  Then click on WAN Affinity/Load Balancing.                                                             User-added image
  3. In the box labeled Affinity Rules, click Add.                                                                                                                                                User-added image
  4. Give your rule a unique name.
  5. Enter the DSCP.  Differentiated Services Code Point is the successor to TOS (type of Service).  Use this field to select traffic based on the DSCP header in each IP packet.  This field is sometimes set by latency sensitive equipment such as VoIP phones.  For more information see the Differentiated Services Wikipedia page.
  6. Check the DSCP Negate box if you want the rule to apply to any packet that does not match the DSCP field.
  7. Choose the protocol you wish the rule to apply to.
  8. Source and/or Destination IP addresses: Specify an IP address or
    range of IP addresses by combining an IP address with a netmask for either ―source‖ or ―destination‖ (or both). Source vs. Destination is defined by traffic flow. Leave these blank to include all IP addresses (such as if your rule is defined by a particular port instead).
  9. Destination Port(s): Enter a port number between 1 and 65535. To enter a single port number, input the number into the left box. To enter a range of ports, fill in both boxes separated by the colon. For example “80:90” would represent all ports between 80 and 90 including 80 and 90 themselves.
  10. Check the Failover box if when your chosen WAN interface looses its connection, normal failover will apply and traffic will be directed to the highest priority WAN connection. If it is unchecked and the WAN devices looses its connection, all traffic will stop even if another WAN connection exists.
  11. Configure the WAN Binding Type base on your needs.  You have several options for specifying the type of WAN interface(s) you want associated with your rule. Designate the interface(s) by Port, Manufacturer, Model, Type, Serial Number, MAC Address, or Unique ID. This selection will create a dropdown list of options to complete a sentence with the following form: ―When ____ is ____,‖ such as, ―When Port is  Blue Ethernet.‖ You also have the option to replace ―is‖ with ―isn‘t,‖ ―starts with,‖ ―ends with,‖ or ―contains.‖
          Port: Select from the dropdown list of possible WAN ports on the router.
               o Blue Ethernet

               o USB 1
               o USB 2
               o USB 3
               o ExpressPort 1
               o ExpressPort 2
          Manufacturer: Select from a dropdown list of attached devices
     Model: Select from a dropdown list of attached devices.
          Type: Select from the dropdown list of possible WAN types.
               o WiMAX

               o Ethernet
               o Wireless As WAN
          Serial Number: Select from a dropdown list of attached devices.
          MAC Address: Select from a dropdown list of attached devices.
          Unique ID: Select from a dropdown list of attached devices.
