<![CDATA[OpenDNS updates for multiple WANs - specifying the sending interface?]]>I have two WAN connections (Both dynamic IPs) that I load balance. I use OpenDNS and need to provide Dynamic IP updates for both WANs. I have the Dynamic DNS service configured for both interfaces in pfSense. Interface 1 works great but interface 2 is rejected by OpenDNS with an error that the IP update has to come from the actual interface and not a different IP. Can I configure pfSense to send the Dynamic IP updates using the interface that the IP update is for?

Thanks!

If you would use different DynDNS services for the interfaces you could add a static route for the one which is not using the default gateway.
But when you are using the same update servers on both interfaces you can only do a workaround with a custom client. In custom setup you can state the "Interface to send update from" to use the proper one.
