I set up DDNS for WAN1 and WAN2 with the same host name. Somehow, if my main connection (WAN1) goes down, it doesn’t update to WAN2 IP address automatically. I am using priority algorithm with WAN1 and WAN2. Is there anything i should do to trigger IP update automatically when either WAN1 or WAN2 goes down? I have DDNS service with no-ip.com.
