Port8 WAN Failover DHCP (its a 4G cradlepoint) set as Backup in Link Manager.

For example, if your…
For example, if your XG has the Public IP 184.108.40.206 and your ISP router (DG) is 220.127.116.11, the XG will be Pining only that IP, so if your ISP has any issue beyond this router, the XG won’t consider the link down, as the ISP router will still be replying back, but if you use a Public IP such as 18.104.22.168 the XG will be testing the connectivity all the way beyond your ISP Router.
XG -->> ISP
XG -->> ISP -->> Beyond
Great! I was missing the obvious. Thank you.
