Had an interesting issue over the weekend. One of our balances went offline, and we could not get it to ping even after several reboots. I noticed on the display as well, some of our DHCP WAN connections were getting the wrong ip addresses. Ip addresses that the wan to the left of it should be getting. So through experimenting, I figured out, all the ports (Lan and Wan), have shifted to the right one port. So Lan, is now Wan1, Wan1 is now Wan2, and Wan2 is on Wan3 port. The Lan port doesn’t seem to light up with any activity.
My guess is the Lan port died, and the balance saw this and migrated ports to working port? Is this assumption correct, or is some trickery happening?
