ER605 v1 WAN port assigns itself 192.168.100.11
I have an ER605 switch configured for load balancing WAN and WAN/LAN1 with internal IP address 192.168.0.1 assigned as a gateway.
The switch's DHCP server is assigning static IP addresses to two local LAN devices:
UDM Pro 192.168.0.2
Omada Controller running on RPI4 with 192.168.0.3.
All ports from WAN and WAN/LAN1 are forwarded to UDM Pro. (don't know if this matters)
On occasion, I notice that the WAN port connection to my ISP will drop, auto assigns itself an IP (192.168.100.11) and stays that way even after reboot/disconnecting-connecting via the controller remotely.
Unless I force reset cable modem leading to the WAN it never gets reassigned to a public facing IP address as it should.
Is there something special about 192.168.100.11? Why is it assigning itself that IP address?
