Rockstor 5.0.14-0
Removed 10G fiber optic card and connected to 1G RJ45 onboard LAN socket. Started setup and Rockstor reported OLD IP of 192.168.1.106. Could not connect, so logged in as root and typed myip and it reported 192.168.1.102 which is what it should have reported after restart.
PS: Switched from LAN 0 to LAN 1 on motherboard and got same result. Reinstalled 10G card and got same result.
