Recently our mangement IPS changed from extenal (Public IP) to Internal (Private IP) since connectivity was established through MPLS. I wanted to update the NAS IP from public to private IP interface. However what i found through FW GUI that in the drop down it does not give me the option to select from the Firewall interfaces. It is showing wrong interface IPs.
I also tried to change the NAS IP through GUI but it is giving me an error as below and i am unable to set the interface address.
"NMSAAA9999 Invalid NAS IP address x.y.z.w" cannot set as NAS IP .
FW version is 80.20
Please help.
