On Accessing Unisphere, NAT IP was used leading to error "Forbidden Untrusted hostname"   
     
                                                           

 

 

Cause:

 

 

NAT IP was used instead of local management IP.                                                           

 

 

Resolution:

 

 

Single sign-on does not support a NAT configuration. Also, NAT is not supported for local login through Unisphere to the storage system.
