EMC® VNX® Series Security Configuration Guide for VNX

Unisphere client/server and NAT

Network address translation (NAT) rewrites IP packet source and/or destination addresses as the packet passes through a router. The main use of NAT is to mask internal hosts from an external network. This may be for security purposes or to allow many internal hosts to have class C IP addresses and masquerade under a single external IP address. NAT can be troublesome for many communication protocols, including those that the Unisphere tools use.

Unisphere Client/Server supports managing a single storage system through a NAT gateway. Only that one storage system will be visible. Domains are not supported as that would require the user to enter the NAT address for every node in the domain.

NAT connections are not supported when Unisphere is launched directly from the storage system or with other tools such as CLI and Unisphere Service Manager.
