Single IP address in a source NAT pool without PAT

This feature allows you to configure a single IP address in a source NAT pool with no Port Address Translation (PAT), and enables you to use two new options: address-shared and address-pooling (paired or no-paired). The number of hosts that a source NAT pool with out PAT can support is limited to the number of addresses in the pool. When you have a pool with a single IP address, only one host can be supported, and traffic from other hosts is blocked, because there are no resources available. If a single IP address is configured for a source NAT pool without PAT when NAT resource assignment is not in active-backup mode in a chassis cluster, traffic through node 1 will be blocked
