R2511-HP MSR Router Series Layer 3 - IP Services Command Reference(V5)

187
The execution of the undo natpt address-group command might affect some dynamic NAT-PT mappings.
A NAT-PT address pool and an IPv4 NAT address pool do not share any address.
When there is only one address in the NAT-PT address pool, the address applies to only NAPT-PT. When
there is more than one address in the NAT-PT address pool, the end IPv4 address is reserved for NAPT-PT.
The number of addresses used for dynamic NAT-PT mapping is the number of configured addresses
minus 1.
