3Com MSR 50, MSR 30 manual Natpt aging-time

869

Note that:

■ If start-ipv4-address equals end-ipv4-address, only one address is available in the address pool.

■ The execution of the undo natpt address-groupcommand may affect some dynamic NAT-PT mappings.

■ Currently, 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 is applied 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 applied to dynamic NAT-PT mapping is the number of configured addresses minus 1.

Example # Configure a NAT-PT address pool.
