The existing entries which have already been created, are not affected. - It may occur after a number of NAT entries are created by traffic flow which goes through from outside to inside. - When this problem occurs, the "misses" counter increase in "show ip nat statistics". - You can observe that the following debug message is output when using "debug ip nat detailed" "NAT: failed to allocate address for XX.XX.XX.XX" - The NAT entry does not depend on TCP/UDP. - It does not depend on a type of interface and platform.
