Cisco Router Delete Static Entries

Cisco 870 Remove port forward error - Static entry in use, do you want to delete child entries?

You need to type "yes" to remove the static NAT entry completely from the configuration.

The "Static entry in use, do you want to delete child entries? [no]:" message simply means that a NAT entry for this rule has not timed out yet or may still be in use. If you want to remove the static entry, type yes and it will remove the entry from the configuration as well as the NAT entries pertaining to it when you do a "show ip nat translation".

The alternative is doing a "clear ip nat translation *" and then removing the static NAT entry but this will remove all entries in use, not just the ones pertaining to the NAT rule you want to remove.
