Dynamic mapping in use, cannot remove

hostname#config t
Enter configuration commands, one per line.  End with CNTL/Z.
hostname(config)#int fa0/0
hostname(config-if)#no ip nat inside
hostname(config-if)#exit
hostname(config)#no ip nat inside source list 100
%Dynamic mapping in use, cannot remove

I want to change an access list.  Access list 100.  But I have to drop it first.  But I have to stop using it first (in the inside source list).

How?

Do a "show ip nat translation" to see what NAT entries exist or try:

clear ip nat translation *

Use the "clear ip nat translation" command after the "no ip nat inside" command, then try making your change.

I tried that, but it demands more parameters.  Source & Destination.
