IP Nat source list removal

[brian2112]

I have this in my Router config:

ip default-gateway 216.171.145.17
ip nat inside source list 10 interface Serial1/0.16 overload
ip nat inside source list 20 interface Serial1/1.16 overload
ip nat inside source list 30 interface Serial1/0.16 overload

I need to remove: ip nat inside source list 30 interface Serial1/0.16 overload

however, when I type: no ip nat inside source list 30 interface serial1/0.16

I get this message: %Dynamic mapping in use, cannot remove

how can I remove this line???

in global( config T) type this

No ip nat inside source list 30 interface Serial1/0.16 overload

This will remove the statement. It seems to me that you have already tried this and the erroe appears, is that correct?

This is a blatant fault in cisco's nat implementation.
(Which has never been very flexible IMHO)

Yes, that is right. I have tried that entry, that's when I get the error

Did you look at the url guy?
That has the problem description and "fix".
