kindly advice

Are you sure your syntax is really as above?

PAT works best when specifying an interface instead of a pool. Please try to use:

ip nat inside source list 10 interface vlan 179 overload as in:

Hi Leo,

just a quick note to say that when specifying the interface in NAT overload the overload keyword is automatically added by the IOS in the configuration so there's no need to specify it.

Yes, I know that but I was triggered by overloaded instead of overload and ip nat nat pool nat_pool where, IMHO, there is a keyword too many. This output was not gathered from the CLI, probably just quickly typed without checking.

Pleae draw your own conclusions.

Hi Leo,

No harm intended    this was just a remark for the OP but as you had proposed the statement that's why I answered you.

I draw no conclusions different from you.

Hi

Thanks to all for replying and sorry about spelling mistake as it was typed in urgency.

I use interface also but not working.It may be a bug on IOS

Perhaps if you can share the output of sh ver and sh module  with us, we can say anything about that.

regards,

Leo
