Hi,

NAT is not supported on the 3750s. Here is a link that confirms that:

what about GSR?

Re: how to do NAT on cat 3750 switch?

NAT is not supported on 3550, 3560, nor 3750. There is no plan to support NAT in future IOS release due to hardware limitation.

does the GSR support this feature?

Re: how to do NAT on cat 3750 switch?

Yes, the GSR would definittely support NAT, as a matter of fact any router will support NAT.
