I want to add a static NAT in 3650 switch. I tried it but I couldn't find static NAT ('ip nat inside source static' command is not there). I added a dynamic NAT using ACL. I want to change change 1.1.1.1:99 to 2.2.2.2:99 so I only put 1.1.1.1 in the ACL. But when I apply NAT it didn't translate. If I allow all in ACL I could see inside ip interface of the switch is being translated to outside ip interface with PAT.
My configuration
Interface vlan 100
ip address 1.1.1.2 255.255.255.0
ip nat inside
Interface vlan 200
ip address 2.2.2.2 255.255.255.0
ip nat outside
ip nat inside source list NAT-list interface vlan 200
Can we do this kind of NAT in this switch?
I cannot find 3650 in cisco NAT support matrix.
Is there any issue in my configuration?
Thanks

Hi
Unfortunately the switches do not support NAT configuration, you need a router to use NAT.

Hi Julio,
Thank you very much for your explanation. However this is a L3 switch with IP base licence. So do you think this will support NAT?
Also some NAT commands are available in the cli

NAT is not and will never be supported in Catalyst switches. NAT function is the exclusive domain of routers.
The commands maybe there but they won't function.
