Trying to use nat with Catalyst 1000 Series

[RT74693]

Hi everyone,

I'm  trying to use nat on a catalyst 1000 Series.

I've configured 2 vlan; one with ip nat inside and another with ip nat outside.

I've configured an acl as well.

Nat do not work, when i'm using wireshark i see outcoming packets source with the internal address.

NAT's tables seems to be empty.

to resume :

interface Vlan 100

ip address 10.1.112.61/27

ip nat inside


interface Vlan 200

ip address 172.16.10.64/255

ip nat outside

access-list 100 permit tcp any any

ip nat inside source list 100 interface Vlan 200 overload

If someone could help or explain to me how to do?

May be catalyst 1000 series could not provide NAT features?

Thanks

Cat 1000 is switch, i do not believe this support NAT feature here. you need Router to do this task .

or is this Router  ISR 1000 ?

Can you post show version and show run

Hello @RT74693 ,

Catalyst 1000 should not support NAT.

However, whati s misleading the CLI parser is "unified" for IOS XE so you can see commands that actully are not supported in your platform.

As already suggested by BB for NAT you need a router like an ISR

Hope to help
