    I have a question.

    Currently I have 2 site location and already setup site-to-site tunnel. However, one of the site location (location A) request to do NAT so that the network traffic able to NAT and go to location B by S-S tunnel.

    Is NAT able to work in site-to-site tunnel? If yes, kindly provide the guide or reference to do the configuration. if no, is there any workaround able to done in Aruba controller beside purchase a NAT device.

    Additional info:
    the location A do not use AP. All users are connected to a layer 3 switch and the layer 3 switch connected to Aruba controller

    Hi,

    If I'm not wrong NATing is configured at L3 Switch right ? if so, I believe controller will pass the traffic through the tunnel.

    Hi. 

     

    I believe you have IPSec tunnel (Site to Site). if so why do you want to NAT the traffic ? correct me if I understood it wrongly.
