Need some advice. We have a Cisco 3650 switch which is acting as wireless controller with the IP address 192.168.0.2. I push AAA traffic to authenticate to a radius server 10.0.0.20 on port 1812 on another network segment. I can see the radius traffic hitting the radius server 10.0.0.20 but the IP hitting it is the routed port address 1.1.1.1 of the Cisco 3650 rather than the IP address of the switch 192.168.0.2.

I think this is because I haven't setup NAT, How would I configure NAT to use the Cisco 3650 IP address 192.168.0.2.

A cisco switch can not run nat.

It is somewhat unclear where the AAA traffic is originating since you mention a ASA.

If the traffic is being originated from the switch you can configure which interface the switch uses as the source ip. I forget the details but it is part of the radius config on the switch.

Apologies I meant to say how would I configure NAT on the Cisco ASA to present the Cisco 3650 ip address to the Radius server rather than the routed port IP address.

If you could point me to an example I would be most grateful.
