CS-ACS and NAT

Hello,

Currently, we have FWSM/7606 sitting between a CS-ACS appliance v4.0.1 and the network comprising several routers. Since we use NAT, all network devices appear as a single IP address in CS-ACS.

Is there a way to convey the real router IP address into CS-ACS, either in the T+ payload or by other means ?

We need to see, in CS-ACS logs, both the Real IP and the NAT IP (we already have this one).

Thanks in advance.

I've looked at a tacacs+ auth request in ethereal and I'm pretty sure the source adress is lost. Also, if you review the rfc(http://www.cisco.com/warp/public/459/tac-rfc.1.76.txt) You will find that the is no source field.

Hi Dominic,

Thanks for your reply. Obviously, CS-ACS is an enterprise solution. We are in the outsourcing business / multi-client datacenter and we have to look at other avenues.

Regards.
