Hi everyone, I´m trying to setup a network with 802.1x, everything fine with one AP, put the AP ip address in the NPS configuration and it worked flawlessly. Now I need to plan a deployment with 12 APs, which IP address shall I use? the user guide says: "NAS IP address—Enter an arbitrary IP address to be used as RADIUS attribute 4, NAS IP Address, without changing source IP Address in the IP header of the RADIUS packet." What is "arbitrary" in this case? any of the APs IP adresses? what it that AP is down? Should I use an address not used in the same segment? the latter is like the IP address we set to Instant´s VC Thanks for your comments
