Have anyone encountered this problem before? My radius is at 192.168.1.10 and R1 is on 192.168.1.1. Both are connected to a switch and ping works perfect. ACS has been configured with R1 as the AAA client with a key. I'm baffled as to why this does not work. I've even changed the authentication to TACACS+ and still the same problem occurs.
