Using a ZyXEL USG as a RADIUS server to authenticate users on a GS-Series Switch with 802.1X
There is a FAQ entry on using an external Radius server to allow users to be authenticated on a ZyXEL GS Series switch where 802.1X authentication has been enabled:
However, what if I were to want to use a ZyXEL USG to be the server for this purpose? 802.1X for wireless devices works just fine, but when I put the IP address of the USG into the Switch for RADIUS authentication, is doesn't work!
Can this be done? and if so, maybe there are some additional steps needed in the USG to authenticate the switch?
