I am trying to do mac authentication with Vircom Radius and have the AP send over the client’s wireless mac as the username and no password. The problem that I run into is when the CPE boots it starts the accounting request and completes that but it never sends an access request. If i make changes to the access list which i am not using for this but I know that it looks to the access list first then radius after i apply changes(disable a blank rule that i create) then it will send the access request but i still cannot get online or get an IP address. VOPtest which is Vircom’s test software for Radius says that everything is good if i could just get the AP or CPE to send the access request to Radius. Any help is appreciated, Thanks. 
I have never used Vircom, but have a system running with Mikrotik and FreeRadius, so Mikrotik+Radius certainly can work.
Please explain how you are authenticating the CPE.
Are you authenticating it when it associates with the AP, thru PPPoE etc, or is it HotSpot ?
One common pitfall is that you have not allowed the IP range of the network containing the access points to access the Radius server (clients.conf in Free Radius).
I forgot to mention :-
Different Radius setups require the MAC to be passed as XX-YY-ZZ rather.. than XX:YY:ZZ..
Hopefully you have a debug output, log, or maybe an ‘interactive’ server option so you can see wtf happens when you try to authenticate.
I have it working fine utilizing hotspot mac auth but the problem is people will get one address from the hotspot controller and then a different address from the dhcp server and then all the sudden the user gets the hotspot login page and we have to kick them from the hotspot hosts tab and then they get right on. I would love to drop hotspot and somehow do the mac auth based on the cpe mac address. Basically I would like a setup just like mikrotik does pppoe server with the profiles but for mac auth.
Why not just make a Wireless security profile that authenticates the connectng MAC using Radius ?
The whole idea of hotspot is to redirect connecting users to a Pay Now page.
OH !
I fogot to mention - have a look at your Idle Timeouts under both server and client profiles.
Did you ever get this resolved? I use Vircom as well for RADIUS for dialup (yes dial up still exists in a our little town.) I have more wireless customers that I need to control better and I would love to implement Vircom with our wireless and then redirect to a pay now page if possible.
If you got it to work please explain your setup better to help the rest of us Vircom people out here.

How do your wireless customers connect? If you’re doing Hotspots you can obviously do payment pages. You can also do payment reminders for PPP clients.
I mean did you ever get Vircom Radius to work as the auth for your hotspot users or PPPOE or PPPOA customers. All hotspots do not require a Radius manager they can also be setup local to the hotspot. But we are using the RadiusManager3 at all sites this is handy. We have hard set usernames and passwords for techs and special guests on our Hotspots but we primarily use RadiusManager3. It is awesome!
But to get to my question. If jbowsher (or any other Vircom radius user ) would please reply with what he did to get it working that would really help me out. Thanks in advance.!
