I have a customer that’s looking to setup DUO for their SonicWALL SSLVPN appliance. The firmware is 8.6+ so we can’t use the web console we have setup RADIUS auth and it’s working fine.
My issue is since we are using MSCHAPv2 the users can’t append their 2FA choice at login since the DUO proxy can’t see the password string so it defaults to the DUO app.
Most of the clients are using the DUO Moble App but a select few sometimes have the need to connect to the VPN but they won’t have their devices handy so they want the ability to add a landline to their account and use that to connect to the VPN.
My issue/question when I try and test this even when I use the self-service portal to change the default device to the landline and then connect to the VPN it always sends a push and never a call. If I remove the mobile device from the users profile it makes a call without issue. Is there a way to make the call work while keeping the mobile device setup on the users profile?
