Two Factor Authentication via HMAIL and SMS software

Hi Experts

I want to configure my SSL VPN such a way that after user logs in using AD username and password then it should send the PIN code to the employee GSM sim and using that PIN cod it should complete the authentication.

Can any body provide the details on this setup and which software and how the integration will work?

Re: Two Factor Authentication via HMAIL and SMS software

Hi Aeroplane,

You can protect a SSL VPN with the Two Factor Authentication system SMS PASSCODE (

You set up your Juniper with Radius Authentication, and in Custum Radius challenge rule, you set incoming packet type as Access chanllenge.

The radius server must be a windows radius server (IAS or NPS). On this server you install the SMS PASSCODE protection.

You can send the one time pincode (OTP) as SMS to the employee GSM, either via a modem or via a via Telesign as SMS or as a call back (e.g. for PSTN lines).

You can have failover to e-mail e.g. if you have secure mail like Blackberry.

The OTP is first generated when username and password is validated, and tied to the specific session, and is also timebased.

I hope you can use this answer.

Best regards
