Client over the ZyWALL USG
In the following example, we will employ Two-factor Authentication (ZyXEL OTP pack) to enhance
password security by using SSL VPN application provided by ZyWALL USG.
In order to use this application, you are required to configure your ZyWALL USG and SafeWord according
to the following steps:
2.
Install the SafeWord server software on a computer.
(Note: Please refer to the SafeWord installation guide in Chapter 2. For more details, please check the
SafeNet website for the installation documentation)
2. Create the user accounts on the ZyWALL USG and in the SafeWord server.
3. Import each token’s database file into the server.
4. Assign the users to the OTP tokens (on the SafeWord server).
5. Configure the SafeWord as a RADIUS server in the ZyWALL USG Object > AAA Server screens.
6. Distribute the OTP tokens to (local or remote) the users who will remote login into the ZyWALL USG.
Note: ZyWALL OTP is a stand-alone product, which is not included in the ZyWALL USG package.
Network Topology
In this example, we will have one token and we will create user “OTP” who will be the authenticator to
establish the IPSec VPN tunnel to ZyWALL USG.
