VPN Connectivity
Set up VPN tunnels with other companies, branch offices, telecommuters, and business travelers to
provide secure access to your network. You can also purchase the ZyWALL/USG OTPv2 One-Time
Password System for strong two-factor authentication for Web Configurator, Web access, SSL VPN,
and Zyxel IPSec VPN client user logins.

SSL VPN Network Access
SSL VPN lets remote users use their web browsers for a very easy-to-use VPN solution. A user just
browses to the ZyWALL/USG’s web address and enters his user name and password to securely
connect to the ZyWALL/USG’s network. Here full tunnel mode creates a virtual connection for a
remote user and gives him a private IP address in the same subnet as the local network so he can
access network resources in the same way as if he were part of the internal network.
