Using SSL Connections
The VPN firewall provides a hardware-based SSL VPN solution designed specifically to provide
remote access for mobile users to their corporate resources, bypassing the need for a
preinstalled VPN client on their computers. Using the familiar Secure Sockets Layer (SSL)
protocol, commonly used for e-commerce transactions, the VPN firewall can authenticate itself
to an SSL-enabled client, such as a standard web browser. Once the authentication and
negotiation of encryption information are completed, the server and client can establish an
encrypted connection. With support for up to 5 dedicated SSL VPN tunnels, the VPN firewall
allows users to easily access the remote network for a customizable, secure, user portal
experience from virtually any available platform.

SSL VPN Portal Options
The VPN firewall’s SSL VPN portal can provide two levels of SSL service to the remote user:
• SSL VPN
tunnel. The VPN firewall can provide the full network connectivity of a VPN
tunnel using the remote user’s browser instead of a traditional IPSec VPN client. The
SSL capability of the user’s browser provides authentication and encryption, establishing
a secure connection to the VPN firewall. Upon successful connection, an ActiveX-based
SSL VPN client is downloaded to the remote computer to allow the remote user to
virtually join the corporate network.
