7. Virtual Private Networking
Using SSL Connections
The wireless 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 wireless 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
wireless 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 wireless VPN firewall’s SSL VPN portal can provide two levels of SSL service to the
remote user:
• SSL VPN tunnel. Th
e wireless 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 wireless 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.
