SSL VPN is a flexible and secure way to extend network resources to virtually any
remote user. The security appliance supports the SSL VPN, and interoperates with
the Cisco AnyConnect VPN Client software.
Figure 12 shows an example of SSL VPN. Users can remotely access the network
by using the Cisco AnyConnect VPN Client software. When the VPN tunnel is
established, each user will have an IP address on the internal network, such as
10.10.10.x.
