Configuring the SSL VPN Client

The SSL VPN Client within the VPN firewall will assign IP addresses to remote VPN tunnel
clients. Because the VPN tunnel connection is a point-to-point connection, you can assign IP
addresses from the corporate subnet to the remote VPN tunnel clients.
Some additional considerations are:
• So that the virtual (PPP) interface address of a VPN tunnel client does not conflict with
addresses on the corporate network, configure an IP address range that does not directly
overlap with addresses on your local network. For example, if 192.168.1.1 through
192.168.1.100 are currently assigned to devices on your local network, then start the client
address range at 192.168.1.101 or choose an entirely different subnet altogether.
• The VPN tunnel client cannot contact a server on the corporate network if the VPN tunnel
client's Ethernet interface shares the same IP address as the server or the VPN firewall (for
example, if your laptop has a network interface IP address of 10.0.0.45, then you will not be
able to contact a server on the remote network that also has the IP address 10.0.0.45).
• If you assign an entirely different subnet to the VPN tunnel clients than the subnet used by the
corporate network, you must
– Add a client route to configure the VPN tunnel client to connect to the corporate network
using the VPN tunnel.
– Create a static route on the corporate network's firewall to forward local traffic intended
for the VPN tunnel clients to the VPN firewall.
• Select whether you want to enable full tunnel or split tunnel support based on your bandwidth:
– Full tunnel. Sends all of the client's traffic across the VPN tunnel.
– Split tunnel. Sends only traffic destined for the corporate network based on the specified
client routes. All other traffic is sent to the Internet. Split tunnel allows you to manage
your company bandwidth by reserving the VPN tunnel for corporate traffic only.
