Securing Your Computer with the Mobile VPN Firewall
3
Define friendly networks and create firewall rules as described in the subsequent sections.
Defining friendly networks
Use the
Friendly Networks
tab to define specific known networks for which you want to generate a
firewall rule set. For example, if you want to use the Mobile VPN client on a local network where you do
not want your computer firewalled from other computers, you can add the network address of that
LAN as a friendly network to differentiate the firewall rules for that LAN from the firewall rules you cre-
ate for connections to the Internet and to remote VPN networks.
1
On the
Firewall Settings
dialog box, click the
Friendly Networks
tab.
2
Click
New
to add a new friendly network.
The Automatic Friendly Network detection feature does not work in this release of the Mobile VPN with
IPSec client software.
Creating firewall rules
Use the
Firewall Rules
tab to create exceptions to the firewall mode you set when you enabled the fire-
wall. For example, if you selected
Basic Locked Settings
, then the rules you create here allow traffic. If
you selected
Basic Open Settings
, then the rules you create here deny traffic. Firewall rules can
include multiple port numbers from a single protocol.
The check boxes below
View Settings
allow you to show or hide categories of firewall rules.
