Configuring LAN WAN Rules
The default outbound policy is to allow all traffic to the Internet to pass through. Firewall rules can
then be applied to block specific types of traffic from going out from the LAN to the Internet
(outbound). The default policy of Allow Always can be changed to block all outbound traffic
which then allows you to enable only specific services to pass through the VPN firewall.
To change the default outbound policy:
1. Select Security from the main menu and Firewall Rules from the submenu. The LAN WAN
Rules screen displays (see Figure 4-1 on page 4-8).
2. Change the Default Outbound Policy by selecting Block Always from the pull-down menu.
3. Click Apply.
