Default Security Policy

The ZoneAlarm default security policy includes the following rules:

• Access is blocked from the WAN (Internet) to the internal networks (LAN and WLAN).
• Access is allowed from the internal networks to the WAN, according to the firewall security level (Low/Medium/High).
• Access is allowed from the LAN network to the WLAN.
• If you chose "Firewall Mode" during setup, either in the ZoneAlarm Setup Wizard or in the Wireless Configuration Wizard:
  • Access is blocked from the WLAN to the LAN.
  • HTTP access to the ZoneAlarm Portal (my.firewall and my.vpn) is allowed from the LAN, but not from the WLAN. You can allow HTTP access from the WLAN, by creating a specific user-defined firewall rule.
• When using the print server function (see Using Network Printers), access from internal networks to connected network printers is allowed.
• Access from the WAN to network printers is blocked.

These rules are independent of the firewall security level.

You can easily override the default security policy, by creating user-defined firewall rules. For further information, see Using Rules.
