Configuring the Firewall
The 6400-S can act as a firewall. A firewall restricts and controls the traffic
between networks, typically between a corporate network and the Internet. If
an external firewall is used, the firewall features can be set to pass or block
traffic depending on whether the 6400-S is placed in series or in parallel with
the external firewall.
To configure the firewall, you can:
• Configure basic settings.
• Configure advanced settings
• Enable or disable the firewall.
Configuring the firewall basic settings
The basic settings are under Basic LAN (Subscriber) and WAN (Provider)
Firewall Settings on the Firewall configuration page.
