Chapter 13 Firewall Configuration

149

This chapter shows you how to enable and configure the Prestige firewall.

The web configurator is, by far, the most comprehensive firewall configuration tool your 
Prestige has to offer. For this reason, it is recommended that you configure your firewall using 
the web configurator. SMT screens allow you to activate the firewall. CLI commands provide 
limited configuration options and are only recommended for advanced users.

Firewall rules are grouped based on the direction of travel of packets to which they apply:

By default, the Prestige’s stateful packet inspection allows packets traveling in the following 
directions:

• LAN to LAN/ Router 

This allows computers on the LAN to manage the Prestige and communicate between 
networks or subnets connected to the LAN interface.

• LAN to WAN

By default, the Prestige’s stateful packet inspection blocks packets traveling in the following 
directions:

• WAN  to  LAN
• WAN  to  WAN/  Router 

This prevents computers on the WAN from using the Prestige as a gateway to 
communicate with other computers on the WAN and/or managing the Prestige.

You may define additional rules and sets or modify existing ones but please exercise 
extreme caution in doing so.
