incoming packet is in response to an outgoing request, but true stateful packet inspection 
goes far beyond NAT.

For IPv6, which in itself provides stronger security than IPv4, a firewall in particular controls 
the exchange of traffic between the Internet, DMZ, and LAN.

Administrator Tips

Consider the following operational items:

As an option, you can enable remote management if you have to manage distant sites 
from a central location (see 

page 296 and 

on page 331).

Although rules are the basic way of managing the traffic through your system (see 

on page 129), you can further refine your 

control using the following features and capabilities of the wireless VPN firewall:

Groups and hosts (see 

Services (see 

on page 133)

Schedules (see 

Allowing or blocking sites (see 

Source MAC filtering (see 

on page 183)

Port triggering (see 

on page 190)

Some firewall settings might affect the performance of the wireless VPN firewall. For more 
information, see 

on page 322.

The firewall logs can be configured to log and then email denial of access, general attack, 
and other information to a specified email address. For information about how to configure 
logging and notifications, see 

Overview of Rules to Block or Allow Specific Kinds of 
Traffic

Firewall rules are used to block or allow specific traffic passing through from one side to the 
other. You can configure up to 800 firewall rules on the wireless VPN firewall (see the 
following table). Inbound rules (WAN to LAN) restrict access by outsiders to private 
resources, selectively allowing only specific outside users to access specific resources. 
Outbound rules (LAN to WAN) determine what outside resources local users can have 
access to.
