6.10 Configuring Firewall Settings
The access point's firewall is a set of related programs located in the gateway on the WAN side of
the access point. The firewall uses a collection of filters to screen information packets for known
types of system attacks. Some of the access point's filters are continuously enabled, others are
configurable.
Use the access point’s Firewall screen to enable or disable the configurable firewall filters. Enable
each filter for maximum security. Disable a filter if the corresponding attack does not seem a threat
in order to reduce processor overhead. Use the WLAN Security screens (WEP, Kerberos etc.) as
required for setting user authentication and data encryption parameters.
To configure the access point firewall settings:
1. Select Network Configuration -> Firewall
from the access point menu tree.
Pre-Authentication Selecting this option enables an associated MU to carry out an
802.1x authentication with another
access point before it roams
to it. The
access point caches the keying information of the client
until it roams to the other
access point. This enables the roaming
client to start sending and receiving data sooner by not having to
do 802.1x authentication after it roams. This feature is only
supported when 802.1x EAP authentication is enabled.
