6.10 Configuring Firewall Settings
The AP-5131's firewall is a set of related programs located in the gateway on the WAN side of the
AP-5131. The firewall uses a collection of filters to screen information packets for known types of
system attacks. Some of the AP-5131's filters are continuously enabled, others are configurable.
Use the AP-5131’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 AP-5131 firewall settings:
1. Select Network Configuration -> Firewall from the AP-5131 menu tree.
Pre-Authentication Selecting this option enables an associated MU to carry out an
802.1x authentication with another AP-5131 before it roams to it.
The AP-5131 caches the keying information of the client until it
roams to the other AP-5131. 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.
