Configuring Firewall Settings
The Altitude 35xx's firewall is a set of related programs located in the gateway on the WAN side of the
Altitude 35xx. The firewall uses a collection of filters to screen information packets for known types of
system attacks. Some of the Altitude 35xx's filters are continuously enabled, others are configurable.
Use the Altitude 35xx’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 Altitude 35xx firewall settings:
1 Select Network Configuration > Firewall from the Altitude 35xx menu tree.
2 Refer to the Global Firewall Disable field to enable or disable the Altitude 35xx firewall.
3 Refer to the Timeout Configuration field to define a timeout interval to terminate IP address
translations.
Disable Firewall Select the Disable Firewall checkbox to disable all firewall
functions on the Altitude 35xx. This includes firewall filters,
NAT, VP, content filtering, and subnet access. Disabling
the Altitude 35xx firewall makes the Altitude 35xx
vulnerable to data attacks and is not recommended during
normal operation if using the WAN port.
