CONFIGURATION
15.1
Firewall Configuration
The following screen will be displayed if you select
Configuration > Firewall
from the menu options. If you
change any settings in this screen, you must click
Save
to save the settings.
The firewall enforces rules about what network traffic is allowed to enter or leave your computer or network. The
firewall comes with some preconfigured rules and you can add more rules, if desired. After the rules are in place, the
firewall examines all network traffic and drops the traffic if the rules prohibit it.
Security Level
High
High security level only allows basic Internet functionality. Only Mail, News,
Web, FTP, and IPSEC are allowed. All other traffic is prohibited.
Medium
Like High security, Medium security only allows basic Internet functionality
by default. However, Medium security allows customization through NAT
configuration so that you can enable the traffic that you want to pass.
Low
Factory Default = Low
The Low security setting will allow all traffic except for known attacks. If
security is set to Low, the Gateway will be visible to other computers on the
Internet.
Off
Firewall is disabled. (All traffic is passed)
Firewall Logging
Log all permitted inbound traffic Factory Default = Disabled
