ProSafe VPN Firewall 200 FVX538 Reference Manual
4-6 Firewall Protection and Content Filtering
v1.0, August 2006
Remember that allowing inbound services opens holes in your VPN firewall. Only enable those
ports that are necessary for your network. It is also advisable to turn on the server application
security and invoke the user password or privilege levels, if provided.
QoS Priority This setting determines the priority of a service, which in turn, determines the quality
of that service for the traffic passing through the firewall. By default, the priority
shown is that of the selected service. The user can change it accordingly. If the user
does not make a selection (i.e., leaves it as None), then the native priority of the
service will be applied to the policy. See “Setting Quality of Service (QoS) Priorities”
on page 4-23.
Log This determines whether packets covered by this rule are logged. Select the desired
action:
• Always – Always log traffic considered by this rule, whether it matches or not. This
is useful when debugging your rules.
• Never – Never log traffic considered by this rule, whether it matches or not.
Note: Some residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to the Acceptable Use
Policy of your ISP.
