ProSafe VPN Firewall 200 FVX538 Reference Manual
4-8 Firewall Protection and Content Filtering
v1.0, March 2009
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.
Bandwidth Profile Bandwidth Limiting determines the way in which the data is sent to/from your host.
The purpose of bandwidth limiting is to provide a solution for limiting the outgoing/
incoming traffic, thus preventing the LAN users for consuming all the bandwidth of
our internet link. Bandwidth Limiting for outbound traffic will be done on the available
WAN interface in the single port and Auto-Failover modes. The limiting will be done
on the user-specified interface in Load Balancing mode. The bandwidth limiting for
inbound traffic will be done on the LAN interface for all WAN modes. Bandwidth
Limiting will not apply to the DMZ interface.
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.
