The
Firewall Configuration
window allows the
Router to enforce specific predefined policies
intended to protect against certain common types
of attacks. There are two general types of
protection (DoS, Port Scan) that can be enabled on
the Router, as well as filtering for specific packet
types sometimes used by hackers.
You can choose to
enable or disable protection
against a customized basket of attack and scan
types. To use
DoS Protection
or
Port Scan
Protection
, select the
State
Enabled radio button
for the protection type and click in the selection
boxes for the various types of protection listed
under each.
Note
Service Filtering may
interfere with other
configurations such as
DHCP Relay or Remote
Management via Telnet.
