Firewall - D-Link DSL-G604T User Manual

Firewall

The Firewall Configuration menu 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 enable DoS Protection or Port Scan
Protection, select the Enable radio button for the
protection type and click in the selection boxes
for the various types of protection listed under
each.
Service Filtering may
interfere with other
configurations such as
Note DHCP Relay or Remote
Management via Telnet.
When DoS, Port Scan, or Service Filtering Protection is enabled, it will create a firewall policy to protect your
network against the following:
