Firewall - D-Link DSL-G684T User Manual

Firewall

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.
Service Filtering may
interfere with other
configurations such as
DHCP Relay or
Note
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:
