Disable port scan and DoS protection:
Denial of service (DoS) protec-
tion protects your LAN against DOS attacks. Generally, please enable the
port scanning and DOS protection function.
Respond to Ping on Internet Port:
If enabled, the router responds to
ping commands from the Internet. However, like the DMZ server, enab-
ling this function can bring about security risks. Generally, please disable
this function.
NAT Filtering:
NAT filtering determines the way that the router deals
with incoming traffic.
Secured: This option provides a secured firewall to protect PCs on LAN
from attacks from the Internet, but it may not allow some Internet
games, point-to-point applications, or multimedia applications to
work.
Open: This option provides a less secure firewall that allows almost all
Internet applications to work. After finishing the settings, click Apply
to apply the settings.
