The ability to define network access rules is a very
powerful management tool. Using a custom rule, it's
possible to disable all firewall protection, creating
holes in the firewall, or block all access to the
Internet. Use with extreme caution when creating or
deleting network access rules.
Network access rules will not disable protection fro
m
Denial of Service (DoS) attacks, such as SYN Flood, Ping
of Death, Port Scan, etc. However, it's possible to
create vulnerabilities to attacks that exploit
vulnerabilities in applications.
WAN to LAN Access Rules
This pages allows you to define WAN-to-LAN network access rules which evaluate the network traffic's
source IP address, destination IP address, and communication port to decide if it's allowed to pass
through the firewall.
By default, the stateful packet inspection module of this router blocks all traffic to the LAN that
originates from the Internet. The behavior is defined by the default stateful packet inspection enabled in
the router:
Forward all sessions originating from the LAN to the Internet (Pleaes refer to the “LAN-to-WAN
Access Rules” at System Setup Firewall LAN-to-WAN Access Rules).
Discard all sessions originating from the Internet to the LAN.
Additional access rules may be defined to extend or overwrite the default rules.

Dynamic DNS Setting
This section allows you to set up advanced features in this router. During the design stage, we have
given much thought to making this router as convenient and easy to use as possible. However, some
more advanced knowledge about TCP/IP might still be required.
Dynamic DNS: Each time the WAN address is changed, DDNS service will automatically update it to
dyndns.org. You can register your account at :http://www.dyndns.org
