FIREWALL
GWN7000 supports firewall feature to control incoming and outgoing traffic by restricting or rejecting specific
traffic, as well as preventing attacks to the GWN7000 networks for enhanced security.
The Firewall feature includes 3 menus:
• Basic Settings: Used to enable SYN Flood, setup port forwarding, DMZ, inter-group traffic
forwarding and UPnP.
• Traffic Rules: Used to control incoming/outgoing traffic in customized scheduled times, and taking
actions for specified rules such as Accept; Reject and Drop.
• Advanced: Used to setup SNAT and DNAT.

Flush Connection Reload: When this option is enabled, and a firewall configuration change is made,
existing connections that had been permitted by the previous firewall rules will be terminated.
That way if the new firewall rules can’t permit a connection that had been previously established, it will be
terminated and won’t be able to reconnect.
When this option is disabled, existing connections are allowed to continue until they do timeout, even if the
new rules wouldn’t allow these connections to be established.
