NAT Filtering : This option determines how the router deals with inbound traffic. The Secured option provides a secured firewall to protect the PCs on LAN from attacks from the Internet, but it may cause some Internet games, point-to-point applications, or multimedia applications not to work. The Open option, on the other hand, provides a much less secured firewall, while it allows almost all Internet applications to work.
- Login to router
- Find WAN settings, located on left hand side of the menu. Here you will set NAT filtering to "open". Then save the changes!
- It may ask you to reboot the router.
