Manage NAT Filtering
Network Address Translation (NAT) determines how the router processes inbound traffic. Secured NAT protects
computers on the LAN from attacks from the Internet but might prevent some Internet games, point-to-point
applications, or multimedia applications from working. Open NAT provides a much less secured firewall but allows
almost all Internet applications to work. Secured NAT is the default setting.
To change the default NAT filtering settings:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter http://www.routerlogin.net.
A login window opens.
3.
Enter the router user name and password.
The user name is admin. The default password is password. The user name and password are case-sensitive.
The BASIC Home page displays.

Manage the SIP Application-Level Gateway
The application-level gateway (ALG) for the Session Initiation Protocol (SIP) is enabled by default for enhanced
address and port translation. However, some types of VoIP and video traffic might not work well when the SIP ALG
is enabled. For this reason, the router provides the option to disable the SIP ALG.
