Manage NAT Filtering
Network Address Translation (NAT) determines how the modem 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 WiFi-enabled computer or mobile device that is connected to the network.
2. Enter http://www.routerlogin.net.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin.The default password is password.The user name and password are
case-sensitive.

when the SIP ALG is enabled. For this reason, the modem router provides the option to disable the SIP
ALG.
To change the default SIP ALG setting:
1. Launch a web browser from a WiFi-enabled computer or mobile device that is connected to the network.
2. Enter http://www.routerlogin.net.
A login window opens.
