Manage the Network Address Translation
Network Address Translation (NAT) determines how the cable data gateway processes
inbound traffic. NAT provides one-to-many translation of IP addresses between devices. This
means that your network presents only one IP address to the Internet, and outside users
cannot directly address any of your local devices on your LAN. Leave NAT enabled to allow
multiple devices on your network to access the Internet using a single public IP address. NAT
is enabled by default.
Situations might occur in which you want to disable NAT.
To manage NAT:
1. On your computer
, launch an Internet browser such as Mozilla Firefox or Microsoft
Internet Explorer.
2. In the address field of your browser
, enter http://routerlogin.net.
You are prompted to enter a user name and password.
3. T
ype admin for the user name and type your password.
If you did not yet personalize your password, type password for the password.
4. Click the OK button.
The BASIC Home screen displays.
5. Select ADV
ANCED > Advanced Setup > NAT Mode.
The NAT screen displays.
By default, the Turn NAT On check box is selected.
6. T
o disable NAT, clear the Turn NAT On check box.
