Manage Nat Filtering; Enable And Configure A Vlan - NETGEAR D6100 User Manual

AC1200 WiFi DSL Modem Router—Essentials Edition Model D6100

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 an Internet browser from a computer or WiFi device that is connected to the
network.
2. Type http://www.routerlogin.net.
A login screen displays.
3. Enter the user name and password for the modem router.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
4. Click the OK button.
The BASIC Home screen displays.
5. Select ADVANCED > Setup > WAN Setup.
The WAN Setup screen displays.
6. Select a NAT Filtering radio button:
• Secured. Provides a secured firewall to protect the computers on the LAN from
attacks from the Internet but might prevent some Internet games, point-to-point
applications, or multimedia applications from functioning. By default, the Secured
radio button is selected.
• Open. Provides a much less secured firewall but allows almost all Internet
applications to function.
7. Click the Apply button.
Your settings are saved.

Enable and Configure a VLAN

A network of computers and devices can behave as if they are connected to the same
network even though they might actually be physically on different segments of a LAN. Virtual
LANs (VLANs) are configured through software rather than hardware, which makes them
very flexible.
If you enable a VLAN and if the network devices (hubs and switches) on your LAN support
the VLAN (802.1Q) standard, the VLAN ID for the wireless access point is associated with all
traffic coming from the modem router.
