Chapter 6: Configuring the Wireless-G Broadband Router
The Security Tab - Firewall

Wireless-G Broadband Router

The Security Tab - Firewall

Firewall Protection

. This feature employs Stateful Packet Inspection (SPI) for a more detailed review of data

packets entering your network environment.

Block WAN Requests

. Enable the Block WAN Request feature by checking the box beside

Block Anonymous

Internet Requests

and you can prevent your network from being “pinged,” or detected, by other Internet users.

The Block WAN Request feature also reinforces your network security by hiding your network ports. Both
functions of the Block WAN Request feature make it more difficult for outside users to work their way into your
network. This feature is enabled by default. Select

Disabled

to allow anonymous Internet requests.

Filter Multicast

. Multicasting allows for multiple transmissions to specific recipients at the same time. If

multicasting is permitted, then the Router will allow IP multicast packets to be forwarded to the appropriate
computers. Select

Enabled

to filter multicasting, or

Disabled

to disable this feature.

Filter Internet NAT Redirection

. This feature uses port forwarding to block access to local servers from local

networked computers. Select

Enabled

to filter Internet NAT redirection, or

Disabled

to disable this feature.

Filter IDENT (Port 113)

. This feature keeps port 113 from being scanned by devices outside of your local

network. Select

Enabled

to filter port 113, or

Disabled

to disable this feature.

Change these settings as described here and click the

Save Settings

button to apply your changes or

to cancel your changes.

The Security Tab - VPN Passthrough

Use the settings on this tab to allow VPN tunnels using IPSec, PPTP, or L2TP protocols to pass through the
Router’s firewall.

IPSec Pass-through

. Internet Protocol Security (IPSec) is a suite of protocols used to implement secure

exchange of packets at the IP layer. To allow IPSec tunnels to pass through the Router, click

Enable

.

IPSec Pass-

Through is enabled by default.

PPTP Pass-through

. Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Protocol (PPP) to be

tunneled through an IP network. To allow PPTP tunnels to pass through the Router, click

Enable

. PPTP Pass-

Through is enabled by default.

L2TP Pass-through

. Layer 2 Tunneling Protocol is the method used to enable Point-to-Point sessions via the

Internet on the Layer 2 level. To allow L2TP tunnels to pass through the Router, click

Enable

. L2TP Pass-Through

is enabled by default.
