Setting Up a Bridge Network

The Bridge Network pane allows you to create a local network that has broadband-accessible IP addresses.

Bridge Network is a public network in which the local network is an extension of the broadband network and

does not require any special routing. Computers that are assigned Bridge Network IP addresses operate

without Network Address Translation (NAT). This feature is typically used in conjunction with broadband

service that provides a range of IP addresses. Once enabled, the bridge network IP addresses can be

assigned to local computers.

To set up a bridge network:

1.

Check the

Enable

checkbox.

2.

In the Subnet Mask field, enter the subnet mask (this is typically provided by your service provider, and

defines how large your IP pool is).

3.

Firewall Tab

This chapter describes the 2Wire gateway firewall features, and provides detailed instructions on how to

modify the firewall settings.

Firewall Features

The 2Wire gateway has a professional-grade firewall to help prevent unauthorized users from accessing

your local network. The 2Wire gateway firewall includes the following features:

Stateful packet inspection.

Blocks common Denial of Service attacks (such as SYN/FIN flooding or Smurf),

and detects and logs TCP and UDP port scans.

Stateless packet inspection.

Filters specific NetBios traffic, suspicious packets and IP fragments; blocks

packets sent from the private network to the Internet that have spoofed IP addresses.

Network Address Translation (NAT).

Translates a local network’s IP address to an external address

maintained by the 2Wire gateway, effectively “hiding” the existence of a home network to the Internet. The

2Wire gateway then uses this external address to communicate with the Internet on behalf of devices

connected to the local network.

Port Address Translation (PAT).

A function provided by some routers which allows hosts on a LAN to

communicate with the rest of a network (such as the Internet) without revealing their own private IP

address. All outbound packets have their IP address translated to the router’s external IP address. Replies

come back to the router, which then translates them back into the private IP address of the original host for

final delivery. During PAT, each computer on the LAN is translated to the same IP address, but with a

different port number assignment.

Inbound and outbound port blocking.

Blocks common inbound and outbound protocol types from passing

information to or receiving information from the Internet.
