Description

WAN Blocking

Prevents the Cable Modem/Router or the PCs from responding to

pings to the Cable Modem/Router’s WAN IP address or to the

devices behind it. This makes it more difficult for hackers to attack

your PCs and other devices on your network.

IPSec/PPTP

PassThrough

Enable to support VPN devices or software on your network.

Remote

Configuration

Management

Allows the Cable Modem/Router to be remotely administered at

port 8080. When enabled, navigate to http://CMIPAddress:8080/ to

administer the Cable Modem/Router remotely). You can find your

CM: WAN IP address on the

Basic Setup

page.

Multicast

Enable

Allows multicast specific traffic (denoted by a multicast specific

address) to be passed to and from the PCs on the private network

behind the Cable Modem/Router.

UPnP Enable

Select Enable to enable the UPnP agent in the Cable

Modem/Router. If you are running an application that requires

UPnP, check this box.

Primary

Network

Bridged

Allows all LAN hosts to bypass NAT and the Cable Modem/Router's

LAN DHCP Server. Adding MAC addresses into the table is not

required. If MAC addresses are added to the table then only those

MAC addresses in the list will bypass NAT and the LAN DHCP. All

other LAN hosts NOT in the list will use the

NAT and LAN DHCP

Server as normal.

NAT ALG

Status

The NAT ALG section shows which ALGs (Application Layer

Gateway) are allowed to pass through the NAT Firewall.

Most

users will not need to change these settings.

IP Filtering

The IP Filtering page allows you to configure IP address filters in order to block specific

network devices on your LAN from accessing the Internet. By entering starting and

ending IP address ranges, you can configure which local PCs are denied access to the

WAN.

We recommend assigning a static IP address to your computer when using IP Filtering.

By default, the Cable Modem/Router uses DHCP to assign IP addresses. DHCP does

not guarantee that your computer will be assigned the same IP address. When assigning

a static IP address to your computer you should select an address that is outside the IP

addresses assigned by the Cable Modem/Router’s DHCP server.

By default the DHCP

Server assigns addresses from 192.168.0.10 to 192.168.0.255.

We recommend using

192.168.0.6 as the static IP address for your computer.
