Description

PPTP PassThrough

Enables the Point-to-Point Tunneling Protocol (PPTP) Pass-

Through protocol to be used through the SVG1501

Configuration Manager so that a VPN device (or software)

may communicate properly with the WAN.

Select

Enable

to turn on.

Remote Config Management

Allows remote access to the SVG1501 Configuration

Manager. This enables you to configure the SVG1501 WAN

by accessing the WAN IP address at Port 8080 of the

configuration manager from anywhere on the Internet. For

example, in the browser URL window, type

http://WanIPAddress:8080/

to access the SVG1501

Configuration Manager remotely.

Select

Enable

to turn on.

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 configuration manager.

Select

Enable

to turn on.

UPnP Enable

Turns on the Universal Plug and Play protocol (UPnP) agent

in the configuration manager. If you are running a CPE

(client) application that requires UPnP, select this box.

Select

Enable

to turn on.

Rg PassThrough

Disables NAT operation allowing all client computers to act

as passthrough clients.

Select

Enable

to turn on.

PassThrough Mac Addresses

Specifies up to 32 computers as passthrough clients not

subject to NAT, using their MAC addresses.

To enable this feature, your cable operator may need to

provide additional public IP addresses.

Advanced IP Filtering Page

Define which local PCs will be denied access to the SVG1501 WAN by configuring IP

address filters to block Internet traffic to specific network devices on the LAN. You enter

the LSB (Least-significant byte) of the IP address; the upper bytes of the IP address are

set automatically from the SVG1501 Configuration Manager’s IP address.

You can store filter settings commonly used but not have them active.

Field Descriptions for the Advanced IP Filtering Page

Field

Description

Start Address

Enter the starting IP address range of the computers you want to

deny access to the SVG1501 WAN.

Enter only the least significant byte of the IP address.

End Address

Enter the ending IP address range of the computers you want to

deny access to the SVG1501 WAN.

Enter only the least significant byte of the IP address.

Enabled

Activate the IP address filter.

Select each range of IP addresses you want to deny access to the

SVG1501 WAN.

Click

Apply

to activate and save your settings.

Advanced MAC Filtering Page

Define up to 20 Media Access Control (MAC) address filters to prevent PCs from

sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. The MAC

address of a specific NIC card never changes, unlike its IP address which can be

assigned via the DHCP server or hard-coded to various addresses over time.

Field Descriptions for the Advanced MAC Filtering Page

Field

Description

MAC Addresses

Media Access Control address — a unique set of 12 hexadecimal digits

assigned to a PC during manufacturing.

Setting a MAC Address Filter

1.

Enter the MAC address in the MAC Addresses field for the PC you want to block.

2.

Click

Add MAC Address

.

3.

Repeat above steps for up to twenty MAC addresses.

Advanced Port Filtering Page

Define port filters to prevent all devices from sending outgoing TCP/UDP traffic to the

WAN on specific IP port numbers. Specify a starting and ending port range to determine

what TCP/UDP traffic is allowed out to the WAN on a per-port basis.

Note:

The specified port ranges are blocked for ALL PCs. This setting is

not IP address or MAC address specific. For example, to block all PCs

on the private LAN from accessing HTTP sites, set the “Start Port” to

80

, “End Port” to

80

, “Protocol” to

TCP

, select

Enabled

, and then click

Apply.

Field Descriptions for the Advanced Port Filtering Page

Field

Description

Start Port

Enter the starting port number.

End Port

Enter the ending port number.

Protocol

Select

TCP

,

UDP

, or

Both

from the drop-down list.

Enabled

Select to activate the IP port filters.

Advanced Port Forwarding Page

Run a publicly accessible server on the LAN by specifying the mapping of TCP/UDP ports

to a local PC. This enables incoming requests on specific port numbers to reach web
