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
