Enable Concurrent NAT/NAPT

Note

You can define concurrent NAT/NAPT on only one WAN interface.

Typically, NAT may be used to make a single LAN-side host visible on the WAN, and NAPT makes

multiple hosts visible. Your service provide may also offer concurrent NAT/NAPT wherein a single

WAN interface may support multiple NAT connections, each of which makes a single LAN-side host

visible on the WAN. Through either NAT or NAPT, the router ensures that the LAN-side host is known

to the WAN only through the public IP address of the router’s WAN-side connection.

The host’s actual

private IP address remains unknown to any WAN-side hosts or servers.

The

Current Public/Private IP Address Map

table allows you to define the mapping of public IP

addresses, supplied by your service provider, to the private IP addresses used on your local LAN.

Note

If you enable concurrent NAT/NAPT, you

must

define at least one entry in the

Current

Public/Private IP Address Map

table.

1.

In the WAN interface row under

NAT

Port Forwarding

Port forwarding allows selected servers running on the LAN side of the router to be accessed from the

WAN side. Requests from the WAN to a configured TCP or UDP port will forwarded to the selected IP

address on the LAN.

In order to provide such access, your SpeedStream router may be configured to forward certain inbound

traffic from the WAN-side to a specified LAN-side server. WAN-side connections have knowledge of,

and hence direct access to, only the known

public

IP address associated with the WAN-side interface of

your SpeedStream device.

This methodology is commonly referred to as

port forwarding

, and is implemented by means of a

Network Address Port Translation

(NAPT) operation.

Port Forwarding Configuration Options

Select service by name:

You can select either a service name or protocol to which the port forwarding rule will be applied.

•

Select protocol:

To apply the port forwarding rule to a protocol, select

TCP

,

UDP

,

ICMP

or

GRE

from the

Protocol

list.

Enter port range for TCP/UDP protocol:

Required if you selected the TCP or UDP protocol, you must also define

either a single port or range

of ports.

Redirect selected protocol/service to this router/IP address:

Select this option if the server for the previously specified service or protocol resides on the router.

Redirect selected protocol/service to IP address:

Select this option if the server for the previously specified service or protocol resides on a host

located on the LAN. In this case, you must specify the IP address of the host on which the server

resides. (This option is usually selected.)

Manage Network Address Port Mappings through UPnP

If you have enabled UPnP on the SpeedStream router, you can use UPnP to manipulate the NAPT port

mappings. This is effectively the same as if you had logged into the router’s Web management interface

through your Internet browser.

For more information on port mappings, refer to page 65,

NAT/NAPT

. For more information about UPnP,

refer to page 16, Logging In with UPnP or page 82,

UPnP (Universal Plug and Play).

Firewall

Your SpeedStream router includes a user-configurable firewall that provides various levels of security

against outside attacks. This firewall provides only WAN-side protection. The firewall does not provide

any LAN-side protection.

The firewall also includes an advanced

Attack Detection System (ADS)

containing various algorithms to

detect and identify WAN attacks the moment they start and protect the LAN from such attacks. Though

WAN access may be temporarily hindered, the LAN is protected from such harmful traffic load.
