The settings for manually unblocking certain
communication ports in your private network.
Reserved Ports
is a list of logical ports that cannot be used to access
your private network from the public Internet.
Port Forwarding to LAN
lets you specify which ports clients on the
public Internet shall be able to communicate through, to clients on
your private network. Under
Port Range
, select a range (any range that
does not contain the ports listed under
Reserved Ports
) from 0-65535.
Select the type of traffi c that should be let through on these ports,
TCP
or
UDP
, or
Both
. Finally, type in the
Destination Address
, which
is the IP address of the client on your private network that you want
to be accessible from the public Internet. Click on
Add
when you are
fi nished. Note that by default, no traffi c is permitted inwards if the
request is initiated by an external user. However, clients on your private
network can always access the public Internet.
Click on

LAN->UPnP:
The settings for Universal Plug and Play.
The 4GR supports Universal Plug and Play. UPnP is a feature that
enables client application on devices behind the 4GR to automatically
trigger the opening of TCP/UDP ports through the fi rewall in the
4GR.
As a security precaution, this feature is disabled by default and can be
enabled manually.
