34 IG-4160 Zoom Internet Gateway User Guide
If you want to use a special service that isn’t on the Gateway’s
preprogrammed list, you can do so manually. Before you do so,
however, we recommend that you visit this web site:
http://www.practicallynetworked.com/sharing/specialapps.
htm. This site contains easy-to-understand instructions about
special services. It also includes a list of open ports, which you will
need to set up a virtual server.
Once you have determined which Service Port you want to use,
type in the number, then type the last three numbers of that
particular user’s IP address and check Enable. (The available range
is 1-254.)
4.4 Configuring LAN MAC Addresses
The Gateway’s LAN MAC Address Control option gives a
system administrator control over each individual computer’s
network privileges. This feature is also useful as an additional
security measure, because you can restrict access to known
computers on the network. The LAN MAC Address Control
option uses a 12-digit alphanumeric string to uniquely identify each
network hardware device.
The Connection Control item allows control over which clients
have access to the Gateway. You have two choices: allow or deny.
If you deny a client a connection, it cannot access any Internet,
print server, or administrative functions.
Note: The Association Control item is for wireless access only
and is not supported in your IG-4160.
To set up LAN MAC Address Control parameters, follow the
steps below. Refer to the accompanying table if you need additional
information regarding the differences in privileges.
