Special Applications
This feature is only required if you wish to use Internet applications which require
2-way communication, multiple connections, or combined TCP/UDP connections.
Examples of such applications are Internet Videoconferencing, Telephony, Games
Servers, and other special-purpose Servers. A number of "Special Applications" are
already defined, and listed on the Special Apps tab.
Generally, you will become aware of the need for this feature when an Internet ap-
plication is unable to function correctly.
To enable an existing Special Application:
•
Select it from the list
•
Check the Enable checkbox
•
Click Update.
To change an existing Special Application:
•

•
Make the required changes in the Properties fields. (The on-line help pro-
vides details about each of the Properties fields.)

To Add a new Special Application

Note that some Special Applications do not use both "Incoming" and "Outgo-
ing" Protocols and Port Numbers. In this case, leave the port numbers blank for
the unused section, and select "Auto" for the protocol.
If only a single port number is required for either "Incoming" or "Outgoing",
enter it in the Start field, and leave the Finish port number blank.
PC Configuration for Special Applications
Once PCs are configured for Internet Access, no changes are required for these Spe-
cial Applications. Just install, configure, and use the desired program according to
