Communication Applications

Most applications are supported transparently by the TW100-BRV304. But sometimes it is not

connection, as described below.

Select an Application

This lists the PCs on your LAN.

•

If necessary, you can add PCs manually, using the "PC

Database" option on the advanced menu.

•

For each application listed above, you can choose a destina-

tion PC.

•

There is no need to "Save" after each change; you can set the

destination PC for each application, then click "Save".

Special Applications

If you use Internet applications which use non-standard connections or port numbers, you may

find that they do not function correctly because they are blocked by the TW100-BRV304 's

firewall. In this case, you can define the application as a "Special Application".

Special Applications Screen

This screen can be reached by clicking the

Special Applications

button on the

Advanced

Internet

screen.

You can then define your Special Applications. You will need detailed information about the

application; this is normally available from the supplier of the application.

client (PC) viewpoint
