Level One ISDN Router
Internet Applications
These features, on the Internet Application tab, are not available if you use the
ISDN Router for LAN-to-LAN connection.
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 the more
common applications have been pre-defined, and will appear in the list.
•
If a new Internet application is unable to function correctly, you can add it to
the list.
•
At any time, each Special Application can be used by only 1 PC.
Virtual Servers
The Virtual Servers feature allows Internet users to access standard Servers on
your LAN, via the Level One ISDN Router.
Normally, Internet users would not be able to access a server on your LAN
because:
•
Your Server does not have a valid external IP Address.
•
Attempts to connect to devices on your LAN are blocked by the firewall in the
Level One ISDN Router.
The "Virtual Server" feature solves these problems and allows Internet users to
connect to your servers. However, your LAN must have an existing connection to
the Internet. Internet users cannot open a connection.
To Internet users, all virtual Servers on your LAN have the same IP Address (IP
Address from ISP, on the Quick Setup screen). This address should be fixed (static)
to make it easier for Internet users to connect to your Servers.
Exposed PC
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all
users on the Internet, allowing unrestricted 2-way communication between the
"Exposed Computer" and other Internet users or Servers.
