Tunneling does not affect the local network; you may add as many workstations
as the local network supports. However there is an upper limit to the number of
simultaneous outbound connections.
Unlike bridging, a PPP/ATM channel cannot be shared by multiple users. Every
local user establishing a tunnel requires an ATM channel on the network.
Therefore, any user on the local network can create a tunnel as long as unused
ATM channels are available.
By default, the modem supports eight PPP/ATM channels. If all PPP/ATM
channels are in use and a user tries to create a new tunnel, the modem refuses
the request and an error message appears on the screen.

In the PPTP Destination Table, you can determine which destination
each tunnel is associated with.

TCP/IP is used to establish PPTP tunnels between local workstations and the
modem. The data transported end-to-end may be TCP/IP, IPX/SPX, or NetBEUI.
The limitations are not caused by the tunneling protocol or the ATM connection,
but are a function of the PPTP client.
Currently, Windows 95, Windows 98, and Windows NT support three protocols in
the tunnel. All three can be disabled individually.
