Tunnels are normally initiated
On Demand
; however, you can disable this feature. When disabled, the
tunnel must be manually established or may be scheduled using the scheduled connections feature. See
"Scheduled Connections" on page 2-16
.
•
You can specify the
Idle Timeout
(in seconds), an inactivity timer, whose expiration will terminate the
tunnel. A value of zero disables the timer. Because tunnels are subject to abrupt termination when the
underlying datalink is torn down, use of the Idle Timeout is strongly encouraged.

About GRE Tunnels
Generic Routing Encapsulation (GRE) protocol is another form of tunneling that Motorola Netopia
®
routers
suppor t. A GRE tunnel is brought up when a valid GRE profile is installed, and brought down when the profile is
disabled, or deleted.
GRE tunnels are not
connection-based
, but rather are installed and simply wait for GRE packets. There is no
special star tup initiation as with PPPoE or PPTP. GRE is best adapted to simple routing and/or tunneling, and is
not for use with any sensitive data. GRE offers no encr yption; and authentication of data integrity is limited to
checksum verification, if enabled.
To set up a GRE tunnel, you create a Connection Profile including the IP address and other relevant information
for the remote par tner.
