Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is a
network-layer protocol used to establish membership in a Multicast group - it is not
used to carry user data.
Select IGMP-v1 or IGMP-v2. IGMP version 2 (RFC 2236) is an improvement over
version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read
more detailed information about interoperability between IGMP version 2 and version
1, please see sections 4 and 5 of RFC 2236.
Select CISCO PPP from the drop-down list box if your backup WAN device uses
Cisco PPP encapsulation; otherwise select Standard PPP.
Select this check box to enable stac compression.
Select Nailed-Up Connection when you want your connection up all the time. The
Prestige will try to bring up the connection automatically if it is disconnected.
Select Connect on Demand when you don't want the connection up all the time and
specify an idle time-out in the Max Idle Timeout field.
Specify an idle time-out in the Max Idle Timeout field when you select Connect on
Demand. The default setting is 0, which means the Internet session will not timeout.
The configuration in the Budget fields has priority over your Connection settings.
Type the amount of time (in minutes) that the dial backup connection can be used
during the time configured in the Period field. Set an amount that is less than the
time period configured in the Period field. If you set the Allocated Budget to 0, you
will not be able to use the dial backup connection.
Type the time period (in hours) for how often the budget should be reset. For
example, to allow calls to this remote node for a maximum of 10 minutes every hour,
set the Allocated Budget to 10 (minutes) and the Period to 1 (hour). If you set the
Period to 0, there is no budget control and the Prestige uses the Connection
settings.
