Port, and TCP Connection establishment. Go to the Profiles
>
Filters window
to create tunnel filters.
13 Select Enable to enable IPX support for the group.
14 Enter the maximum number of PPP links in Maximum Number of Links
field that you want the Nortel VPN Router to support. The range is 1 to 5;
default is 1. The Multilink PPP (MP) implementation allows tunneling
multilink connections to the Nortel VPN Router when the tunneling is being
done by the ISP.
15
RSVP allows you to signal the network for required bandwidth. The client
must be configured appropriately for RSVP to work. Also, only the controlled
load-service is supported. This option is disabled by default.
16 The Token Bucket Depth influences packet flow delays within the Nortel
VPN Router and participating routers in the Internet. The largest amount of
data the Nortel VPN Router holds in its queue determines latency. New
packets arriving are delayed by a time that is proportional to the amount of
traffic that is ahead of them in the queue, which is no greater than the Token
Bucket Depth. When the queue exceeds the Token Bucket Depth, incoming
packets are dropped. To guarantee reduced latency, the Bucket Depths should
be small. Typically, you should not change this setting. Default is 3000 bytes.
17
The Token Bucket Rat e is the highest long-term average data rate (in Kbps)
required over time for the connection. It informs the Nortel VPN Router and
participating routers in the Internet how much bandwidth to reserve for the
RSVP session. Typically, you should not change this setting. Default is 28
Kbps.
18 Click on the drop-down menu to select the Address Pools used by remote
users to access this Nortel VPN Router. The drop-down list shows all pools
that have been defined on the Nortel VPN Router. (Address pools are defined
on the Servers > User IP Addr window). Select the
New Address Pool link to
define a new pool. Refer to “Remote User IP Address Pool” for details. This
option is set to Default Pool by default.
19 In the User Bandwidth Policy section you modify bandwidth characteristics
for this group.
a
Select a Committed Rate from the list of available bandwidth rates. If the
desired bandwidth rate is not listed, click on Define new bandwidth rate to
create a new one.
b
Select an Excess Rate from the list.
