Configuring Demand Routing for Primary ISDN Modules
Using Demand Routing for ISDN Connections
To define the interesting traffic, you create an extended ACL. The ProCurve
Secure Router will use this ACL to identify and select traffic that triggers a
dial-up connection.
From the global configuration mode context, enter:
Syntax: ip access-list extended <listname>
Replace <listname> with an alphanumeric descriptor that is meaningful to
you. The listname is case sensitive.
After you enter this command, you are moved to the extended ACL configu-
ration mode context, as shown below:
ProCurve(config-ext-nacl)#
You can now enter permit statements to define the traffic that will trigger the
dial-up connection. Use the following command syntax:
Syntax: [permit | deny] <protocol> <source address> <source port> <destination
address> <destination port> [log | log-input]
You must specify a <protocol>, <source address>, and <destination
address>. However, the following are optional:
■ <source port> for TCP or UDP traffic
■ <destination port> for TCP or UDP traffic
■ [log | log-input]
Specifying a Protocol
When you create a permit or deny statement for an extended ACL, you must
always specify a protocol. Valid protocols include:
■ AHP
■ ESP
■ GRE
■ ICMP
■ IP
■ TCP
■ UDP
You can also specify the number of the protocol. Valid numbers include any
number between 0 and 255.
