Create an Access List
To specify the access conditions, restrict incoming and outgoing con-
nections between a particular Virtual Terminal (VTY) line (into a
Cisco access server) and the addresses in an access list by typing (in
global configuration mode):
x29 access-list
access-list-number
{deny |
permit}
x121-address
An access list can contain any number of lines. The lists are processed
in the order in which you type the entries. The first match causes the
permit or deny condition. If an X.121 address does not match any of
the entries in the access list, access is denied.
Example: X.29 Access List
This example illustrates an X.29 access list. Incoming permit condi-
tions are set for all IP hosts that have specific characters in their names.
All X.25 connections to a printer are denied. Outgoing connections are
list restricted.
Permit all IP hosts beginning with VMS. Deny X.25 connections to th
printer on line 5.
access-list 1 permit 0.0.0.0 255.255.255.255
lat access-list 1 permit ^VMS.*

Permit outgoing connections for other lines. Permit IP access with the
network 172.30.
