Certain dialin clients require Windows Internet Naming Service (WINS), and/or Domain Naming System (DNS) server information in order to properly connect to the network. There are also several different mechanisms for delivering IP addresses to dialin clients on access servers.
Ensure that you meet these requirements before you attempt this configuration:
Configure and verify that the router can accept incoming async and ISDN calls. Use the configuration procedure specified in Configuring an Access Server with PRIs for Incoming Multilink Async and ISDN Calls for further information.
Verify that the DHCP, DNS and WINS servers are setup correctly. Contact your system administrator for more information.
Note: This configuration assumes the WINS, DNS, and DHCP servers are different servers. They can in fact be one server, or one server can be running WINS and DNS with DHCP on another box or any other combination of the three.
This configuration was developed and tested using this equipment/devices:
Cisco AS5200 with two T1 PRI circuits
DNS server
WINS server
DHCP server to assign IP addresses to the client
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
This DNS, DHCP and WINS configuration commands can be used on any router that supports incoming PPP calls.
Refer to Cisco Technical Tips Conventions for more information on document conventions.
Some possible options for assigning IP addresses to clients include:
Assigning an address from the local IP pool on the access server.
Using an external Dynamic Host Control Protocol (DHCP) server.
Using Remote Authentication Dial-in User Service (RADIUS) or Terminal Access Controller Access Control System (TACACS+).
This document describes the procedure to pass WINS and DNS server information to the dialin client through the access server. The access server will also pass the IP address returned by an external DHCP server to the dialin client.
