v Click Routing to open the Routing dialog.
v For static routing, specify Add remote system as the default route. Since you
do not know the range of destination IP addresses, you need a default route.
This is the desired configuration when AS/400 dials in to an ISP such as IGN.
The default route forwards packets to the ISP router, which in turn routes the
packets throughout the Internet.
Click the Authentication tab.
v Check ″Enable local system identification.″ IGN requires customers to use the
Password Authentication Protocol (PAP) for authentication. This verifies the
identity of the customer who is using an unencrypted password.
v Specify both a user ID and a password. In this example, the user name is
internet.account.userid. Other ISPs may use CHAP, which uses an encrypted
password. Consult your ISP to learn its requirements for specifying a user name
and password.
Click the Domain Name Server tab.
v Specify the IP address for the Domain Name Server. In this example, the IP
address is 10.11.27.5. When you use an Internet Service Provider (ISP) to
connect to the Internet, you will receive a name server address from the ISP.
This allows you to connect using host names instead of IP addresses for remote
sites. A host name is a way of identifying a system and its IP address.
Example: Connecting two AS/400s using dial-on-demand
In this example, System 1 is a local system with IP address 10.11.25.1 and System
2 is a remote system with IP address 10.11.25.2. To establish a connection:
1. Configure a Dial-only connection profile on System 1.
2. Configure a Switched line-answer connection profile on System 2.
3. Start connection profiles on System 1 and System 2 by using Operations
Navigator.
4. Verify configurations on System 1 and System 2 by using TELNET.
Configure a Dial-only connection profile on System 1
1. Access Point-to-Point functions through Operations Navigator.
2. From New Point-to-Point Profile Properties dialog, click the General tab and
do the following:
v Type DODBP in the Name text box.
v Type Basic Dial on Demand Profile in the Description text box.
v Under Type, select PPP.
v Under Mode, select Dial-on-demand (dial only).
3. Click the Connection tab and do the following:
v Type the phone number of the remote system.
v Under Line, select a line pool from the Name list.
v Select Override line activity timeout and specify 300 seconds, or five
minutes, as the Timeout value.
4. Click the TCP/IP Settings tab and then do the following:
v Under Local IP Address, click the radio button and type 10.11.25.1 in the
text box.
v Under Remote IP Address, the Remote IP Address is 10.11.25.2.
