Configure an IP Tunnelling Network

IP tunnelling provides clients with access to NetWare servers that are connected over TCP/IP networks.

A maximum of 16 remote systems (peers that are either NetWare servers or clients performing IP tunnelling directly) can be accessed from the NetWare 9000 server using IP tunnelling.

NetWare 9000 provides IP tunnelling primarily for the purpose of limited wide area network communications over TCP/IP. Although IP tunnelling can be performed from PCs (for example, using Novell's LAN Workplace software) typically, it is intended for tunnelling between servers.

NetWare 9000 does not provide dynamic IP tunnel attachment by default: all peer systems must be configured for IP tunnelling in SAM, as described in this section.

Figure 8-1 shows an example network where IP tunnelling configuration can be used for a NetWare PC client (attached to Server 1) to access files on NetWare 9000 Server 2. The NetWare PC client shown in Figure 8-1 can map local drives to NetWare volumes on NetWare 9000 Server 2 only if IP tunnelling is active on both NetWare servers 1 and 2.

Figure 8-3 IP Tunnelling Example

With NetWare 4.1/9000, you can configure your NetWare server to support IP tunnelling as the only network, without using a default NetWare network as shown in Figure 7-2.

The NetWare PC clients can map local drives to NetWare volumes on NetWare Server 2 only if IP tunnelling is activated on both NetWare servers 1 and 2. In this environment, there is no need to run the IPX/SPX protocol stack on NetWare Server 2.

Adding an IP Tunnelling Network

To configure IP routing of IPX packets, you create an IP tunnelling network between NetWare 9000 systems that will communicate using IP. To configure IP tunnelling:

1. Complete the IP Tunnelling Address Mapping Worksheet (see below).

2. For each system:

   • Configure the IP Tunnelling network.

   • Configure the IP address mapping for that system.

3. Restart NetWare on each system.

Each step is described in the sections following.

IP Tunnelling Worksheet

An IP Tunnelling Worksheet has been provided to help you configure your network.

Complete the Worksheet:

1. Pull out a copy of the IP Tunnelling Worksheet from this guide (from this chapter, or Appendix A). Make copies for each system that will be configured as part of the IP tunnelling network.

2. Obtain the host name and IP address for your local system and write it on the worksheet.

3. Obtain the host name or IP addresses for all remote systems you want to access using IP tunnelling.

4. Complete the worksheet for each system.

   If the IP socket used for a particular system is different than 213, make a note of it on the worksheet.

   	NOTE: Do not change the IP socket number unless absolutely necessary.

IP Tunnelling Network Configuration

1. Log into the system as root.

2. At the HP-UX prompt, type: sam

3. Double click Networking and Communications at the SAM main window.

4. Double click NetWare at the Networking and Communications window.

5. Double click Networking Configuration at the NetWare window.

6. Add IP Tunnelling. Choose Set Up IP Tunnelling from the "Actions" menu.

   1. Enter the information about the network. To do so, press the Tab key to move through the data entry fields.

   2. Select the LAN card from the list of Host Interface names.

      1. The NetWare autodiscovery feature will list the IPX networks to which you can connect.

      2. Select the IPX network you want from the list.

   3. Enter the external Network Address of your network. This new number specifies a unique number designating the address for the network.

   4. Then add the Host Name or IP Address of the network you want to connect to. This host name or IP address will be displayed in the list of Peer Assignments in the middle of the screen.

   5. Activate the Add button to perform the task(s) and return to the Networking Configuration Window.

   6. Repeat this procedure for each system on the IP tunnelling network.

7. Complete the IP Tunnelling Worksheet in this chapter noting the default values that you used. You will need this information for future network.

8. After you have updated your completed the worksheet, return to the NetWare menu in SAM.
