Otherwise, see the section later in this chapter on Setting Up Telnet Operation for information on setting the server to allow Telnet access from hosts on its network. Temporarily Reconfiguring a Host for Command Line Management You can temporarily reconfigure an IP host in order to set the server’s IP parameters to allow in-band Telnet access. If you wish to set the server’s basic IP parameters in this fashion, the host must be on the same Ethernet segment as one of the server’s Ethernet interfaces. You can then do the following: 1. Set the host’s IP address to 198.41.12.2, with a Class C subnet mask (255.255.255.0) and then Telnet to 198.41.12.1. 2. Enter the default password letmein at the password prompt. The command line interface prompt will appear on the screen. 3. Use the configure command and set the IPAddress, SubnetMask, and IPBroadcast keywords in the IP Ethernet 0:0 section. 4. Use the save command to save the changes to the device’s Flash ROM. 5. Change the host’s configuration back to its original settings. See the next section (Setting Up Telnet Operation) for information on setting the server to allow Telnet access from hosts on its network. Chapter 5 - Command Line Management Setting Up Telnet Operation Telnet is a remote terminal communications protocol based on TCP/IP. With Telnet you can log into and manage the IntraPort Enterprise-8 from anywhere on your IP internetwork, including across the Internet if your security setup allows it. To manage the server with Telnet, you must: 1. Run Telnet client software on your local computer, which will communicate with the Telnet server built into the IntraPort Enterprise-8. 2. You must also set some basic IP parameters in the server. The required parameters for Telnet access to an interface are the IP address, IP subnet mask, and IP broadcast address. There are several ways to set them. • You may set them using text-based configuration either out-of-band via the Console interface or in-band via a reconfigured IP host. Instructions for setting up these two methods were given earlier in this chapter. Once you have set up the command line interface, do the following: A. Use the configure command and set the IPAddress, SubnetMask, and IPBroadcast keywords in the IP Ethernet 0:0 section. B. Use the save command to save the changes to the device’s Flash ROM. • You may also use CompatiView from a reconfigured IP host (if using the IP transport protocol), or anywhere on your network (if using the IPX transport protocol). Instructions for these two methods are given in Chapter 4 - CompatiView Software Installation. With CompatiView, basic IP parameters can be set using the TCP/IP Routing: Ethernet 0:0 Dialog Box. Use the Save to/Device option under the File menu to save the changes. After you have set these IP parameters and saved the changes, you can use Telnet to access the server from any node on your IP network. Invoke the Telnet client on your local host with the IP address of the server you wish to manage. Chapter 6 - Basic Configuration Guide Chapter 6 - Basic Configuration Guide This chapter briefly discusses the major parameters that must be set in order to use the IntraPort Enterprise-8 VPN Access Server. Detailed information on the meaning of the server’s parameters is provided in the Compati- View Management Software Reference Guide and the Text-Based Configuration and Command Line Management Reference Guide. You should use this list as a starting point to look up more specific information in the other documents. There are a number of parameter settings which are optional, in the sense that they are not required for all installations. These settings are not covered in this chapter. In this chapter: CV = CompatiView TB = Text-Based Configuration • Note: This Basic Configuration Guide does not include information on setting up packet filters. See the CompatiView Management Software Reference Guide or Text-Based Configuration and Command Line Management Reference Guide regarding IP, IPX and AppleTalk packet filters for more information. Ethernet Interface Configuration As shown in Figure 11: Detail of RIOP Cards, the IntraPort Enterprise-8’s RIOP cards have specialized functions. The even-numbered slots (0, 2, 4 and 6) feature full IP, IPX and Apple- Talk router ports, while the odd-numbered slots (1, 3, 5 and 7) feature IPSec-only interfaces. These ports can only send and receive IPSec packets. All other traffic is dropped. Thus, Ethernet 0:0, 2:0, 4:0, and 6:0 can be thought of as internal/private ports and Ethernet 1:0, 3:0, 5:0 and 7:0 can be thought of as external/public ports. If you have physically installed your IntraPort Enterprise-8 using both types of ports, then you should follow the IP Settings for Setups in Parallel with a Firewall. If you have physically installed your IntraPort Enterprise-8 behind your firewall using the Ethernet interfaces on slots 0, 2, 4, and 6 only, then you should follow the IP Settings for Setups Behind a Fi...
