Leave the Telnet session open. Step 11: Display CBAC inspection sessions. Display the IP inspect session to see the active Telnet session from PC-A to R2. R1 show ip inspect sessions Established Sessions Session 6576FE20 192.168.1.3:1045=10.1.1.2:23 tcp SIS_OPEN Session Task 9: Configure a ZBF Firewall on R3 Chapter 4 Step 1: Use CCP to discover R3. a. Run the CCP application on PC-C. In the SelectManage Community window, input the R3 IP address 192.168.3.1 in the first IP AddressHostname field. Enter admin in the Username field, and cisco12345 in the Password field. Click on the OK button. b. At the CCP Dashboard, click on the Discovery button to discover and connect to R3. If the discovery process fails, use the Discover Details button to determine the problem in order to resolve the issue. Step 2: Use the CCP Firewall wizard to configure a ZBF on R3. a. Click the Configure button at the top of the CCP screen, and then click Security Firewall Firewall. b. Select Basic Firewall and click the Launch the selected task button. On the Basic Firewall Configuration wizard screen, click Next. c. Check the Inside trusted check box for Fast Ethernet01 and the Outside untrusted check box for Serial001. Click Next. Click OK when the CCP access warning is displayed. d. Choose Low Security and click Next. In the Summary window, click Finish. e. Click OK in the Commands Delivery Status window. Step 3: Verify ZBF functionality. a. From PC-C, ping the R2 interface S001 at IP address 10.2.2.2. C:\ ping 10.2.2.2 Are the pings successful? Why or why not? Yes. ICMP echo replies are allowed by the sdm-permit- icmpreply policy. b. From external router R2, ping PC-C at IP address 192.168.3.3 R2 ping 192.168.3.3 Are the pings successful? Why or why not? No. The ping was initiated from outside and was blocked. c. From router R2, Telnet to R3 at IP address 10.2.2.1. R2 telnet 10.2.2.1 Trying 10.2.2.1 ... Connection timed out; remote host not responding Is the Telnet attempt successful? Why or why not? No. Telnet was initiated from outside R3 S001 and was blocked.

From PC-C on the R3 internal LAN, Telnet to R2 at IP address 10.2.2.2 and use password ciscovtypass. C:\ telnet 10.2.2.2 User Access verification Password: ciscovtypass e. With the Telnet session open from PC-C to R2, issue the command show policy-map type inspect zone-pair session on R3. Continue pressing Enter until you see an Inspect Established session section toward the end. R3 show policy-map type inspect zone-pair session output omitted Inspect Number of Established Sessions = 1 Established Sessions Session 6578550 192.168.3.3:3443=10.2.2.2:23 tacacs:tcp SIS_OPEN Created 00:00:38, Last heard 00:00:22 Bytes sent initiator:responder [45:235] Step 4: Save the running configuration to the startup configuration. Task 10: Configure Intrusion Prevention System IPS on R1 Using Cisco IOS Chapter 5 Step 1: Optional Install the TFTP server on PC-A. If a TFTP server is not currently installed on PC-A, download Tftpd32 from http:tftpd32.jounin.net and install it on your desktop. If it is already installed, go to Step 2. Step 2: Prepare the router and TFTP server. To configure Cisco IOS IPS 5.x, the IOS IPS Signature package file and public crypto key files must be available on PC-A. Check with your instructor if these files are not on the PC. These files can be downloaded from Cisco.com with a valid user account that has proper authorization. a. Verify that the IOS-Sxxx-CLI.pkg signature package file is in a TFTP folder. The xxx is the version number and varies depending on which file was downloaded. b. Verify that the realm-cisco.pub.key.txt file is available and note its location on PC-A. This is the public crypto key used by IOS IPS. c. Verify or create the IPS directory in router flash on R1. From the R1 CLI, display the content of flash memory using the show flash command. Check whether the ipsdir directory exists and if it has files in it. R1 show flashd. If the ipsdir directory is not listed, create it.
