Background/Scenario

In addition to stateful firewall and other security features, the ASA can provide both site -to-site and remote access VPN functionality. The ASA provides two main deployment modes that are found in Cisco SSL remote access VPN solutions:

  • Clientless SSL VPN – A clientless, browser-based VPN that lets users establish a secure, remote-access VPN tunnel to the ASA and use a web browser and built-in SSL to protect VPN traffic. After authentication, users are presented with a portal page and can access specific, predefined internal resources from the portal.
  • Client-Based SSL VPN – A client-based VPN that provides full-tunnel SSL VPN connection, but requires a VPN client application to be installed on the remote host. After authentication, users can access any internal resource as if they were physically on the local network. The ASA supports both SSL and IPsec client-based VPNs.

In Part 1 of this lab, you will configure the topology and non-ASA devices. In Part 2, you will prepare the ASA for ASDM access. In Part 3, you will use the ASDM VPN wizard to configure an AnyConnect client-based SSL remote access VPN. In Part 4 you will establish a connection and verify connectivity.

Your company has two locations connected to an ISP. R1 represents a CPE device managed by the ISP. R2 represents an intermediate Internet router. R3 connects users at the remote branch office to the ISP. The ASA is an edge security device that connects the internal corporate network and DMZ to the ISP while providing NAT services to inside hosts.

Management has asked you to provide VPN access to teleworkers using the ASA as a VPN concentrator. They want you to test the client-based model using SSL and the Cisco AnyConnect client.

Note: The router commands and output in this lab are from a Cisco 1941 router with Cisco IOS Release 15.4(3)M2 (with a Security Technology Package license). Other routers and Cisco IOS versions can be used. See the Router Interface Summary Table at the end of the lab to determine which interface identifiers to use based on the equipment in the lab. Depending on the router model and Cisco IOS version, the commands available and the output produced might vary from what is shown in this lab.

The ASA used with this lab is a Cisco model 5505 with an 8-port integrated switch, running OS version 9.2(3) and ASDM version 7.4(1) and comes with a Base license that allows a maximum of three VLANs.

Instructor Note: AnyConnect Secure Mobility Client release 4.1 or later is recommended. Instructions for installing AnyConnect Client packages to ASA flash are provided in the Chapter 0.0.0.0 lab.

Note: Before beginning, ensure that the routers and switches have been erased and have no startup configurations.

Instructor Note: Instructions for erasing switches and routers are provided in the Chapter 0.0.0.0 lab.

Required Resources

  • 1 ASA 5505 (OS version 9.2(3) and ASDM version 7.4(1) and Base license or comparable)

crypto key generate rsa general-keys modulus 1024

Step 5: Configure PC host IP settings.

Configure a static IP address, subnet mask, and default gateway for PC-A, PC-B, and PC-C as shown in the IP Addressing table.

Step 6: Verify connectivity.

The ASA is the focal point for the network zones, and it has not yet been configured. Therefore, there will be no connectivity between devices that are connected to it. However, PC-C should be able to ping the R1 interface G0/0. From PC-C, ping the R1 G0/0 IP address (209.165.200.225). If these pings are unsuccessful, troubleshoot the basic device configurations before continuing.

Note: If you can ping from PC-C to R1 G0/0 and S0/0/0, you have demonstrated that static routing is configured and functioning correctly.

Step 7: Save the basic running configuration for each router and switch.

Part 2: Accessing the ASA Console and ASDM

Step 1: Clear the previous ASA configuration settings.

a. Use the write erase command to remove the startup-config file from flash memory.

Note: The erase startup-config IOS command is not supported on the ASA.

b. Use the reload command to restart the ASA. This causes the ASA to display in CLI Setup mode. If you see the System config has been modified. Save? [Y]es/[N]o: message, type n, and press Enter.

Step 2: Bypass Setup mode.

When the ASA completes the reload process, it should detect that the startup configuration file is missing and go into Setup mode. If it does not go into Setup mode, repeat Step 2.

a. When prompted to preconfigure the firewall through interactive prompts (Setup mode), respond with no.

b. Enter privileged EXEC mode with the enable command. The password should be kept blank (no password).

Step 3: Configure the ASA by using the CLI script.

In this step, you will use a CLI script to configure basic settings, the firewall , and the DMZ.

a. Use the show run command to confirm that there is no previous configuration in the ASA other than the defaults that the ASA automatically inserts.

b. Enter global configuration mode. When prompted to enable anonymous call-home reporting, respond no.

c. Copy and paste the Pre-VPN Configuration Script commands listed below at the ASA global configuration mode prompt to start configuring the SSL VPNs.

Observe the messages as the commands are applied to ensure that there are no warnings or errors. If prompted to replace the RSA key pair, respond yes.

Step 11: Verify the AnyConnect client profile.

After the configuration is delivered to the ASA, the AnyConnect Connection Profiles screen displays.

Part 4: Connecting to an AnyConnect SSL VPN

Step 1: Log in from the remote host.

a. Initially, you will establish a clientless SSL VPN connection to the ASA in order to download the AnyConnect client software. Open a web browser on PC-C. In the address field of the browser, enter https://209.165.200.226 for the SSL VPN. SSL is required to connect to the ASA, therefore, use secure HTTP (HTTPS).

b. Enter the previously created username REMOTE-USER with the password cisco12345. Click Logon to continue.

Note: The ASA may request confirmation that this is a trusted site. If requested, click Yes to proceed.

Step 2: Perform platform detection (if required).

If the AnyConnect client must be downloaded, a security warning will display on the remote host. The ASA will detect whether ActiveX is available on the host system. In order for ActiveX to operate properly with the Cisco ASA, it is important that the security appliance is added as a trusted network site.

Note: If ActiveX is not detected, the AnyConnect client software must be manually downloaded and installed. Skip to Step 3 for instructions on how to manually download the AnyConnect client software.

a. The ASA will begin a software auto-download process consisting of a series of compliance checks for the target system. The ASA performs the platform detection by querying the client system in an attempt to identify the type of client connecting to the security appliance. Based on the platform that is identified, the proper software package may be auto-downloaded.

b. If you are presented with the AnyConnect Downloader window that indicates the 209.165.200.226 AnyConnect server could not be verified, click the Change Setting button.

c. The AnyConnect Downloader will present a verification window to change the setting that blocks untrusted connections. Click Apply Change.

d. If you receive the Security Waning: Untrusted Server Certificate message, Click Connect Anyway.

e. The AnyConnect Secure Mobility Client Downloader window counts down the download time.

f. After the download is complete, the software will automatically start to install. Click Yes when asked to allow the program to make changes to the computer.

g. When installation is complete, the AnyConnect client will establish the SSL VPN connection.

h. If the Connected option in the panel on the left is checked, skip to Step 5. If the Connect option is not checked, continue to Step 3.

Step 3: Install the AnyConnect VPN Client (if required).

If ActiveX is not detected, the AnyConnect client software must be manually downloaded and installed.

a. On the Manual Installation screen, click Windows 7/Vista/64/XP.

b. Click Run to install the AnyConnect VPN client.

c. After the download is complete, the Cisco AnyConnect VPN Client Setup starts. Click Next to continue.

d. Read the End-User License Agreement. Select I accept the terms in the License Agreement and click Next to continue.

e. The Ready to Install window is displayed. Click Install to continue.

Note: If a security warning is displayed, click Yes to continue.

f. Click Finish to complete the installation.

Step 4: Establish an AnyConnect SSL VPN Connection.

a. When the AnyConnect VPN client has been installed, manually start the program by clicking Start > Cisco AnyConnect VPN Client

b. When prompted to enter the secure gateway address, enter 209.165.200.226 in the Connect to field, and click Select.

Note: If a security warning is displayed, click Yes to proceed.

c. When prompted, enter REMOTE-USER for the username and cisco12345 as the password.

Step 5: Confirm VPN connectivity.

When the full tunnel SSL VPN connection is established, an icon will appear in the system tray that signifies that the client has successfully connected to the SSL VPN network.

a. Display connection statistics and information by double-clicking the AnyConnect icon in the system tray.You will be able to disconnect the SSN VPN session from here. Do Not click Disconnect at this time. Click the gear icon at the bottom left corner of the Cisco AnyConnect Secure Mobility client window.

b. Use the scroll bar on the right side of the Virtual Private Network (VPN) – Statistics tab for additionalconnection information.

Note: The inside IP address that is assigned to the client from the VPN pool is 192.168.1.100-125.

c. From a command prompt on the remote host PC-C, verify the IP addressing by using the ipconfigcommand. Notice that there are two IP addresses listed. One is for the PC-C remote host local IP address(172.16.3.3) and the other is the IP address assigned to the SSL VPN tunnel (192.168.1.100).

d. From remote host PC-C, ping PC-B (192.168.1.3) to verify connectivity.

Step 6: Use the ASDM Monitor to view the AnyConnect remote user session.

Note: Future SSL VPN sessions can be launched through the web portal or through the installed Cisco AnyConnect SSL VPN client. While the remote user at PC-C is still logged in using the AnyConnect client, you can view the session statistics by using the ASDM monitor.

On the ASDM menu bar, click Monitoring and then select VPN > VPN Statistics > Sessions. Click the Filter By pull-down list and select AnyConnect Client. You should see the VPN-User session logged in from PCC, which hasbeen assigned an inside network IP address of 192.168.1.100 by the ASA.

Note: You may need to click Refresh to display the remote user session.

Reflection

1. Describe at least two benefits of client–based vs. clientless VPNs?
_______________________________________________________________________________________
_______________________________________________________________________________________
_______________________________________________________________________________________
_______________________________________________________________________________________
_______________________________________________________________________________________
Users have access to the same internal network resources as if they were on the LAN. Client-based VPN solutions, such as AnyConnect, can be configured to automatically download the proper client software based on the client platform characteristics.

2. Describe at least one difference between using SSL compared to IPsec for remote access tunnel encryption?
_______________________________________________________________________________________
_______________________________________________________________________________________
_______________________________________________________________________________________
_______________________________________________________________________________________
Client-based VPNs can offer a more secure tunnel, if using IPsec, but are somewhat more complex to configure.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
