This document describes how to configure AnyConnect VPN (Virtual Private Network) on an FTD (Firepower Threat Defense) firewall using Cisco ISE (Identity Services Engine) as a RADIUS server. We use a Windows Server 2012 as our Root CA (Certificate Authority) so that the communication over VPN is secured by certificates i.e. the employee PC will trust the certificate of the FTD because the FTD VPN certificate has been signed by our Windows Server 2012 Root CA
You must have the following deployed and running in your network:
In our example below, employees will open the AnyConnect Client on their Windows/Mac PC, and they will securely connect to the outside interface of the FTD via VPN using their credentials. The FTD will check their username and password against Cisco ISE (which will check with Windows Server Active Directory to verify their username, password, and group i.e. only users in the AD Group 'Employees' will be able to VPN into the company network.
The information in this document is based on these software versions:
In this use case, the employee's Windows/Mac PC running the Anyconnect VPN Client will connect to the outside public IP address of the FTD firewall, and Cisco ISE will dynamically grant them limited or full access to certain internal or internet resources (configurable) once they are connected via VPN depending on what AD Group they are a member of in Active Directory
Device | Hostname/FQDN | Public IP Address | Private IP Address | AnyConnect IP Address | |
Windows PC | - | 198.51.100.2 | 10.0.0.1 | 192.168.10.50 | |
FTD | ciscofp3.cisco.com | 203.0.113.2 | 192.168.1.1 | - | |
FMC | - | - | 192.168.1.30 | - | |
Cisco ISE | ciscoise.cisco.com | - | 192.168.1.10 | - | |
Windows Server 2012 | ciscodc.cisco.com | - | 192.168.1.20 | - | |
Internal Servers | - | - | 192.168.1.x | - |
In this document, we will use Microsoft Windows Server 2012 as our Root CA for certificates. The Client PC's will trust this Root CA to connect securely to the FTD via VPN (see steps below). This will make sure they can connect securely to the FTD over the internet and access internal resources from home. Their PC will trust the connection in their browser and AnyConnect Client.
Go to http://192.168.1.20/certsrv and follow the below steps to download your Windows Server Root CA Certificate:
Click Download a CA certificate, certificate chain, or CRL
Click Download Certificate and rename it to 'RootCAcert3.cer'
Method 1: Install the certificate on all employee PC's by pushing it via Windows Server Group Policy (ideal for anything over 10 VPN users):
How to use Windows Server to Distribute Certificates to Client Computers by Using Group Policy
Method 2: Install the certificate on all employee PC's by installing it individually on each PC (ideal to test one VPN user):
Right-click the certificate on your employees' Windows/Mac PC and click Install Certificate
Select 'Current User'
Select Place all certificates in the following store and select Trusted Root Certification Authorities, click Ok, click Next, and click Finish
Go to Objects > Object Management > PKI > Cert Enrollment, click on Add Cert Enrollment

Download and install Cisco AnyConnect Profile Editor
Open AnyConnect Profile Editor
Click Server List > click Add...
Type a Display Name and the FQDN of your FTD's outside interface IP address. You should see entries in Server List
Click OK and File > Save as...
Download Windows and Mac .pkg images from here
Go to Objects > Object Management > VPN > AnyConnect File > click Add AnyConnect File
Login to the FirePOWER Management Center
Click System > Integration > Realms > click New Realm >> click Directory tab > click Add directory
Click Realm Configuration tab - configure your domain controller's info here
Note: In the above example, an AD username with 'Domain Admin' privileges in the Windows AD Server is used. If you want to configure a user with more specific, minimum permissions for the FMC to join your Active Directory Domain for your Realm configuration, you can see the steps here
Click User Download tab - make sure User Download succeeds
Click Devices > VPN > Remote Access > click Add
Type a Name, Description, and click Add to select the FTD device which you want to configure Anyconnect VPN on
Click Add for the Authentication Server and choose RADIUS Server Group - this will be your Cisco Identity Services Engine PSN (Policy Services Node)
Type a Name for the RADIUS server
Select your Realm configured above
Click Add
Type the following info for your Cisco ISE node:
IP Address/Hostname: IP Address of Cisco ISE PSN (Policy Service Node) - this is where authentication requests will go
Key: cisco123
Confirm Key: cisco123
Caution: the above is your RADIUS Shared Secret key - we will use this key in a later step
Note: When the end user attempts to connect to the FTD via AnyConnect VPN, the username + password they type will be sent as an authentication request to this FTD. The FTD will forward that request to the Cisco ISE PSN node for authentication (Cisco ISE will then check Windows Active Directory for that username and password, and enforce access control/network access depending on the condition we have currently configured in Cisco ISE)
Click Save
Click Edit for IPv4 Address Pool
Click Add
Type a Name, IPv4 Address Range, and Subnet Mask
Select your IP address pool and click Okay
Click Edit Group Policy
Click Anyconnect tab > Profiles > click Add
Type a Name and click Browse… and select your VPNprofile.xml file from step 4 above
Click Save and click Next
Select the checkboxes for your AnyConnect Windows/Mac file from step 4 above
Click Next
Select Interface Group/Security Zone as Outside
Select Certificate Enrollment as your certificate we made in step 3 above
Review your configuration and click Next
Create a static NAT rule to make sure the VPN traffic does not get NAT'd (FTD already decrypts the AnyConnect packets as they come to the Outside interface, so it is as if that PC is already behind the inside interface, and they already have a private IP address - we still need to configure a NAT-Exempt (No-NAT) rule for that VPN traffic):
Go to Objects > click Add Network > click Add Object
Additionally, you must Allow the data traffic to flow after the user VPN's in. You have two choices for this:
a. Create Allow or Deny rules to Allow or Deny VPN users to access certain resources
b. Enable 'Bypass Access Control Policy for decrypted traffic' - this lets anyone who is able to successfully connect to the FTD via VPN bypass ACL's and access anything behind the FTD without going through Allow or Deny rules in Access Control Policy
Enable Bypass Access Control Policy for decrypted traffic under: Devices > VPN > Remote Access > VPN Profile > Access Interfaces:
Note: If you do not enable this option, you will need to go to Policies > Access Control Policy and create Allow rules for the VPN users to be able to access things behind inside or dmz
ClickDeployin the top-right of the FirePOWER Management Center
Login to Cisco Identity Services Engine and click Administration > Network Devices > click Add
Type a Name, type the IP Address of your FTD, and type your RADIUS Shared Secret from the steps above
Caution: This must be the interface/ip address out which the FTD can reach your Cisco ISE (RADIUS Server) i.e. the FTD interface which your Cisco ISE can reach the FTD over
Click Policy > Policy Set > create a Policy Set for any authentication requests that come in of the following type:
Radius-NAS-Port-Type EQUALS Virtual
This means if any RADIUS requests that come into ISE that look like VPN connections, they will hit this Policy Set
Here's where you can find that condition in Cisco ISE:
Edit the Policy Set you created above
Add a rule above the default block rule to give people 'Permit Access' authorization profile only if they are in the Active Directory Group called 'Employees':
Below is how your rule will look once complete
Open your browser on the employee Windows/Mac PC, and go to the outside address of your FTD in your browser
Type your Active Directory username and password
Click Download
Install and Run AnyConnect VPN Secure Mobility Client on Windows/Mac PC
Type your Active Directory username and password when prompted
You will be given an IP address from the IP Address Pool created above in step 5 and a Default Gateway of the .1 in that subnet

Capture taken on the employee PC of the PC successfully connecting to the FTD via AnyConnect VPN
You can also see the DTLS tunnel forming later in this same capture
Capture taken on the Outside interface of the FTD showing the AnyConnect PC successfully connects to VPN
Note: you can see the FTD VPN Server certificate in the 'Server Hello' packet as we connect to the outside interface of the FTD via VPN. The employee PC will trust this certificate because the employee PC has the Root CA certificate on it, and the FTD VPN Server certificate was signed by that same Root CA.
Capture taken on the FTD of the FTD asking RADIUS Server if username + password are correct (Cisco ISE)
As you can see above, our VPN connection gets an Access-Accept, and our AnyConnect VPN Client successfully connects to the FTD via VPN
Capture (CLI) of FTD asking Cisco ISE if username + password are valid (i.e. make sure RADIUS requests are successfully going between FTD and ISE and verify out which interface are they leaving)

DART bundle
How to collect the DART bundle for AnyConnect
Verify Cisco ISE, FTD, Windows Server 2012, and Windows/Mac PCs can all resolve eachother forward and reverse (check DNS on all devices)
Windows PC
Launch a command prompt, and make sure you can perform an 'nslookup' on the hostname of the FTD
FTD CLI
>show network
> nslookup 192.168.1.10 Server: 192.168.1.10 Address: 192.168.1.10#53 10.1.168.192.in-addr.arpa name = ciscoise.cisco.com
ISE CLI:
ciscoise/admin# nslookup 192.168.1.20 Trying "20.1.168.192.in-addr.arpa" ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56529 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;20.1.168.192.in-addr.arpa. IN PTR ;; ANSWER SECTION: 20.1.168.192.in-addr.arpa. 1200 IN PTR ciscodc.cisco.com
Windows Server 2012
Launch a command prompt, and make sure you can perform an 'nslookup' on the hostname/FQDN of the FTD
Verify Windows Server 2012 signs certificates as SHA256 or higher. Double-click your Root CA certificate in Windows and check the 'Signature algorithm' fields
If they are SHA1, most browsers will show a browser warning for those certificates. To change it, you can check here:
How to Upgrade Windows Server Certification Authority to SHA256
Verify the FTD VPN Server Certificate has the following fields correct (when you connect in browser to FTD)
Common Name = <FTDFQDN>
Subject Alternative Name (SAN) = <FTDFQDN>
Example:
Common Name: ciscofp3.cisco.com
Subject Alternative Name (SAN): DNS Name=cicscofp3.cisco.com
Verify using captures on FTD CLI and captures on employee PC using Wireshark to verify that packets are coming over TCP+UDP 443 to the Outside IP of the FTD. Verify that those packets are sourced from the employee's home router's public IP address
