Configuring Virtual Private Networks

Note The VPN menu and its options are not available in the U.S. export unrestricted version of Cisco Unified Communications Manager.

The Cisco VPN Client for Cisco Unified IP Phones adds another option for customers attempting to solve the remote telecommuter problem by complementing other Cisco remote telecommuting offerings.

•Easy to Deploy—All settings configured via CUCM administration.

•Easy to Use—After configuring the phone within the Enterprise, the user can take it home and plug it into their broadband router for instant connectivity, without any difficult menus to configure.

•Easy to Manage—Phone can receive firmware updates and configuration changes remotely.

•Secure—VPN tunnel only applies to voice and Cisco Unified IP Phone services. A PC connected to the PC port is responsible for authenticating and establishing it own tunnel with VPN client software.

Supported Devices

You can use Cisco Unified Reporting to determine which Cisco Unified IP Phones support the VPN client. From Cisco Unified Reporting, click Unified CM Phone Feature List. For the Feature, choose Virtual Private Network Client from the pull-down menu. The system displays a list of products that support the feature.

For more information about using Cisco Unified Reporting, see the Cisco Unified Reporting Administration Guide.

Configuring the VPN Feature

To configure the VPN feature for supported Cisco Unified IP Phones, follow the steps in the following table.

Table 4-1 VPN Configuration Checklist

Configuration Steps
Notes and Related Procedures

Step 1 

Set up the VPN concentrators for each VPN Gateway.

For configuration information, refer to the documentation for the VPN concentrator; such the following:

•SSL VPN Client (SVC) on ASA with ASDM Configuration Example

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a008071c428.shtml

Note The ASA software must be version 8.0.4 or later, and the "AnyConnect Cisco VPN Phone" license must be installed.

Note To avoid long delays when the user upgrades the firmware or configuration information on a remote phone, Cisco recommends that you set up the VPN concentrator close in the network to the TFTP or Cisco Unified Communications Manager server. If this is not feasible in your network, you can set up an alternate TPTP or load server that is next to the VPN concentrator.

•SSL VPN Client (WebVPN) on IOS with SDM Configuration Example

http://www.cisco.com/en/US/products/ps6496/products_configuration_example09186a008072aa61.shtml

Note The IOS software must be versions 15.1(2)T or later. Feature Set/License:" Universal (Data & Security & UC)" for the 2900 models and "Advanced Security" for the 2800 models with SSL VPN licenses activated.

Note To avoid long delays when the user upgrades the firmware or configuration information on a remote phone, Cisco recommends that you set up the VPN concentrator close in the network to the TFTP or Cisco Unified Communications Manager server. If this is not feasible in your network, you can set up an alternate TPTP or load server that is next to the VPN concentrator.

Step 2 

Upload the VPN concentrator certificates.

Chapter 6 "Configuring a VPN Group"

Step 5 

Configure the VPN Profile

Chapter 7 "Configuring a VPN Profile"

Step 6 

Add the VPN Group and VPN Profile to a Common Phone Profile.

In Cisco Unified Communications Manager Administration, choose Device > Device Settings > Common Phone Profile. For more information, see the "Common Phone Profile Configuration" chapter in the Cisco Unified Communications Manager Administration Guide.

Note If you do not associate a VPN Profile with the Common Phone Profile, VPN uses the default settings defined in the VPN Feature Configuration window.

Step 7 

Upgrade the firmware for Cisco Unified IP Phones to a version that supports VPN.

To run the Cisco VPN client, a supported Cisco Unified IP Phone must be running firmware release 9.0(2) or higher. For more information about upgrading firmware, see the Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager for your Cisco Unified IP Phone model.

Note Before you can upgrade to firmware release 9.0(2), supported Cisco Unified IP Phones must be running firmware release 8.4(4) or later.

Step 8 

Using a supported Cisco Unified IP Phone, establish a VPN connection.

For more information about configuring a Cisco Unified IP Phone and establishing a VPN connection, see the Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager for your Cisco Unified IP Phone model.


IOS configuration requirements

Before you create an ISO configuration for VPN client on IP phone, complete the following steps:

Step 1 Install IOS Software version 15.1(2)T or later

Feature Set/License: Universal (Data & Security & UC) for IOS ISR-G2

Feature Set/License: Advanced Security for IOS ISR

Step 2 Activate the SSL VPN License

Configuring IOS for VPN client on IP phone

Perform the following steps to configure IOS for VPN client on IP phone.

Step 1 Configure IOS locally.

a. Configure the Network Interface

Example: 

router(config)# interface GigabitEthernet0/0

router(config-if)# description "outside interface"

router(config-if)# ip address 10.1.1.1 255.255.255.0 

router(config-if)# duplex auto

router(config-if)# speed auto

router(config-if)# no shutdown

router#show ip interface brief (shows interfaces summary)

b. Configure static and default routes.

router(config)# ip route <dest_ip> < mask> < gateway_ip>

Example: 

router(config)# ip route 10.10.10.0 255.255.255.0 192.168.1.1

Step 2 Generate and register the necessary certificates for Cisco Unified Communications Manager and IOS.

The following certificates need to be imported from the Cisco Unified Communications Manager.

•CallManager - Authenticating the Cisco UCM during TLS handshake (Only required for mixed-mode clusters)

•Cisco_Manufacturing_CA - Authenticating IP phones with a Manufacturer Installed Certificate (MIC).

•CAPF - Authenticating IP phones with an LSC.

To import these Cisco Unified Communications Manager certificates

a. From the Cisco Unified Communications Manager OS Administration web page.

b. Choose Security > Certificate Management. (Note: This location may change based on the UCM version)

c. Find the certificates Cisco_Manufacturing_CA and CAPF. Download the .pem file and save as .txt file

d. Create trustpoint on the IOS

Example: 

hostname(config)# crypto pki trustpoint trustpoint_name 

hostname(config-ca-trustpoint)# enrollment terminal

hostname(config)# crypto pki authenticate trustpoint

When prompted for base 64 encoded CA Certificate, copy-paste the text in the downloaded  .pem file along with the BEGIN and END lines. Repeat the procedure for the other certificates

e. You should generate the following IOS self-signed certificates and register them with Cisco Unified Communications Manager, or replace with a certificate that you import from a CA.

•Generate a self-signed certificate.

Example: 

Router> enable

Router# configure terminal

Router(config)# crypto key generate rsa general-keys label <name> <exportable 
-optional>

Router(config)# crypto pki trustpoint <name>

Router(ca-trustpoint)# enrollment selfsigned

Router(ca-trustpoint)# rsakeypair <name> 1024 1024 

Router(ca-trustpoint)#authorization username subjectname commonname

Router(ca-trustpoint)# crypto pki enroll <name>

Router(ca-trustpoint)# end

•Generate a self-signed certificate with Host-id check enabled on the VPN profile in Cisco Unified Communications Manager.

Example: 

Router> enable

Router# configure terminal

Router(config)# crypto key generate rsa general-keys label <name> <exportable 
-optional>

Router(config)# crypto pki trustpoint <name>

Router(ca-trustpoint)# enrollment selfsigned

Router(config-ca-trustpoint)# fqdn <full domain name>

Router(config-ca-trustpoint)# subject-name CN=<full domain name>, CN=<IP>

Router(ca-trustpoint)#authorization username subjectname commonname

Router(ca-trustpoint)# crypto pki enroll <name>

Router(ca-trustpoint)# end

•Register the generated certificate with Cisco Unified Communications Manager.

Example: 

Router(config)# crypto pki export <name> pem terminal

Copy the text from the terminal and save it as a .pem file and upload it to the Managing Certificate part of the CUCM.

Step 3 Install Anyconnect on IOS.

Download anyconnect package from cisco.com and install to flash

Example: 

router(config)#webvpn install svc flash:/webvpn/anyconnect-win-2.3.2016-k9.pkg

Step 4 Configure the VPN feature. You can use the Sample IOS configuration summary bellow to guide you with the configuration.

Note To use the phone with both certificate and password authentication, create a user with the phone MAC address. Username matching is case sensitive. For example:
username CP-7975G-SEP001AE2BC16CB password k1kLGQIoxyCO4ti9 encrypted

ASA configuration requirements

Before you create an ASA configuration for VPN client on IP phone, complete the following steps:

Step 1 Install ASA software (version 8.0.4 or later) and compatible ASDM

Step 2 Install a compatible anyconnect package

Step 3 Activate License

a. Show features of the current license.
show activation-key detail

b. For a new license with additional SSL VPN sessions and Linksys phone enabled, visit http://www.cisco.com/go/license. Select "Any Connect Cisco VPN phone" license to support the VPN feature.

Configuring ASA for VPN client on IP phone

Perform the following steps to configure ASA for VPN client on IP phone.

Step 1 Local configuration

a. Configure network interface.

Example: 

router(config)# interface GigabitEthernet0/0

router(config-if)# description "outside interface"

router(config-if)# ip address 10.1.1.1 255.255.255.0 

router(config-if)# duplex auto

router(config-if)# speed auto

router(config-if)# no shutdown

router#show ip interface brief (shows interfaces summary)

b. Configure static routes and default routes.

router(config)# ip route <dest_ip> <mask> <gateway_ip>

Example: 

router(config)# ip route 10.10.10.0 255.255.255.0 192.168.1.1

c. Configure the DNS.

Example: 

hostname(config)# dns domain-lookup inside

hostname(config)# dns server-group DefaultDNS

hostname(config-dns-server-group)# name-server 10.1.1.5 192.168.1.67 209.165.201.6

Step 2 Generate and register the necessary certificates for Cisco Unified Communications Manager and IOS.

The following certificates need to be imported from the Cisco Unified Communications Manager.

•CallManager - Authenticating the Cisco UCM during TLS handshake (Only required for mixed-mode clusters)

•Cisco_Manufacturing_CA - Authenticating IP phones with a Manufacturer Installed Certificate (MIC).

•CAPF - Authenticating IP phones with an LSC.

To import these Cisco Unified Communications Manager certificates

a. From the Cisco Unified Communications Manager OS Administration web page.

b. Choose Security > Certificate Management. (Note: This location may change based on the UCM version)

c. Find the certificates Cisco_Manufacturing_CA and CAPF. Download the .pem file and save as .txt file

d. Create trustpoint on the IOS

Example: 

hostname(config)# crypto pki trustpoint trustpoint_name 

hostname(config-ca-trustpoint)# enrollment terminal

hostname(config)# crypto pki authenticate trustpoint

When prompted for base 64 encoded CA Certificate, copy-paste the text in the downloaded  .pem file along with the BEGIN and END lines. Repeat the procedure for the other certificates

e. You should generate the following IOS self-signed certificates and register them with Cisco Unified Communications Manager, or replace with a certificate that you import from a CA.

•Generate a self-signed certificate.

Example: 

Router> enable

Router# configure terminal

Router(config)# crypto key generate rsa general-keys label <name> <exportable 
-optional>

Router(config)# crypto pki trustpoint <name>

Router(ca-trustpoint)# enrollment selfsigned

Router(ca-trustpoint)# rsakeypair <name> 1024 1024 

Router(ca-trustpoint)#authorization username subjectname commonname

Router(ca-trustpoint)# crypto pki enroll <name>

Router(ca-trustpoint)# end

•Generate a self-signed certificate with Host-id check enabled on the VPN profile in Cisco Unified Communications Manager.

Example: 

Router> enable

Router# configure terminal

Router(config)# crypto key generate rsa general-keys label <name> <exportable 
-optional>

Router(config)# crypto pki trustpoint <name>

Router(ca-trustpoint)# enrollment selfsigned

Router(config-ca-trustpoint)# fqdn <full domain name>

Router(config-ca-trustpoint)# subject-name CN=<full domain name>, CN=<IP>

Router(ca-trustpoint)#authorization username subjectname commonname

Router(ca-trustpoint)# crypto pki enroll <name>

Router(ca-trustpoint)# end

•Register the generated certificate with Cisco Unified Communications Manager.

Example: 

Router(config)# crypto pki export <name> pem terminal

Copy the text from the terminal and save it as a .pem file and upload it to the Managing Certificate part of the CUCM.

Step 3 Configure the VPN feature. You can use the Sample IOS configuration summary bellow to guide you with the configuration.

Note To use the phone with both certificate and password authentication, create a user with the phone MAC address. Username matching is case sensitive. For example:
username CP-7975G-SEP001AE2BC16CB password k1kLGQIoxyCO4ti9 encrypted
username CP-7975G-SEP001AE2BC16CB attributes vpn-group-policy GroupPhoneWebvpn service-type remote-access
