See full list on cisco.com. I'm using the Cisco VPN Client 5.0.02.0090 to connect to my work's VPN that way I can RDP into my work computer. Once connected, I can't ping anything on the local network once connected to the VPN thus I am unable to access my work's network. This used to work about two weeks ago but abruptly stopped working today. Cisco AnyConnect used to work on my laptop. Now when it starts, the dialog pops up for a moment, but the VPN location dropdown and Connect button are disabled. Then the dialog goes away and no connection is made. Internal support said my profile is probably the problem and that I should re-image the machine, which is not a viable option. Hi, Its been a while since I first wrote the article. I’m currently using Windows 10 Pro, 64-bit on a Microsoft Surface Pro 3. The version of the Cisco AnyConnect Secure Mobility Client is 3.1.12020. Cisco AnyConnect VPN client is widely used by corporates. Now everyone are working from home and rely on VPN for connecting to corporate network. Relating to VPN not working in windows 10 and other Most common problems are reporting to IT helpdesk are.

I was trying to log into work but had trouble making a VPN connection. I use Cisco AnyConnect VPN Client. This post describes how to fix the following error messages when using Windows 8 Pro:

• AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.

• The VPN client driver encountered an error. Please restart your computer or device, then try again.

The steps to fix this problem are as follows:

1. Edit a registry entry by running a program called regedit. Right-click on it and Run as administrator. Note that I use Start8, by Stardock, to have a Start button and menu. After you left-click on Run as administrator, your computer might ask you to enter the admin password.

2. Go to the appropriate VPN registry directory called ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesvpnva

3. Double left-click the DisplayName key.

An Edit String pop-up window will appear.

The text under the Value data: field on my computer looked like this.

@oem20.inf,%vpnva_Desc%;Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

4. Change the field to

Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

by removing all the text and characters that are on the left of the word Cisco.

The end result should look like this:

5. Left-click the ‘OK’ button.

6. Exit the Registry Editor

7. Run Cisco AnyConnect VPN Client and reconnect.

That’s all there is to it. Good luck!

Update : 2/13/2014

I recently updated my computer on February 13, 2014 with Microsoft’s updates and saw that the text under the Value data: field on my computer looked like this:

@oem10.inf,%VPNVA64_Desc%;Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

It is different from what I had originally posted. I’m not really sure how or why it changed and I don’t have time to find out. I also updated to Cisco AnyConnect Secury Mobility Client Version 3.1.04066. As far as I can tell, the value of …

@oem10.inf,%VPNVA64_Desc%;Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

.. works, but the value of

Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

does not work with Cisco AnyConnect Secury Mobility Client Version 3.1.04066.

Update : 2/15/2014

Changing the Value data: field to

Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

without

@oem10.inf,%VPNVA64_Desc%;

seems to work better, too.

Introduction

This document describes how to troubleshoot some of the most common communication issues of the Cisco AnyConnect Secure Mobility Client on Firepower Threat Defense (FTD) when it uses either Secure Socket Layer (SSL) or Internet Key Exchange version 2 (IKEv2).

Contributed by Angel Ortiz and Fernando Jimenez, Cisco TAC Engineers.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• Cisco AnyConnect Secure Mobility Client.
• Cisco FTD.
• Cisco Firepower Management Center (FMC).

Components Used

The information in this document is based on these software and hardware versions:

• FTD managed by FMC 6.4.0.
• AnyConnect 4.8.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Recommended troubleshoot process

This guide explains how to troubleshoot some common communication issues that AnyConnect clients have when the FTD is used as Remote Access Virtual Private Network (VPN) gateway. These sections address and provide solutions to problems below:

• AnyConnect clients cannot access internal resources.
• AnyConnect clients do not have internet access.
• AnyConnect clients cannot communicate between each other.
• AnyConnect clients cannot establish phone calls.
• AnyConnect clients can establish phone calls. However, there is no audio on the calls.

AnyConnect clients cannot access internal resources

Complete these steps:

Step 1. Verify Split tunnel configuration.

• Navigate to the Connection Profile that AnyConnect clients are connected to: Devices > VPN > Remote Access > Connection Profile > Select the Profile.
• Navigate to the Group-Policy assigned to that Profile: Edit Group Policy > General.
• Check the Split Tunneling configuration, as shown in the image.
  

• If it's configured as Tunnel networks specified below, verify the Access Control List (ACL) configuration:

Navigate to Objects > Object Management > Access List > Edit the Access List for Split tunneling.

• Ensure that the networks that you try to reach from the AnyConnect VPN client are listed in that Access List, as shown in the image.
  

Step 2.Verify Network Address Translation (NAT) exemption configuration.

Remember that we must configure a NAT exemption rule to avoid traffic to be translated to the interface IP address, usually configured for internet access (with Port Address Translation (PAT)).

• Navigate to the NAT configuration: Devices > NAT.
• Ensure that the NAT exemption rule is configured for the correct source (internal) and destination (AnyConnect VPN Pool) networks. Also check that the correct source and destination interfaces have been selected, as shown in the image.

Note: When NAT exemption rules are configured, check the no-proxy-arp and perform route-lookup options as a best practice.

Step 3. Verify Access Control Policy.

Per your Access Control Policy configuration, ensure that traffic from the AnyConnect clients is allowed to reach the selected internal networks, as shown in the image.

AnyConnect clients do not have internet access

There are two possible scenarios for this issue.

1. Traffic destined for the internet must not go through the VPN tunnel.

Ensure that the Group-Policy is configured for Split tunneling as Tunnel networks specifiedbelow and NOT as Allow all traffic over tunnel, as shown in the image.

2. Traffic destined for the Internet must go through the VPN tunnel.

In this case, the most common Group-Policy configuration for Split tunneling would be to select Allow all traffic over tunnel, as shown in the image.

Step 1. Verify NAT exemption configuration for internal network reachability.

Remember that we must still configure a NAT exemption rule to have access to the internal network. Please review Step 2 of the AnyConnect clients cannot access internal resource section.

Step 2. Verify hairpinning configuration for dynamic translations.

In order for AnyConnect clients to have internet access through the VPN tunnel, we need to ensure that the hairpinning NAT configuration is correct for traffic to be translated to the interface´s IP address.

• Navigate to the NAT configuration: Devices > NAT.
• Ensure that the Dynamic NAT rule is configured for the correct interface (Internet Service Provider (ISP) link) as source and destination (hairpinning). Also check that the network used for the AnyConnect VPN address pool is selected in Original source and the Destination Interface IP option is selected for Translated source, as shown in the image.
  

Step 3. Verify Access Control Policy.

Per your Access Control Policy configuration, ensure that traffic from the AnyConnect clients is allowed to reach the external resources, as shown in the image.

AnyConnect clients cannot communicate between each other

There are two possible scenarios for this issue:

1. AnyConnect clients with Allow all traffic over tunnel configuration in place.
2. AnyConnect clients with Tunnel networks specified below configuration in place.

1. AnyConnect clients with Allow all traffic over tunnel configuration in place.

When Allow all traffic over tunnel is configured for AnyConnect means that all traffic, internal and external, should be forwarded to the AnyConnect headend, this becomes a problem when you have NAT for Public Internet access, since traffic comes from an AnyConnect client destined to another AnyConnect client is translated to the interface IP address and therefore communication fails.

Step 1. Verify NAT exemption configuration.

In order to overcome this problem a manual NAT exemption rule must be configured to allow bidirectional communication within the AnyConnect clients.

• Navigate to the NAT configuration: Devices > NAT.
• Ensure that the NAT exemption rule is configured for the correct source (AnyConnect VPN Pool) and destination. (AnyConnect VPN Pool) networks. Also check that the correct hairpin configuration is in place, as shown in the image.
  

Step 2. Verify Access Control Policy.

Per your Access Control Policy configuration, ensure that traffic from the AnyConnect Clients is allowed, as shown in the image.

2. Anyconnect clients with Tunnel networks specified below configuration in place.

With Tunnel networks specified below configured for the AnyConnect clients only specific traffic is forwarded to through the VPN tunnel. However, we need to ensure that the headend has the proper configuration to allow communication within the AnyConnect clients.

Step 1. Verify NAT exemption configuration.

Please check Step 1, in the Allow all traffic over tunnel section.

Step 2. Verify Split tunneling configuration.

For AnyConnect clients to communicate between them we need to add the VPN pool addresses into the Split-Tunnel ACL.

• Please follow Step 1 of the AnyConnect clients cannot access internal resources section.
• Ensure that the AnyConnect VPN Pool network is listed in the Split tunneling Access List, as shown in the image.
  

Note: If there is more than one IP Pool for AnyConnect clients and communication between the different pools is needed, ensure to add all of the pools in the split tunneling ACL, also add a NAT exemption rule for the needed IP Pools.

Step 3. Verify Access Control Policy.

Ensure that traffic from the AnyConnect clients is allowed as shown in the image.

AnyConnect clients cannot establish phone calls

There are some scenarios where AnyConnect clients need to establish phone calls and video conferences over VPN.

AnyConnect clients can connect to the AnyConnect headend without any problem. They can reach internal and external resources, however phone calls cannot be established.

For this cases we need to consider the follow points:

• Network topology for voice.
• Protocols involved. I.e. Session Initiation Protocol (SIP), Rapid Spanning Tree Protocol (RSTP), etc.
• How the VPN phones connect to the Cisco Unified Communications Manager (CUCM).

By default, FTD and ASA have applications inspection enabled by default in their global policy-map.

In most cases scenarios the VPN phones are not able to establish a reliable communication with the CUCM because the AnyConnect headend has an application inspection enabled that modifies the signal and voice traffic.

For more information about the voice and video application where you can apply application inspection see the follow document:

In order to confirm if an application traffic is dropped or modified by the global policy-map we can use the show service-policy command as shown below.

In this case we can see how SIP inspection drops the traffic.

Moreover, SIP inspection can also translate IP addresses inside the payload, not in the IP header, causes different issues, hence it is recommended to disable it when we want to use voice services over AnyConnect VPN.

In order to disable it we need to complete the next steps:

Step 1. Enter the privileged EXEC mode.

For more information on how to access this mode see the next document:

Step 2. Verify the global policy-map.

Run the next command and verify if SIP inspection is enabled.

Step 3. Disable SIP inspection.

If SIP inspection is enabled, turn it off running command below from clish prompt:

Step 4. Verify the Global Policy-map again.

Ensure that SIP inspection is disabled from the global policy-map:

AnyConnect clients can establish phone calls, however there is no audio on the calls

As mentioned in the previous section, a very common need for AnyConnect clients is to establish phone calls when connected to the VPN. In some cases the call can be established, however clients may experience lack of audio on it. This applies to the next scenarios:

• No audio on the call between an AnyConnect client and an external number.
• No audio on the call between an AnyConnect client and another AnyConnect client.

In order to get this fixed, we can follow these steps:

Step 1. Verify Split tunneling configuration.

Cisco Anyconnect Mobility VPN Client Will Not Connect With ...

• Navigate to the Connection Profile use to connect to: Devices > VPN > Remote Access > Connection Profile > Select the Profile.
• Navigate to the Group-Policy assigned to that Profile: Edit Group Policy > General.
• Check the Split Tunneling configuration, as shown in the image.

• If configured as Tunnel networks specified below, verify the Access List configuration: Objects > Object Management > Access List > Edit the Access List for Split tunneling.

• Ensure that the Voice Servers and the AnyConnect IP Pool networks are listed in the Split tunneling Access List, as shown in the image.

Step 2. Verify NAT exemption configuration.

NAT exemption rules must be configured to exempt traffic from the AnyConnect VPN network to the Voice Servers network and also to allow bidirectional communication within the AnyConnect clients.

• Navigate to the NAT configuration: Devices > NAT.

• ensure that the NAT exemption rule is configured for the correct source (Voice Servers) and destination (AnyConnect VPN Pool) networks, and the hairpin NAT rule to allow AnyConnect client to AnyConnect client communication is in place. Moreover, check that the correct inbound and outbound interfaces configuration is in place for each rule, per your network design, as shown in the image.
  

Step 3. Verify that SIP inspection is disabled.

Please review the previous section AnyConnect clients cannot establish phone calls to know how to disable SIP inspection.

Step 4. Verify Access Control Policy.

Per your Access Control Policy configuration, ensure that traffic from the AnyConnect clients is allowed to reach the Voice servers and involved networks, as shown in the image.
