License Options

For the most updated information on AnyConnect licensing on the RV340 series routers, check out the article AnyConnect Licensing for the RV340 Series Routers.

4. What are the licenses that may be required for the deployment of AnyConnect Secure Mobility Client?

One or more of the following AnyConnect licenses may be required for your deployment:

- AnyConnect Plus — Supports basic AnyConnect features such as VPN functionality for PC and mobile platforms (AnyConnect and standards-based IPsec Internet Key Exchange version 2 (IKEv2) software clients), Federal Information Processing Standard (FIPS), basic endpoint context collection, 802.1x Windows supplicant, and web security Secure Sockets Layer (SSL) VPN. Plus licenses are most applicable to environments previously served by the AnyConnect Essentials license and users of Cisco Identity Services Engine (ISE) posture, Network Access Manager, or Web Security modules.

- AnyConnect Apex — Supports all basic AnyConnect Plus features in addition to advanced features such as clientless VPN, VPN posture agent, unified posture agent, Next Generation Encryption or Suite B, Security Assertion Markup Language (SAML), all plus services and flex licenses. Apex licenses are most applicable to environments previously served by the AnyConnect Premium, Shared, Flex, and Advanced Endpoint Assessment licenses.

- VPN Only (Perpetual) — Supports VPN functionality for PC and mobile platforms, clientless (browser-based) VPN termination on Adaptive Security Appliance (ASA), VPN-only compliance and posture agent in conjunction with ASA, FIPS compliance, and next-generation encryption (Suite B) with AnyConnect and third-party IKEv2 VPN clients. VPN only licenses are most applicable to environments wanting to use AnyConnect exclusively for remote access VPN services but with high or unpredictable total user counts. No other AnyConnect function or service (such as Web Security module, Cisco Umbrella Roaming, ISE Posture, Network Visibility module, or Network Access Manager) is available with this licensee.

Installation

12. Is AnyConnect weblaunch installation supported on 64-bit browsers (IE - Internet Explorer)?

AnyConnect installation via weblaunch is not supported on 64-bit IE browsers.

13. What level of rights is required to install the Cisco AnyConnect Secure Mobility Client?

Administrative level privilege is required to install the Cisco AnyConnect Secure Mobility Client but only for initial installation.

15. Is it possible to save the password credentials on AnyConnect so that it will not request authentication again the next time?

No, it is not possible to save the password credentials on AnyConnect.

Compatibility

16. What Interoperability Considerations should I keep in mind before installing the Cisco AnyConnect Secure Mobility?

- Coexistence of ISE and ASA Headends

- If you are using both ISE and ASA for client posture, the profiles must match on both headends.

- AnyConnect ignores the ISE 1.3 server if Network Access Control (NAC) Agent is provisioned for the endpoint.

- If the Cisco NAC agent and the VPN Posture (HostScan) module are both installed on a client, the Cisco NAC agent must be at least version 4.9.4.3 or later to prevent posture conflicts.

- The NAC Agent ignores the ISE 1.3 server if AnyConnect is provisioned for the endpoint in ISE.

17. What are the known third party applications that conflict with the Cisco AnyConnect Secure Mobility?

The following third-party applications have known complications with Cisco AnyConnect Secure Mobility Client:

- Adobe and Apple — Bonjour Printing Service

- Adobe Creative Suite 3

- Bonjour Printing Service

- iTunes

- AT&T Communications Manager Versions 6.2 and 6.7

- AT&T Sierra Wireless 875 card

- AT&T Global Dialer

- Citrix Advanced Gateway Client Version 2.2.1

- Firewall Conflicts

- Third-party firewalls can interfere with the firewall function configured on the ASA group policy.

- Juniper Odyssey Client

- Kaspersky AV Workstation 6.x

- McAfee Firewall 5

- Microsoft Internet Explorer 8

- Microsoft Routing and Remote Access Server

- Microsoft Windows Update

- OpenVPN client

- Load balancers

- Wave EMBASSY Trust Suite

- Layered Service Provider (LSP) Modules and NOD32 AV

- EVDO Wireless Cards and Venturi Driver

- DSL routers

- CheckPoint and other Third-Party Software such as Kaspersky

- Virtual Machine Network Service Drivers

- The Windows firewall can block packets from the remote site. If you disable the firewall, you should be able to access those folders.

18. Can AnyConnect co-exist with IPSec and/ or SSL VPN clients from other vendors on the same PC?

Yes. But the following general rules apply to all AnyConnect versions:

The AnyConnect client should work fine if the other vendor products are disabled and the following should NOT be done:

- Install a Winsock LSP that remains active when the 3rd party software is not running.

- Install a local http proxy that remains active when the 3rd party software is not running.

- Installs any drivers that continue to intercept traffic when the 3rd party software is not running.

- Additionally, any restrictions that are done to the MTU of the physical interface could result in performance degradation.

Basic Troubleshooting

19. When AnyConnect attempts to establish a connection, it authenticates successfully and builds the SSL session, but then the AnyConnect client crashes in the vpndownloader if using LSP or NOD32 AV. What should I do?

Remove the Internet Monitor component in version 2.7 and upgrade to version 3.0 of ESET NOD32 AV.

20. I am using an AT&T Dialer and the client operating system sometimes experiences a blue screen that causes the creation of a mini dump file. What should I do?

Upgrade to the latest 7.6.2 AT&T Global Network Client.

21. When Kaspersky 6.0.3 is installed (even if disabled), AnyConnect connections to the ASA fail right after CSTP state = CONNECTED and the following message appears: “SVC message: t/s=3/16: Failed to fully establish a connection to the secure gateway (proxy authentication, handshake, bad cert, etc.).”

Uninstall Kaspersky and refer to their forums for additional updates.

22. When using McAfee Firewall 5, a UDP DTLS connection cannot be established.

In the McAfee Firewall central console, choose Advanced Tasks > Advanced options and Logging and uncheck the Block incoming fragments automatically check box in McAfee Firewall.

23. I am using RRAS, the following termination error is returned to the event log when AnyConnect attempts to establish a connection to the host device: “Termination reason code 29 [Routing and Remote Access service is running] The Windows service “Routing and Remote Access” is incompatible with the Cisco AnyConnect VPN Client. “

Disable the RRAS service.

24. What should I do if the connection fails due to lack of credentials?

The third-party load balancer has no insight into the load on the ASA devices. Because the load balance functionality in the ASA is intelligent enough to evenly distribute the VPN load across the devices, we recommend using the internal ASA load balancing instead.

25. The AnyConnect client fails to download and produces the following error message: “Cisco AnyConnect VPN Client Downloader has encountered a problem and needs to close.”

Upload the patch update to version 1.2.1.38 to resolve all dll issues.

26. I am using Bonjour Printing Services, the AnyConnect event logs indicate a failure to identify the IP forwarding table.

Disable the Bonjour Printing Service by entering net stop “bonjour service” at the command prompt. A new version of mDNSResponder (1.0.5.11) has been produced by Apple. To resolve this issue, a new version of Bonjour is bundled with iTunes and made available as a separate download from the Apple web site.

27. An error indicates that the version of TUN is already installed on this system and is incompatible with the AnyConnect client.

Uninstall the Viscosity OpenVPN Client.

28. What should I do if an LSP module is present on the client and a Winsock catalog conflict occurs?

Uninstall the LSP module.

29. I am connecting with a DSL router, and DTLS traffic fails even if it has successfully negotiated. What should I do?

Connect to a Linksys router with factory settings. This setting allows a stable DTLS session and no interruption in pings. Add a rule to allow DTLS return traffic.

30. When using AnyConnect on some Virtual Machine Network Service devices, performance issues have resulted. What should I do?

Uncheck the binding for all IM devices within the AnyConnect virtual adapter. The application dsagent.exe resides in C:\Windows\System\dgagent. Although it does not appear in the process list, you can see it by opening sockets with TCPview (sysinternals). When you terminate this process, normal operation of AnyConnect returns.
