Cisco AnyConnect::How to hide "security warning: Untrusted certificates.

Whenever I connect to my ASA using the client Anyconnect, attached warning message still appears and there is no option to trust him or import the certificate so that it should not appear the next time.

Someone please help to make the visible option to trust certificate or to make the warning go away.

I tried Anyconnect 3.1.05152 and later also.

The best way is to buy a certificate for your ASA and install it there.

If you cannot or do not want to do this, you create a self-signed certificate well trained on the SAA. You must make sure your have a 2048-bit RSA right key (or create a new one, when you start).

If you use a fully qualified domain (FQDN) for the VPN user name to access the ASA which should be the common name (CN) in the certificate. Which addresses the point #1 in the warning.

Your customers will need to download and install the certificate in their store of trusted CA root. You can do this by browsing the web portal and using your browser tools to copy the ASA SSL certificate to a local file and then import, the substitution of the default location and choosing the store of authority CA root of trust. This element addresses #2.

Point #3 is also because of the way the self-signed certificate has been created. If you follow the configuration guide, you must have a correct certificate and not get this error.

  • Cisco AnyConnect secure mobility Client - totally lost Newbie

    We currently have an ASA 5505 Firewall VPN configured services.  The system runs ASA Version 9.0.0 and ADSDM 7.0.2.  I installed the 'Cisco AnyConnect none mobility Client' Version 3.1.01065 on my PC to Windows 7 Ultimate.  When I try to connect to my VPN service I ge the following message is displayed:

    Security Warning: no reliable VPN server certificate!  AnyConnect cannot check the VPN server: XXX.XXX. XX. XX

    Certifiate does not match the name of the server

    Certificate comes from an untrusted source.

    Certificate is not identified for this purpose.

    Without buying a certificate from a 3rd party provider, is it possible to record a 'self' generated by certificate to get rid of this message?  If so, are there any "detailed" (e.g., simplified or not in the language of Cisco-eeze) instructions on how to configure the firewall to 'push' the certificate to the VPN client, so the message doesn't look for the user?

    I can have wrongly assumed your never worked WHAT VPN remote access.

    By comparing your error message with that I get when I tell my client to block connections to untrusted servers shows I get a unique, different warning screen (below). I suspect you may have more than just the question aside customer. You can share your configuration?

  • Cisco AnyConnect Secure mobility Client cannot initialize connection subsystem after updates Windows (Feb 10, 2015)

    Hello

    The customer Cisco Anyconnect Secure mobility gives me an error when I try to use it. It started after the latest updates for Windows (10 Feb. 2015).

    The error it causes is "could not initialize the subsystem of connection".

    I looked at another machine with the updates installed with same issue.

    On my machine - I back before restore point windows updates be done, and the Cisco Anyconnect Client's worked well.

    After you install the updates, it stopped working again.

    Help, please

    Michael

    I assume you are using Windows 8.1. The workaround is to set the AnyConnect Client to use Windows 8 Compatibility Mode. He has worked on several machines. After the change, you will need to log off the coast and turn it on for Windows.

    Cumulative update 11 IE KB3021952 includes KB3023607.  Apparently, it's the latest patch that causes the problem, according to what I said. (I do not even 3023607 in the history of WU, but if I type "wmic qfe" is here). However, I suggest updating leaving in place and using workaround.

  • Configuration Cisco AnyConnect secure mobility assistance

    Hello!

    A partner of CIsco of Singapore asks if it would be possible on Cisco Anyconnect Secure Mobility

    If I want to use "Cisco AnyConnect Secure mobility" in Anyconnect 3.0, I can set that the user is not able to access all traffic via a wireless sound card when the VPN is established via the wired LAN port. I want to prevent any bypass between these two network ports if the VPN in place.

    In addition, to enable split tunneling so that all traffic has to go through the VPN tunnel?

    Kind regards!

    Ice Flancia

    Cisco partner Helpline Tier 2 team

    To route all traffic to the VPN tunnel, split tunnel should be turned off (not enabled).

    Under group policy configuration: split-tunnel-policy tunnelall

    Once the split tunnel is disabled, VPN users will not be able to access one of its local LAN networks (including wireless).

    Hope that helps.

    Update: checked eventviewer on laptop. same errors as above from there. Establish VPN, however.

    Hi RRoman_404,

    I suggest you perform the clean boot and check.

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

    If this doesn't help, you may need to contact the vendor of the application.

    It will be useful.

    My question is how still works activated when connecting to wifi networks where you can drop in their net comments to authenticate on a Web page?

    Could deduct the initial communication and then kick VPN requirements?

    Hey, Derrick.

    This portal of comments is usually called "Captive portal", and Cisco AnyConnect has an option to detect captive portals. For more information, see:
