• Certificates for IPSEC vpn in ASA 8.0 clients

  Hello!

  Why the use of the key is invalid? What model of certificate must be used in MS in order to get a regular use of the key?

  Thank you!

  The cert needs to have defined Digital Signature key usage.

  Don't know what models are available on MS, but it should be something like "User Ipsec" I guess.

  Make 8 ASA behave like ASA 7 (i.e. disable th control on the use of the key of the cert), configure:

  Crypto ca trustpoint

• Type of certificate for ASA VPN IPSEC

  Hi all

  I'm looking to set up an IPSec VPN connection that will authenticate users by certificate only. I configured everything successfully with the local AAA login, but seeks to convert a signed certificate and generate certificates user for users that are not part of a company or Active Directory.

  So here's my question. What kind of certificate I buy (lets say VeriSign aka Symantec)? And if I want to only use this certificate for my VPN and its customers, can I install it on the Cisco ASA and generate user certificates, or should I set up a Windows Server with CA and create all the certificates on this machine?

  My goal is to install the agent AnyConnect 3.1.x on laptop computer of the user, install the certificate user myself. No webVPN or on behalf of the user. I tried the local certification authority in the ASA in a dev environment, but have had no luck so I thought I'd just signed good immediately.

  Thanks in advance,

  BROKEN

  > Do you think I should have a 3rd party signed certificate

  If the VPN is not only used for internal staff, and then always opt for a public certificate. If you ask other users to install your root certificate, you ask them to allow you to be a man in the Middle for all their traffic. It's nothing that needs to be done.

  Registration is generally just to configure the trustpoint and install the certificate. It is very likely that the certification authority uses an intermediate certification authority, so you should install that also. (even keep the AC have howtos on various platforms).

  > I'm still learning here so I apologize if my questions seem to be amateur.

  And be assured, learning never stop... :-)

• Is availble for IPsec VPN FOS 6.3 support stateful failover

  Is availble for IPsec VPN FOS 6.3 support stateful failover

  SAJ

  Hello Saj,

  Unfortunately not... stateful failover replica information such as:

  Table of connection TCP, udp xlate table ports, h.323, PAT port allocation table...

  they replicate data such as:

  user authentication (uauth) table

  Table ISAKMP / IPSEC SA

  ARP table

  Routing information

  Therefore, in the case where the main breaks down, the IPSEC vpn will be reformed for the failover... Meanwhile, the user will not be able to access the applications...

  I hope this helps... all the best... the rate of responses if deemed useful...

• "ITS creation failed" problem for IPSec VPN

  An ASA 5100 is used to provide VPN access for my business. The configuration was made by a permeable man who has been missing for some time, and the configuration used to be OK until this morning. This morning, some users reported that their VPN would have fallen once got connected. I checked the ASA and ASDM, I see every time when user deletes, it IPSec tunnel is always action. Furthermore, I faked the problem and got the newspaper of errors such as:

• How to set up certificates for the default user profile

  I'm trying to create a package to install Firefox in our corporate environment that contains our locally-issued certificates. We can manually import the certs, but since Firefox is part of our brand, I would like to have the certificates already installed for users they open FF for the first time.

  I wrote a script that installs Firefox 22, copy custom files in the correct location files, creates a new profile folder (C:\Program Files (x 86) \Mozilla Firefox\defaults\profile) and copy the file cert8.db in that newly created file. However, when a user opens FF for the first time, none of our certificates are installed. If I close FF, copy the file cert8.db even in the .default file C:\Users\ < username > \AppData\Roaming\Mozilla\Firefox\Profiles\ < random string > and then reopen FF, CERT now show as installed upward.

  How can I automate this so that each user who opens FF will have implemented CERT?

  This is for the initial installation of Firefox.
  22 of Firefox, version 22.0.0.4917
  Windows 7, 64-bit

  Hello keslaa, since firefox 21 & upward this information would need to go to % ProgramFiles(x86) %\Mozilla Firefox\browser\defaults\profile in order to take effect.

• ASA static IP Addressing for IPSec VPN Client

  Hello guys.

  I use a Cisco ASA 5540 with version 8.4.
  I need to assign a static IP address to a VPN client. I saw in the documentation Cisco that this can be done to validate the user against the local ASA and in the user account database, you assign a dedicated IP address, or using the vpn-framed-ip-address CLI command.
  The problem is that the customer never gets this address and it always gets one of the pool in the political group. If I delete this pool, the client can't get any address.
  No idea on how to fix this or how can I give this static IP address to a specific VPN client?
  Thank you.

  Your welcome please check the response as correct and mark.

• ASA - 5540 used for IPSec VPN only - I can do away with Nat 0?

  I'll use an ASA 5540 as our head of VPN endpoint only - and not as a firewall.

  Also, we have a class for our company internal address space routable B address, so we don't need NAT. I would like to disable the function NAT 0 if I can so I always add NAT 0 to ensure that the 5540 does not NAT.

  Y at - it an easy way to disable the need using NAT 0?

  Are there any of the draw to do that?

  You can disable the use of nat 0 disabling the nat control.

  To achieve this, go to the global configuration mode and use this command:

  no nat control

  To check whether you have it turned on, you can check it with:

  SH run nat-control

• Unique remote IP for IPSec VPN router to router

  Hi, I am setting up a virtual private network to another company, and they provided a routable IP address to be peers and their local internal system we need access to.  Can I use the address of the remote peer in the crypto ACL?  I think that they need to provide a second IP NAT for their internal system, if not for their peers IPSec traffic will hit the ACL crypto.  What do you think?  Thank you!

  As long as only 1 end of the peer uses the peer IPSec (destination ip address) in the ACL crypto, it's OK. You can't have two ends as being the ACL crypto.

• Router configuration Cisco for the IPSec VPN with VPN in Windows 7 builtin client

  Where can I find an example config for IPSec VPN where Windows 7 native client to connect to the Cisco routers. I use the cisco 881w, in this case.

  Thomas McLeod

  Native Client Windows supports only L2TP over IPSec. Example at the end of this doc may be enough for you:

  http://www.Cisco.com/en/us/docs/security/vpn_modules/6342/configuration/guide/6342vpn4.html#wp1036111

  I've not personally configured L2TP/IPSec on IOS, only on ASA, so cannot be 100% sure that the config in the link works, but the general idea should be ok.

• ASA5505: Configure the ASA for IPSec and SSL VPN?

  Hello-

  I currently have my 5505 for SSL AnyConnect VPN connections Setup.  Is it possible to set up also the 5505 for IPSec VPN connections?

  So, basically my ASA will be able to perform SSL and IPSec VPN tunnels, at the same time.

  Thank you!

  Kim,

  Yes, you can configure your ASA to support the AnyConnect VPN IPSec connections and at the same time.  In short, for the configuration of IPSec, you should configure at least a strategy ISAKMP, a set of IPSEC, encryption, tunnel group card processing and associated group policy.

• Remote VPN users

  Hello

  I would just ask how many simultaneous remote client VPN users is allowed for a Cisco1841 router? Are there licenses required?

  Also, will there be a degradation of the performance of the router if there as 15 concurrent users active remote client and VPN L2L 2?

  Thank you!

  For IPSEC, I don't think that there are all the necessary licenses. For SSL, they (but it still works without the license, but unethical).
