• It is recommended to have a vulnerability for Cisco ASA device scan.

  Dear everybody.

  I have a doubt about the analysis of vulnerabilities for Cisco ASA device. Currently we have a vulnerability to network devices include firewalls. But after race for cisco ASA vulnerability scanning, found nothing in the analysis report.

  Is it is recommended to have a Cisco ASA vulnerability scanning and it will defeat the purpose of the firewall?

  I do not understand you ask you can set the ASA to allow an external user, run an analysis on the internal network?

  If so the answer is generally no. The ASA, by default, not allow incoming connections (or attempts of connections) that are not explicitly allowed in a list of inbound access (applied to the external interface). In most cases there should also be (NAT) network address translation rules configured.

  If you had a remote access VPN, you can allow external scanner to connect through that, then they would have the necessary access to analyze internal systems (assuming that allowed VPN access to all internal networks)

• Setting up a VPN between a WRVS4400N and ASA device

  I'm a newbie when it comes to Cisco devices and I have a problem setting a VPN between a local and a seat some distance away.

  Here, our local office, we have a device Cisco WRVS4400N Small Business.

  At Headquarters, they have a feature of Cisco ASA.

  We must set up a point to point VPN and I have no idea how to proceed with these devices.

  To compound things, resources, I'm at the other end in an unknown entity that also does not seem to have a lot of experience with this.

  Is there any type of step by step guide for such a configuration?

  If not, can someone please help with this?

  Hello William,.

  I would call 1866-606-1866 Support Center for assistance on the side the tunnel then the entire side of the ASA WRVS has to do is match the settings. If the side ASA needs support with which we can transfer more TAC.

• SE temp cert of Cisco ASA: device selects point trust ASA-self-signature for client

  Hi all

  After that I imported a GlobalSign Certificate from a another ASA anyconnect users receive this error message:

• ASA 5505 - password

  Hello

  I'm new with ASA devices

  I have an ASA 5505, former Director of COMPUTING doesn't remember the password of it. I wonder what I lose the configuration on it if I reset the

  password?

  If so, how do I download the configuration before you reset the password.

  and how can I download the downloaded configuration

  Thanks in advance for your time

  Hello

  The Cisco document should detail the steps for password recovery.

  http://www.Cisco.com/en/us/docs/security/ASA/asa72/configuration/guide/trouble.html#wp1058131

  Basically, what this does is

  • He starts the ASA without configuration
  • When his kick copy you the original to the ASA configuration
  • Since you have already started the ASA and have management access copy the old configuration to start the running configuration will not affect your management connection (in other words you will not be asked to authenticate)
  • In the meantime, you should be able to use the typical show commands to get the configuration copied to Notepad or even send it to tftp server I guess

  There are several guides online or even on Youtube videos that go through the process more clearly than the simple section of the Cisco document I linked above.

  You should not lose your configuration unless you somehow manage to crush

• Political scene discovered on device in MSC

  Hello world

  I've added mutli context mode MSC ASA device.

  I read that if I get political on the device already in network discovery it copy all the current config of the MSC device

  Need to know if it is safe on SAA in production and it won't change anything about ASA config?

  This unit is in mode multicontext.

  It will also copy the configuration from all contexts?

  Concerning

  Mahesh

  No production change will never happen on CSM without a user authorized to perform and confirming their.

  The configurations of all the contexts will be imported if you discover the device via the IP address of the admin context.

• 2 licenses of anyconnect ASA

  Hello

  I know that I asked this question once, but I need to make sure, please help me.

  If I have two ASA-5545-x and I want to buy a license appex for 1000 users, should I order

  licenses of two 1 k, I want to say can I just order a separate license for each of the ASA devices or

  a 1 k license is sufficient.

  Thanks for the reply.

  A single license is enough. Part number L - AC - APX-[1, 3, or 5] year - G with sub-line items specifying the number of licenses.

  Also, with the new model license AnyConnect 4.x, you can exchange the PAKs on several serial numbers ASA as licensing by using network ASA head.

• ASA 5545 and Anyconnect Licenses

  Currently, we use several devices to Cisco ASA 5545.  Initially, we learned that we were automatically allowed using the Anyconnect Secure Mobility client with our ASA devices.   With recent security issues, we are trying to move to a solution that supports TLS 1.2, and it seems that anyconnect Mobility Client 4.0 will do exactly that.   My question is, the automatic authorization supplied with the unit of 5545 ASA include Client Anyconnect 4.0?   After an exhaustive search, I am still unable to find this information.   Also, is there an official document detailing exactly what licenses is part of 5545 device, with respect to other Cisco Software Solutions?

  Thank you

  David

  All * ASAs include two licenses AnyConnect Premium "free." Which is designed primarily for the evaluation, as most businesses need more two simultaneous remote access users. However, if that's all you need is free and fully functional. It was designed around the Client AnyConnect Secure Mobility 3.x and earlier offer.

  From 4.0, there is a new model of licence for AnyConnect. It is explained in the Guide of command AnyConnect. While it is not currently applied by technical means, use of AnyConnect 4.0 requires having a license to do so.

  For some additional supporting documents as you initially requested, see also "Feature Licenses" of the Configuration Guide of the SAA.

  * Some models do not support remote access VPN and either do not have the feature available or cannot use the license - for example ASA 1000v and an ASA working in multiple context mode.

• Please notify PIX or ASA

  Hello

  Could I have your opinion on which is best as a Firewall/VPN device. The network, I'm looking to deploy the device has a Web server and a mail server with Outlook Web access that require access to the outside. There are a few servers that need remote access also, so I thought I'd use 3DES IPSec VPN tunnels for users to access the LAN.

  I used and configured the before PIX 515 firewall on the network using Cisco VPN Client software to access LAN remotely, so I am to some extent familiar with this technology. But I'm not familiar with the ASA devices though and hoping for an opinion on which is the most profitable, straight forward and easier to deploy?

  Thank you very much

  Mark

  Mark,

  I highly recommend that you integrate the new product ASA against the PIX, as you may already aware that PIX platforms have reached end of life. If you were in a scenario where you were using PIX515 and are looking for additional has this PIX 6.3.5 code does not, it would be possible to switch the code to 7.x-8.x on 515 for example to take advantage of much reacher features in code 7.x and higher. But it seems that this is not the case, if you are looking to implement a new security ASA5500 serial b.b.q look.

  If you are familiar with PIX you'll be fine, of course, there are new features to learn and a completely new architecture, but the basic concept of the firewall and traffic control remains the same. All your requirements such as VPN L2L, VPN can be realized in addition to other features that you would never see in the code 6.3.5.

  The most important point is to integrate a new platform, not the one that has reached the end of life, it is my personal opinion.

• Router or ASA

  Hello world

  I work in a company that has about 60 users, actually we have a legacy firewall, fortinet with an older version of IOS, we have some problems with the vpn tunnel.

  We decided that we must change the firewall and put something in this place.

  I am responsible for this change and may not take a decision on the device should I put, a router or a Firewall ASA.

  In the future, we will build a headquarters of tunnel IPsec between our company and another seat with its own Cisco router for vpn.

  We also have client different tunnel vpn site between our headquarters and many outside users.

  Then you correct this information?:

  (1) with a Cisco router, vpn Ipsec tunnel are possible without any annual license to pay?

  (2) ASA vpn Ipsec tunnel are possible with an annual license that we should pay?

  3) IF I buy an ASA and build my Ipsec tunnels and stop paying the annual license, my Ipsec tunnels would disappear our stay there, are there problems to wait?

  I have difficulties to make a decision, so what do you think? Please I need some arguments to defend the best choice.and convince others.

  Hello

  Sorry to say that I'm not really familiar with the side of the router Cisco of today. In the past, I have not had to worry Cisco routers VPN functionality, but its my understanding that the routers are more license according to the switches. (For example our ASR1000 routers seem to need a separate license of VPN)

  I'll let someone more familiar with Cisco routers explain details thereon. Somehow I never seem to find specific information about them compared to Cisco ASA for example.

  With an ASA you will not need any licensing when generating L2L VPN and IPsec VPN Client. You can create as many VPN IPsec as the platform supports.

  With respect to the VPN Client, I would say that the IPsec Client is pretty much replaced by SSL VPN Client called AnyConnect which requires a separate license. I saw that the old Cisco IPsec VPN Client software works even with the latest systems but is not something that is recommended use more. Although there are no Cisco IPsec VPN Client also options.

  My personal opinion would be to use the Cisco ASA firewall to your needs. Firewalls and VPN is easier to manage than with routers. Although the Cisco routers would give you more choice and flexibility in regards to virtual private networks. I just personally consider ASA firewalls more user-friendly for your object even if my opinion is naturally a bit biased as I have used Cisco firewall for most and not routers really.

  So in answer to your questions soon

  1.) compared to Cisco routers, I'd prefer someone with more expirience with them answer that question. To my knowledge, you will need to have a license of security to use VPN on the router, but the models I managed have always supported VPN.

  (2.) with Cisco ASA device supports so many Client VPN IPSec or VPN L2L like holders of the chosen platform. No permit required.

  (3.) as the previous response already mentioned. No permit only related to the amount of IPsec VPN. Only the material limit so that you only pay once again for any license related to IPsec VPN to work.

  Here is a fact sheet of the original ASA 5500 series (which is replaced by the new ASA 5500 Series - X)

  http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps6032/ps6094/ps6120/prod_brochure0900aecd80285492.PDF

  Here is a sheet of the new series of ASA5500-X

  http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps6032/ps6094/ps6120/at_a_glance_c45-701635.PDF

  The two document lists the peripheral models IPsec VPN limit

  Take a look at the options above. To be honest with your user quantity arrived you with a lower ASA range model. In the original series of ASA5500, the lowest model is the ASA5505 (model ASA5505, you need unlimited user license or license security more to support the amount of your user Base license supports only 10 users). On the new series of ASA5500-X ASA5512-X model is the lowest model of the end (no replacement model for ASA5505 yet)

  Hope this helps

  IPSec driver successfully stopped

  Hello 3moloz123,

  Crypto ipsec transform-set esp-3des esp-md5-hmac TRANS_ESP_3DES_MD5

  Crypto ipsec transform-set transit mode TRANS_ESP_3DES_MD5

  Crypto ipsec transform-set esp-SHA-ESP-3DES-3des esp-sha-hmac

  1. the reason why the VPN remote access (RA) couldn't form with success before the passage of TRANS_ESP_3DES_MD5 to ESP_3DES_MD5 is the mode of transport is not supported for RA VPN.  You must use Tunnel mode for the processing of IPSec together we must maintain the IP header inside so that, once the package is decapsules and decrypted at the head of IPSec end we can transfer the package.

  In the newspapers, you can see this failure

  29 Dec 18:54: 26 [IKEv1]: Phase 2 failed: Mismatched types of class attributes Mode of Encapsulation: RRs would be: UDP Tunnel(NAT - T) Cfg had: UDP Transport

  Repeat x 4

  RRS of transformation all sent by the RA Client.  Cfg would be is that the dynamic encryption card supports.

  2. the isakmp policy change was unnecessary, the Phase 1 session came fine ISAKMP indicating worked.  Phase 2 begins only after a successful Phase 1 (session ISAKMP).

  After failing to build Phase 2 (child SA) we drop the ISAKMP Security Association since it is not used.

  I hope that answers your questions.

  Kind regards

• IKE Dead Peer Detection between Cisco ASA and Cisco PIX

  I have a network environment in Star with about 30 offices of satellite remote using VPN Site to Site connectivity.  The majority of remote satellite offices have the features of Cisco PIX 501 running PIX Version 6.3.  The hub office runs a version 8.2 (1) Cisco ASA.

  I configured Dead Peer Detection on the Cisco ASA device at the office hub with the default settings of the following-

  Confidence interval - 10 seconds

  Retry interval - 2 seconds

  I think I'm right assuming that raises are limited to 3 before the tunnel is completely demolished.  Basically, the problem that I am facing is with several remote satellite offices.  What seems to be the case, the tunnel between the remote offices and the hub is demolished (probably because of the length of IKE, always 86400 seconds) and the tunnel then fails to renegotiate unless traffic is physically forced from the hub office.  The tunnel NOT to renegotiate after satellite office, ONLY the end of the hub; so that means sending traffic to the satellite when the VPN tunnel is out of service, not to renegotiate the tunnel.  The Hub office is a colo and therefore traffic rarely comes to that end, the tunnel remains so down until manual intervention occurs and the ICMP traffic is forced into the tunnel.

  Should the KeepAlive and retry interval settings corresponds to both ends, for example if the two devices be configured for DPD?

  What are the potential pitfalls to the extension of the life of IKE, and this will help or even hinder the problem?

  Thank you in advance for helping out with this.

  Hi Nicolas,.

  I think that the two DPD settings must match on both ends, if these do not match then problems like yours might arise which seems to happen here, is that one end shows a tunnel down, but the other end may not detect it down, we could have to watch debugs, or record two ends to see if this is the case , setting in the meantime ike DPD for same timers could hetlp on.

  In regard to the increase in the life expectancy of IKE, well you just need to be aware that this could allow keys to be discovered since these are not renegotiated unless the tunnel is down on the level of IKE. Other than that I don't see why this would affect you.

• VPN failover between the ASA

  I do a search in the search of the best solution for switching between two ASA and hoped that someone wants to point me in the right direction.

  The situation is this, we got:

  -Head Office 2:

  Each is equipped with an ASA 5505

  -10 branches

  Each is equipped with a 887 integrated services router.

  Each is BranchOffice must have a redundant VPN connection at the headquarters of these two, and they all need to use the first person as main and the other in high school. In case of failure, all branches need to use the second connection VPN going the second seat.

  In my research, I'm looking for the best possible solution, with faster failover, but have no idea where to start my research.

  I hope someone has a good answer for this one.

  Thank you very much in advance,

  Kind regards

  Dwayne

  I do not understand why people continue to use ASA devices for VPN endpoint.  the ASA is NOT designed for complex VPN scenarios.  It is designed for simple scenarios.  In terms of VPN by using comparison, ASA is a person with a basic education while Cisco IOS is like a person with a college degree.

  For the scenario, you will be much better using Cisco IOS routers everywhere, where you can implement the GRE/IPSec or DMVPN.  Both cases will be sastify to your needs.
