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.

  • "ITS creation failed" problem for IPSec VPN

    An ASA 5100 is used to provide VPN access for my business.

  • Ask/dissemination of certificates for IPSEC VPN user

    Hi all

    I have therefore an ASA established the connection to an LDAP, an SSL certificate signed for the cert of the device and use IPSEC IKEv2 VPN connections that are authenticated by the LDAP username and password and X.509 certificates.

    I have a CA server root of Microsoft Windows server 2012 (State in offline mode) and a Windows server 2012 subordinate certification authority server. Both are 10-year Certification authorities.

    To generate certificates VPN I'm going to the AC Sub, go to certificates (local computer) > personal > right click on the white space > all tasks > advanced operations > ask personalized.

    I have set up my cert accordingly and enable private key export.

    I submit new request to the CERT service. authority on the CA of Sub (same machine as before). I issue the certificate, and then export the certificate with the private key. I send this to my user, then they install this certificate in the personal certificates store and access the VPN access using this cert more username and password they have been assigned (no there is no possibility for them to ask their own PC)

    Question 1: Is there an easier way to do this? Command line? Script? preconfigured with the certificate settings .ini file?

    Question 2: These certificates are only 1 year. How can I generate certificates that are longer than that. I'm jumping for 3 years.

    Thank you!

    BROKEN

    Well it's quite simple setup-wise when you chose to go down the path of the client certificate. It is generally easier to use SCEP (Simple Certificate Enrollment Protocol) Protocol to manually deploy certificates. There is an example of a configuration Definition here.

    There is also a good presentation (or several) of Cisco Live. I recommend that you take a look at this one from 2012: Practice of PKI for VPN.

    In this presentation, he you (slide 39) specifically shows how to create a new certificate template and set the validity period for the value by default 1 years.

  • 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

  • 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.

  • 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.

  • IPSec VPN with compression

    Hi all

    I find this compression of supporting IPPCP 2600XM for IPSec VPN. It seems that it is supported only with a VPN module, is it?

    What would you say if I don't have module VPN, but the IPSec VPN configuration and compression for a connection low speed?

    BTW, the IPSec VPN and "compress stac" can co-exist?

    Also, what kind of compression support in 28xx with IPSec VPN?

    Thank you very much.

    MAK

    MAK,

    It depends on the installed vpn module. The previous support compression, but the compression is performed in software, not on the card, which offers only encryption. For this to work, you must run IOS 12.2 (13) T or later.

    If your previous IOS running, you cannot use compression alongside encryption PURPOSE cards at all.

    The latest maps AIM-VPN /? P II IPPC support in hardware.

    More information is here:

    http://www.Cisco.com/en/us/products/HW/routers/ps259/products_data_sheet09186a0080088750.html

    This link displays information related to the release of functionality of software compression of 12.2 (13) T

    http://www.Cisco.com/en/us/products/SW/iosswrel/ps1839/products_feature_guide09186a0080110c00.html#1027177

    Thus, the options you have depend on the IOS and the card BUT you have.

    Beginning IOS and card without compression

    12.2 (13) T and IOS beginning, hardware encryption software compression

    Last map and supporting encryption and hardware compression IOS.

    I'm unsure of the 2800 series, I expected that they support the latest novelty of compression and hardware encryption.

  • AnyConnect 3.0 supports IPSec VPN for remote access?

    Hello world

    I've read about Cisco AnyConnect 3.0 issues that it supports IPSec VPN for remote access:

    http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps6032/ps6094/ps6120/qa_c67-622477_ns1049_Networking_Solutions_Q_and_A.html

    Can someone point me in the right direction to get IPSec VPN AnyConnect 3.0 work?

    Thank you in advance!

    Hello

    Takes AnyConnect support IPSEC from version 3.0, but only in combination with IKEv2.

    There is no option to use a CPF file with it and the config should be pushed through a profile Anyconnect.

    More information on this:

    http://www.Cisco.com/en/us/docs/security/vpn_client/AnyConnect/anyconnect30/Administration/Guide/ac02asaconfig.html#wp1325361

    You should also change the ASA config so that it accepts negotiations IKE v2:
