IPSec VPN in the context of security... Static interface or not?

Hello

For the moment, I have a pair of ASA5510 in context configured Multiple. Everything is ok, but we use til now only the ACL functions.

Now, I would be interested in configuration 2 contexts, with IPSec VPN. A VPN by context. But I can't find any information if it would be possible to use a common interface for both contexts. My wish would be only to spare public IPs...

If I have to configure VPN 100 100 contexts, I need 100 public IPs?

Thanks to anyone who can give me a tip,

Kind regards

Olivier

Hello

If you have separate IP addresses on the same subnet, you can reach these interfaces to different contexts

You only configure a sub with a interface ID Vlan that is connected to the gateway of the ISP. You can join this subinterface settings as much as you want but the IP address on the interface must naturally be different in each context. To my knowledge ASA really prevent you from setting up the IP address if she sees him in a different context in the same subinterface.

    Hello guys,.

    I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

    The question statement not the interface pointing to ISP isn't IP address private and inside as well.

    Firewall configuration:

    Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

    Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

    I have public IP block 199.9.9.1/28

    How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

    can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

    If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

    I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

    Please help with configuration examples and advise.

    Thank you

    Eric

    Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

    3 options:

    (1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

    OR /.

    (2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

    OR /.

    (3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

  • Captivate 8 - "Audio" in the context of a fast action is not playing audio

    Hello. I was hoping you could help me, because I can't understand why what I'm doing doesn't work.

    I have a slide where I explain the answers to a game earlier in the captivate. Each question is a hyperlink that runs a tip action. This action is currently a set group of objects (box highlight to hide the rest of the screen) and two boxes with text captions. From the top of each box has a red X that I use as a button. Clicking this button launches a tip action that hides everything simply all these objects.

    The screen without a caption box:

    Screen.png

    The screen with a caption box:

    Screen w caption box.png

    My calendar:

    Timeline.png

    I try to add audio to the text explanations, but cannot get the sound to play. I edited stocks advanced for hyperlinks read 'H1 Show' (objects grouped for that matter) in the first line and "Play audio H1.wav" in the second line. I also changed the advanced actions related to the red Xs 'Hide H1' and 'Audio triggered Stop. "

    advanced action 1.png

    advanced action 2.png

    Unfortunately, when I do that, the sound does not play. My limited knowledge of captivate, update the advanced actions on what you see above should cause an audio file specific to play when they click the hyperlink and the beep to stop when you click on the red X. Currently, the audio does not play.

    Does anyone know what I have neglected to make it work correctly?

    Thanks a lot for the answers.

    It must indeed work, don't have time to test and do not immediately see the problem.

    However, would it not easier to fix this audio clip text in the Hx group? He will play only when the group is displayed.

    Update: I tested this out in Captivate 9, with the example, I created for the blog: play with Captivate 9 - Captivate blog

    It works perfectly for me: I added an order of audio playback to the joint action, I used to show the lightbox and stop triggered audio to the action of the close button.

    I have test browser both browser HTML to check if it works for output SWF and HTML. For such an order, that I never had the experience that I should have to publish to make it work, maybe I'm lucky.

    It's common action, I used to change the State instead of display Lightbox, the Show action is for the close button.

    For the close button:

    Sorry that I could not test it on 8.

    Jesse,

    One of the solutions to your problem is to apply the same for both interfaces crypto card and have the two counterparts mentioned under a crypto map entry.

    Since you're using track/IP SLA to activate a single link to a single IP address of time will be answers.

    http://www.Cisco.com/en/us/docs/security/ASA/asa84/command/reference/C5.html#wp2278871

    Have several inputs card crypto with the same statement in game will cause problems.

    Hope that makes sense.

  • How to pass a value to the form defined in the context of security file name?

    Hi all

    Yet to learn JavaScript... I have a JavaScript script, save a copy of my pdf to a location on my machine. Got the privileges of working well as well.

    How I spend in the field values for the file name? Right, the created pdf copy is now called .pdf [object scope]. Instead, I want to use dynamic values of in the form itself.

    Then this.documentFileName gets me the name of the file (Code record trust)...

    var mySaveDoc = app.trustedFunction (function (doc, subName) {}

    app.beginPriv ();
    var myPath = "/ c/SubInspectionForms /" + this.documentFileName + ".pdf";

    saveAs is the only privileged code that should be placed
    with beginPriv/endPriv
    doc.saveAs ({cPath: myPath,})
    bCopy: true,
    ({bPromptToOverwrite: true});
    app.endPriv ();

    });

    this.getField("INSPECTION_Location") doesn't the value of a field:

    var mySaveDoc = app.trustedFunction (function (doc, subName) {}

    app.beginPriv ();
    var myPath = "/ c/SubInspectionForms /" + this.getField("INSPECTION_Location") + ".pdf";

    saveAs is the only privileged code that should be placed
    with beginPriv/endPriv
    doc.saveAs ({cPath: myPath,})
    bCopy: true,
    ({bPromptToOverwrite: true});
    app.endPriv ();

    });

    The script on my SaveACopy button is:


    subName var = this.getField ("INSPECTION_Location");

    mySaveDoc (this, subName);

    I need the value of the field in the function?

    It is easy to think 'this. GetField"is a universal thing you can still use, but it is not. Read carefully the description of the object "Thi". It is set in some contexts, and I don't think this is allowed when using it. You must pass it as a parameter in a context where it is defined.

    Hello

    The only places where you can add separate menu options lies in the command menu or add new extensions that appear in the windows-> menu other panels. There is no other way in which the menus can be added without being replaced by the Flash Code.

    For more information about adding separate entry into the menu commands or the Windows menu.

    (Menu) - add the jsfl script to C:\Users\\AppData\Local\Adobe\Flash CS6\en_US\Configuration\Commands

    and that automatically will be appear on the Menu commands on Flash raises.

    (2) add a (panel) for the C:\Users\ Flash SWF\AppData\Local\Adobe\Flash CS6\en_US\Configuration\WindowSWF folder.

  • Context with IPSec VPN

    Hi friends,

    I have a question for the scenario below.

    I need to create a Site-Site IPSec VPN in the firewall mode.

    Is it possible to create the tunnel.

    I have ASA 5510 Security Plus with Ver 8.3

    Thanks in advance.

    In your case, you ASA in multiple-context to allow VPN to the amp.

    There is no problem with that.

    The only restrictions are that an ASA in multiple context will not work as a VPN endpoint (apart from a tunnel admin)... but you can pass the traffic or VPN traffic as in ASAs in simple mode.

  • Bypass the router upstream company ACL with IPSEC VPN

    Hello

    My headquarters has a routing infrastructure company. I want to configure a Site VPN to IPSEC as a solution of webvpn AnyConnect for my users through the company. If the security guys to create an ACL on the router upstream from my Cisco ASA 5585 to allow IPSEC between 28 (the stretch between my external interface of ASA and the trunk of PO on the upstream router) then I can send ip a whole between my inside interface subnet and subnet within the interface on the ASA distant (still on the company's infrastructure holding constant and correct routing. In short, if a packet is encrypted in an IPSEC packet, IPSEC is not filtered, you can send any traffic, even if it is AS restrictive on a router upstream of the LCA, correct?

    Thank you!

    Matt

    CCNP

    You are right, the router can not look in the VPN package. So anything that is transported inside the VPN, it bypasses security company-ACL.

    For VPN traffic to your ASA, you need the following protocols/ports:

    1. UDP/500, UDP4500, IP/50 for IPsec
    2. UDP/443 for AnyConnect with SSL/TLS, TCP/443
  • SA520 and Question IPSec VPN RVS4000

    Hello

    I installed an IPSec VPN for one of my friends for his company. At its principal office, I installed a Cisco SA520 and he uses to connect devices such as the iPhone and iPad via the IPSec VPN. He uses this fact because he travels abroad a lot and he has problems with services such as Skype is blocked in some countries. This configuration works very well.

    It also has a Cisco RVS4000, which he would like to install at his place of business to the Mexico. He would like the RVS4000 VPN configuration to the SA520 in his office. The SA520 in his office has a static IP address. The RVS4000 to the Mexico does not work.

    Is it possible to Setup IPSec VPN between a SA520 with a static IP and RVS4000 address that does not have a static IP address? If so, examples of configuration would be greatly appreciated.

    Thank you!

    Hi William, simply sign up for a dyndns account or similar service, the RVS4000 configuration will be the same, instead of the IP, you'd be using the dyndns name.
