PIX - Polo or not in function external interface used

I'm still digging into that, but need not NAT all traffic begins inside for 2 of my low-security interfaces (dmz1 & dmz2), but have the same traffic PATed at the address of the interface if it goes on the external interface.

I use nat (inside) 0 0.0.0.0 0.0.0.0 for the necked traffic that goes inside to dmz1 & dmz2. Then, this prevent me to put in another statement of nat [like nat (inside) (1 0.0.0.0 0.0.0.0)] as causing an error message saying the nat statements overlap. Makes some sense.

It looks like a "static (inside, outside) interface 10.1.1.0 netmask 255.255.255.0" would be the ideal solution. But I get an error message "Invalid netmask interface option" when I try to enter that. So, who should not be able to address groups. It also won't let me do a static unique to the address of the interface, so that's going to not steal even though I was ready to toss around all the guests individually.

I was hoping that static control let me to overload all inside responds to the address of the external interface when the data is out the 'external' interface, while the "nat (inside) 0" Let me NAT not nothing will dmz1 & dmz2, but not dice. "»

Any thoughts on what I'm missing here? It must have a way to do.

Thank you!

Have you tried that?

Let's say you have:

192.168.0.0/24 inside

192.168.1.0/24 on DMZ1

192.168.2.0/24 on DMZ2

permit access ip 192.168.0.0 list NoNATinside 255.255.255.0 192.168.1.0 255.255.255.0

permit access ip 192.168.0.0 list NoNATinside 255.255.255.0 192.168.2.0 255.255.255.0

NAT (inside) 0-list of access NoNATinside

NAT (inside) 1 192.168.0.0 255.255.255.0

  • Telnet on PIX with the external interface

    Is there a way to telnet in PIX Firewall through the external interface?

    SSH is a valid method to access the site, but I wonder if there is another way to do it. PDM is another tool for access and modification of the configuration.

    Any help will be useful.

    Best wishes

    I'm pretty sure that Telent directly to the external interface of a PIX is not available. It is such a big security risk that it is not offered as an option.

    SSH is a much better way to go (even if it's only SSH1).

    You can probably VPN in your network and Telnet from inside.

    Good luck

    Help, please

    Yes, if your external interface is mapped to y.y.y.y, then you will be not able to ssh to x.x.x.x as it will be pass on to y.y.y.y.

    You can change the static 1 to 1 to the port for each particular port address translation you need sent to y.y.y.y.

  • Static and VPN on the external interface

    Hello

    Can someone tell me if it is possible (and if so, how) do vpn enabled on the external interface and to have something like:

    public static x.x.x.x interface (indoor, outdoor)

    IE: I have two addresses ip - one for the router an e0 on the pix. I create a static and lists of access to allow inbound http/https server inside but I also want to allow vpn hit e0 and work. My configs work if I use an ip address 3 for the static, but not if they share. I can imagine that the static method takes the vpn traffic before the pix can use it OR maybe as the pix has no route to the now (due to the static method) that it cannot answer?

    Hope I'm making sense

    Thanks for the time spent on this

    see you soon

    Andy

    I think you want something like this:

    public static tcp (indoor, outdoor) interface http 10.10.10.10 http netmask 255.255.255.255 0 0 (where 10.10.10.10 is your web server)

    public static tcp (indoor, outdoor) interface https 10.10.10.10 https netmask 255.255.255.255 0 0

    access-list 101 permit tcp any host x.x.x.x eq 80 (where x.x.x.x is your IP interface)

    access-list 101 permit tcp any host x.x.x.x eq 443

    Access-group 101 in external interface

    It will be useful.

  • Secondary public network on the external interface

    We already have a range of public address configured on the external interface (213.XX. YY. ZZ/29). Our supplier we've assigned a new range of public addresses (62.XX. YY. ZZ/29).

    How can I configure this on the PIX?

    PS: as far as I know, the secondary addresses are not possible!

    Hello

    You don't need to configure anything on the PIX make you just as your ISP routes the new addresses to your PIX - then you can use the new address to what you like.

  • Internal network can not access the external IP

    I recently installed a firewall 506e to include a new IP block for our external interface. Origionally we used a PIX 515 to do a larger block of the IP, but he has run out of space.

    I have set up the new block on the 506e and tested out successfully connectivity. I am able to ping and connect to internal an external network computers, but the internal network will NOT connect. Pings or HTTP tries the deadline. Here is a sample of the config that is used:

    access-list 101 permit tcp any host 207.219.xx.xx eq www

    static (inside, outside) 207.219.xx.xx 192.168.0.65 netmask 255.255.255.255 0 0

    Access-group 101 in external interface

    Please note that the internal network is NOT going through this PIX to reach the outside world. Only the machines that use the new IP blocks use this PIX.

    All internal addresses are 192.168.0.x, regardless of which is their default gateway.

  • OnLoad ActionScript external interface

    Hello

    I have this external interface code that sends a url of the video to a video player when a user clicks on a button, it goes something like this:

    < script language = "JavaScript" type = "text/javascript" >
    {$(document) .ready (function ()}
    function callJavascript (sendText) {}

    window.document.myMovie.SetVariable ("testValue", Mathias);
    }

    });
    < /script >

    The code above works well when a user clicks a button with onclick the variable passed is a url of the video

    and is sent to the player.

    The problem is I want to get the video url passed when the page is loaded.

    I tried.

    < script language = "JavaScript" type = "text/javascript" >

    {$(document) .ready (function ()}

    var sendText=$("Videosroll/Videos/1.flv").val ();

    window.document.myMovie.SetVariable ("testValue", Mathias);

    }

    < /script >

    It does not work. I think that its because the videoplayer is not fully charged when this action is invoked.

    I looked at javascript timers etc. If anyone has a solution please help.

  • Is it possible to call the function in the module through function of interface component

    Hello

    I see this in the livedocs.

    "In general, if you want to set properties on controls in the module using external values, you must create the variables that may be related. Then, you set the values of these variables in the methods implemented in the interface. If you try to set properties of the controls of the module directly using the external values, controls may not be instantiated by the time the module is loaded and the attempt to set the properties may fail. »

    I have a component in a module. I have to call this component of the interface function funcion. That is to say my main application call the function of interface, and that interface funcion must call funcion of the component. Is this possible. I get error that the element is null, if I try this. Is it possible to do so.

    Thanks in advance.

    Hi, yes I got your problem now when I have your code.

    See it here:

    MOD = modInfo.factory.create (like TestInterface);
    var el: IVisualElement = modInfo.factory.create () as IVisualElement;
    this.addElement (el);

    It won't - you create 2 separate instances of the module, which you create - 'el' and the other a not - "mod".

    It should look like this:

    var el: IVisualElement = modInfo.factory.create () as IVisualElement;
    Note: I usually use var el: Module = modInfo.factory.create () like Module; Does not need at least for the moment to cast as IVisualElement but I know that it is not bad, I read in some articles before getting if I remember correct it does not give access to some methods, but not sure.

    MOD = el like TestInterface;

    addElement (el);

    First, you create the instance of the module with the factory.create (), and then cast you to the interface.

But when I use the external Interface in AS2 class, Internet Explorer displays the page OK and directed the film, but it does not have the JavaScript function I call you and gives me an error of yellow triangle of "flash is not defined" in line 1.

    I tried the publication of version 8 and version 9 player. And there is no error in Firefox, which runs my JavaScript code and HAVE it all just great. (Yes, big surprise.) The AS code is quite simple...

    Holy Batman tracks, you're a God indeed! Flash has been automatically creates the Object and Embed tags when you publish the swf file. But I noticed in your article, when you discussed what punctuation marks were acceptable for the ID, oblique were not among them.

    Since the movie is leftmenu.swf and is located in the flash subdirectory, the name and ID that was flash/leftmenu. After mucking, I found that the problem was in the AC_FL_RunContent function (also automatically created when the movie is published). When I changed the 'id' attribute it simply be leftmenu, IE and Firefox have both pleased, and I didn't have to make any other change. Go figure.

  • "Lack of function external lvanlys.dll ' when executing EXE

    Windows 7 x 32, LV2009SP1 / LVRuntime 2009

    I am trying to build an EXE from a customer code.  They use the analysis library (NI_AALBase.lvlib).

    It works well on my dev machine.  When I create the EXE file and place him on a target with LVRuntime on that machine, I get the error:

    Lack of function external lvanlys.dll: Mean_head:C NI_AALBase.lvlib:Mean.vi.

    I explicitly added the lvanlys library to the project.  I added the library as a source file in the build.  Finally, I added the DLL itself to the project and as a source for the build.

    Still the same error.  The DLL is located in the folder data after construction.  I tried to move it in the same folder as the EXE file and in the system32 folder.  Nope.

    I just changed the extension of the DLL to dllx and tried again, and I get the same error, so it looks that it can't find it.

    Do I need to register this DLL or something?  Is there a file?

    You are an installer of construction or simply transfer the executable file?

    If you are just transferring the executable file, make sure to include the folder "data" beside him.
