ASA inside access DMZ and return

Hi Expert,

How configure ASA to allow access from the inside to dmz host and also back?

Thank you.

Rgds,

To the Shaw feel Yeong

Hello

By default, access from inside the DMZ is permitted this access is through higher security level to lower the level of security.

Return to inside host traffic is automatically granted by ASA/firewall if the connection / translation is valid / exists.

Example:

Inside of the intellectual property: 192.168.1.1/24

DMZ: 172.16.1.1/24

2 two ways to do:

a. use nat & global command:

Global (dmz) 1 172.16.1.10 - 172.16.1.20--> help de.10 a.20 will be used inside hosts to access dmz

Global (dmz) 1 172.16.1.21--> all inside will use this IP like PAT, if the above range is fully used.

NAT (inside) 1 192.168.1.0 255.255.255.0

Note:

-Use the ACL if you need to control the type of service to pass through and apply on the inside of the interface.

b. static use of translation between inside and DMZ subnets:

static (inside, dmz) 192.168.1 192.168.1.0 netmask 255.0.0.0

Note:

-This will allow inside the host to initiate & access dmz and dmz to initiate & access to the inside (initiate connection to dmz host). When DMZ accessing inside the host, DMZ use inside physics/assigned host IP.

-Use the ACL if you need to control the type of service for cross and apply on time interfaces dmz & Interior.

Example of configuration:

http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a00806745b8.shtml

* Watch under command "static (inside the dmz).

  • Connection interface ASA inside and DMZ

    Hello

    I'm moving my current Internet/VPN link to a double link on different ASA and ISP providers.

    I want to create an INTERIOR on my ASA 5545 x interface that will connect directly to my Nexus 7 k Distribution or tanks

    The interface inside the ASA5520 is currently a virtual local network that was created on the Nexus 7 k.

    It seems simple enough to follow this same design, but using the different VLANs and the intellectual property regime.

    I also need to create an interface DMZ on the SAA on my distribution of Nexus 7 K device.

    Currently the ASA5520 DMZ interface comes from a VLAN that was created on the SAA and then to shared resources

    It seems simple enough to follow this same design, but using the different VLANs and the intellectual property regime.

    Is there a best practice approach document or advise that someone would pass along

    Models reference Cisco Secure Data center not dier DMZ. However, it is a very common configuration for the ASAs.

    Real wrinkles come in on the side of switch. You have the option to use physically separate switches (which you have already decided not to do), and a core of Nexus 7 k, the next option is to know how to separate the DMZ and the inside of the safe areas. The most secure, with a standard kernel k 7 would be to create a second VDC for the DMZ with no layer 3 services and have interface DMZ of the SAA to be the default gateway for hosts. A second option on the 7 k would be to stick with a VDC but put the DMZ VLAN charge either in their own VRF or simply once again make L2 only on the SAA with the ASA being the L3 bridge.

    There are several other approaches that you could take, but those that I have just described is the most commonly used.

  • Can I access a label inside a MC and then return to the main time line

    Here is my current set up.

    I have a section marked on the main timeline that has the icons of 12 different videos. Each icon acts as a button and brings a user to a section marked with a FLV Playback component work video to play the corresponding video. These marked sections are located on the main of the time.

    This methog is my very long time mainline. Is there a way to do an additional MC which will hold all the buttons of the video and then have this MC separated in marked sections.

    In other words can I access a label inside a MC and then return to the main time line?

    My current code to access the label placed on the main timeline is:

    HowTo_maininfo_mc.theArrangement_btn.addEventListener (MouseEvent.CLICK, theArrangement_btn_amimated_btnDown);

    function theArrangement_btn_amimated_btnDown(event:MouseEvent):void {}

    gotoAndPlay ("theArrangement");

    }

    What it would be like if my "theArrangement" label would be located inside a MC?

    Is there a specific code of if I want to have a close button located on the label inside a MC and he needs to get on a label located on the main timeline?

    You should have an image with an flvplayback component and having each button assign the variable value from a source that is used by your component:

    var sourceVar:String;

    function theArrangement_btn_amimated_btnDown(event:MouseEvent):void {}

    sourceVar = "arrangement.flv";  for example

    gotoAndPlay ("flv_pb");

    }

    ///

    and as part of the "flv_pb", use:

    yourflv_pb.source = sourceVar;  where yourflv_pb is your component instance name.

  • Access DMZ

    Reposting because it has got a little buried...

    I have a PIX 515e with a DMZ interface. This interface is an FTP server.

    I can access the internet from inside LAN and DMZ server. The internet can access the server in DMZ for FTP - ing. However, the inside LAN cannot access the FTP server. I have a static mapping inside the DMZ:

    static (inside, dmz) 172.16.255.254 192.168.40.250 netmask 255.255.255.255 0 0

    But when I try to access the FTP, it indicates that the connection is refused. I don't have an ACL configured to allow access. I didn't think I should because I'm leaving a higher to a lower security zone, but maybe I'm wrong.

    I also tried the bit 'alias' another post. No luck.

    The PIX version is 6.3 (3). The IP address of the client is 192.168.40.10, the IP address of the server in the DMZ is 172.16.255.254. Fixup protocol ftp 21 is enabled. The syslog says:

    305006: failure of the creation of translation portmap for tcp src Interior: 192.

    168.40.10/51886 dst dmz:192.168.40.250/21

    I looked in a few places to see if I could find a resolution based on what I saw in the system log, but it seemed that few suggestions were applicable. One who was (by emptying the translations) has not helped.

    Thank you very much everyone, you all have really helped.

    Hello

    You must have the 'inside access management' command configured on the SAA.

    If you run a 8.3 software or newer on the SAA, should also look at the configuration 'nat' IF the above command solves your problem

    Hi all

    I was deploying new site to site between ASA 8.0 (HQ) and ASA 8.4 (branch). Everything works fine but I have a problem on the ASA-reach remote that I can't manage branch ASA with inside the interface IP address.

    My setup on remote ASA

    • Client time-out see demand
    • When debug icmp on ASA remote then ASA show only ICMP request to HQ no response back from remote ASA

    I'm not sure whether it's a bug on ASA 8.4 or not because I can manage a remote other ASA what version 8.0 software HQ

    Thanks in advance

    Do not know what 8.4 version you use, but it is broken in the 8.4 (2), I stumbled upon the upgrade from same problem. SSH and ASDM will not connect through a VPN L2L interface inside. This worked well in 8.4 (1).

    Even after the "split-tunnel-policy tunnelspecified" specification with "split-tunnel-network-list value TUNNEL of SPLITTING" and denying all traffic to the public IP address of the ASA, I'm still not able to SSH in the firewall. Everything else seems to work OK, but I have to be able to handle the ASA from the public interface. In fact, I expect little given the mean one sa is the installer for the tunnel, and it would seem that a deny statement would be ignored, but perhaps there is a way around this. Thank you.

  • Cut and paste tabs and "returns"?

    Hello

    In an earlier version of pages, I could copy and paste tabs, as well as breaks line or "go back". I use this feature a lot then the processor who ends up going inside a spreadsheet and visca versca.

    In the most recent version of Pages, I think that cutting and pasting of the tabs is available in all simply copy the tab character and paste it into the Find/Replace dialog box. (And a shortcut of 'Option-tab' inserts a "tab" character in the Find/Replace dialog box.)

    But cut and paste newlines or line returns no longer seem to work (or fact is old keyboard shortcut 'Option-return'.  This feature has gone completely outside, or modified or?

    Anyone know?

    Thank you!

    Rick

    Just tested the latest version of the Pages.

    Option-tab peut be used in the dialog box search to search for a TAB

    I can select a tab in the text and paste it into the search box and it is as expected

    Shift + return produced a line break, and this also can be copied and pasted into the Find dialog box

    I can't locate 'Find & Replace"of carriage return anyway, page break, column etc. break section break that had Pages 09... most have disappeared when Apple introduced 5 Pages.

  • Compare multiple columns and return a different value

    I have more access to excel and I'm running my previous workflow in numbers of duplication of issues.

    I have a worksheet when a sheet with all my power tools.  On the "Power Tools" sheet I have columns for the brand, Type, model, purchase date, etc...  An example of this would be: pass a "DEWALT", "Jackhammer" Col B, Col C "DCD995M2" and so on.

    I have a second sheet in the same document which is my front end if you want.  I wanted to have selections for this dynamic drop-down list but it seems it is not possible without scripts, but is not the immediate question yet I'm the mention the case where someone knows a good fix.  The second sheet "Sorting Test", I created manually drop-down boxes, one in column A of the brand and the other in column B for Type.  I'll choose the brand and type and I want numbers autofill the rest of this line based on these two selections.

    Example:

    In the 'Sort Test' sheet I select DEWALT in column A and I select the drill in column B and I want DCD995M2 is displayed in column C and the purchase date in column D and so on.

    Excel in it would be a game table or something similar.  So far every site and search google only gave a lot of people who try to do VLOOKUP or correspond to errors, but I've really met anyone corresponding to two distinct cells from two separate columns and return data from this same line a match was found on.

    I must also mention I'm really trying to avoid adding a hidden line that combines some of these but I know it's the most noticeable work around.

    Basically, I want to match two selections separated against two separate columns, and when it finds the match, I want it returns a different value of this corresponding line how I got everything just copy this formula on adjacent cells and simply adjust to the column in the same row matched.

    I know that I shouldn't do this on separate sheets, but it's just a choice that I made a point of design.

    Any help would be appreciated, because I'm trying to really get the most out of the numbers, especially with how it syncs between desktop and mobile and I have more access to Excel.

    You can it as what you do and why?  This will help us understand what drives the design.  Leave out how to solve the problem,

  • error message trying to run a clean boot "an access error was returned while trying to change a service."

    While trying to solve a problem with IE 8, I have a problem trying to run a clean boot.  When I start up I get a message on change in the config file. Click ok and sys config is displayed. Now, if I make a modification, OR not, I get an error message - "an access error was returned while attempting to change a service. You may need to log on using an administrator account to make the specified changes. "First of all I am logged on as administrator, secondly I get this error even when I select"normal start ". I used the clean boot before without problem.  Any ideas?  I am running win xp sp3.  I started having problems after the sp3 upgrade.

    Given that you are not using the standalone SP3 Installer AND since McAfee was working at the time of installation, that's what I'd do (well, I would do it only if I was almost 100% convinced there was no malware on my system):

    1. download the McAfee removal tool.

    2. download the installation file for the free version of Avira AntiVir.

    3. download the standalone SP3 Installer.

    4. download the standalone installer of IE8.

    5. physically disconnect from the Internet.

    6 turn off the automatic updates (temporarily).

    7 uninstall McAfee.

    8 run the McAfee removal tool to make sure that all other loose ends are supported.

    9 Uninstall SP3.

    10. run the system restore, select the before date SP3 has been installed.

    11 uninstall IE8 (and IE7, if necessary). Reason: It is important to be at the level of IE6.

    12 install the SP3. Reset.

    13 Installing IE8. Restart twice.

    14 install AntiVir.

    15 re - connect to the Internet.

    16. download and install the update of AntiVir.

  • How to execute a Perl script and returns the value as a string?

    Hi, I am trying to build an application using the eclipse 2.0.0 with the Blackberry SDK 7.1 plug-in. currently I tested Simulator 9900 version 7.1.0.523. I need to use the Perl language to access the raw biological database and returns as a string without having to write a longer program using java.

    In a stand alone Java SDK, I can use the line:

    Process p = Runtime.getRuntime () .exec ("perl script.pl")

    but when I tried to use it on the IDE for a Blackberry project, the project will not compile. It is said:

    Method exec (String) is undefined for the type of Runtime

    Hopes, can someone show me the correct syntex to use, but if no class is available, could someone show me a sample for unified research process? The names of blackberry dev is very complicated, I can't find any samples for her.

    Thank you.

    Seems interesting.

    Your idea was to download the data to the BlackBerry and then directly execute queries.

    Although there are a number of other obstacles, the first fall you in East platforms supporting Perl.  Here is the list:

    http://perldoc.Perl.org/perlport.html#supported-platforms

    BlackBerry OS Java is not included - in fact the only ' included phone OS is Symbian.  Interestingly, it seems likely that PlayBook and BB10, because they are based on the QNX operating system.

    If we discard Perl as a query language, then you will need to provide another option to search.  I think that unified search is an option, but you will have some work to do to use it.  The first thing you should do is find out if in fact, you can download the database on the BlackBerry.  The only available on the Blackberry database engine's SQL, so if you want the database can be exported to a SQL database, there is a chance that it would work.  I had a quick glance around the site, and I can't tell what the "database" is in the format.  Then I suggest that look you at that next.

    I hope this helps.

  • Problem with the Cisco ASA 5525 X SFR and Firesight high school

    Hi team,

    We have two ASA 5525 X installed on them and Firesight in a Linux VM whose two SFRs are registered with SFR failover mode. We use the SAA secondary off the hook if the primary fails to turn on the secondary manually switch the wan cable. I turn on the ASA secondary every weekend to take the configuration of the primary for the ASA and the SFR and close by button walk / stop.

    Last week I turn on high school ASA and the Firesight couldn't see the secondary SFR and show the message below:

    Module device heartbeat: device > don't send heartbeats.

    (I should mention I can Pinger the IP ADDRESS)

    I tried to study the problem without success.

    I also deleted the sensor just Firesight devices management in case something is stuck, and I'm trying to re added without success.

    I'm new in firepower so... any ideas?

    Thank you

    Finally, this problem has been resolved by the redefinition of firepower:

    see detailed here procedure to perform this redefinition;

    http://www.Cisco.com/c/en/us/support/docs/security/ASA-firepower-service...

    Before that, it appeared that firepower was not very healthy:

    After a success "" configure Manager add xxxxx"command.

    the command of managers show show nothing;

    He should have shown this result:

    > Display managers

    Registration key: AZERTY
    Inscription: pending
    State of the PRC:

    on the other hand, in expert mode, the following command shows several processes (and not in the normal state):

    sudo pmtool status | grep-i down

    Last point,

    After the recreation and reconfigure all this fire power, installed in the ASA secondary standby, was considered to be OK under Firesight health Monitor,.

    but after 10mins, it appeared in critical condition with the following message:

    "Interface"DataPlaneInterface0"receives not all packages.

    This is normal and due to the fact that Eve ASA receives no flow and the same goes for firepower inside this ASA;

    by performing a failover from the primary to the secondary ASA, this critical message disappeared for firepower inside the ASA Sec and appeared for firepower inside the ASA elementary school
