PIX with H & S VPN DMZ hosting web server to the hub

Ok

Heres a problem which I think would be quite common for these even remotely conscious of security. Unfortunately, my knowledge of the PIX (as well as other Cisco devices) is still in phase of 'growth '.

So, here's the problem. I have a WAN put in place with PIXen and SonicWalls, we are set up in a design essentially Hub and Spoke (fine ok so it is partially meshed). We recently decided to pull the trigger on getting a 'real' web site and everything went relatively well that getting up and rolling. (even with my notice of 3 days/deadline), but here's the problem: I set up the web server on the DMZ to the hub pix, and I figured out (the easy part) how to set things so in the Home Office, people can connect to the web server by using the internal address, but I don't know what to do for people in remote offices with VPN home connections. I tried to define static routes, I tried to add the DMZ to the VPN trigger, I tried to do both of the last things together, and I checked that I have rules allowing traffic to the VPN outside the DMZ on the inside. So, what else can I I get?

I have no problem by configuring a PIX for all basic ups and VPN even at this stage, I can do most of it through the CLI (even if I still want to do more through the PDM). My biggest stumbling block on the PIX has so far was when I actually involve this pesky DMZ...

I actually two PIX in my office, two for my network domestic (one for my place in the States and one for my place in the Japan), so if you can help me, I'll be the two problems and do not forget to give a rating of excellent reviews!

so I guess that leaves me to the place where I scream...

Help!

and I humbly await your comments.

the current pix configuration should look at sth like this,

IP access-list 101 permit

IP access-list 110 permit

Global 1 interface (outside)

(Inside) NAT 0-list of access 101

NAT (inside) 1 0.0.0.0 0.0.0.0 0 0

Permitted connection ipsec sysopt

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

myvpn 10 ipsec-isakmp crypto map

correspondence address card crypto myvpn 10 110

card crypto myvpn 10 set by peer

superset of myvpn 10 transform-set card crypto

interface myvpn card crypto outside

ISAKMP allows outside

ISAKMP key

 address netmask 255.255.255.255

isakmp identity address

isakmp nat-traversal 20

isakmp policy 10 authentication pre-share

isakmp policy 10 encryption 3des

isakmp policy 10 hash md5

isakmp policy 10 group 2

isakmp policy 10 lifetime 86400

now, to add dmz on top of the existing vpn, add the following to the pix (and apply the same concept on the remote end device)

access-list 102 permit ip

access-list 110 permit ip

nat (dmz) 0 access-list 102

  • IPSEC VPN DMZ HOST NAT

    Hello world

    First of all thanks for the invaluable information this community offers technicians everywhere... I'm newish to IPSEC VPN and I have a question.

    I have a DMZ PATed host to a public IP address. I've set up an IPSEC tunnel (with an external body on my outside interface) to allow this host reach a host computer in this organization. The VPN is not come. I am told to implement NAT exemption for the DMZ host IPSEC traffic to the host outside. Kindly, how can I do this?

    Kind regards

    Mumo

    OK, no problem :)

    for 8.2 (5), you can try the following config:

  • second Web server on the DMZ not visible outside

    With the help of a PIX 515e

    I have several Web servers in the DMZ, the first web server and the mail server are set up with the port mapping for the PIX outside IP address of the interface.

    The second and third (inside interface) of the Web servers are configured with static mappings and access lists.

    I can see the first n the mail very good server webserver, but I can not see servers in second or third.

    What have I done wrong?

    I suggest you analysze traffic with the command to 'capture' PIX and sniff traffic on the DMZ and outside traffic.

    Check if packets arrive to the external interface, if it reaches the web server and is at - it a response.

    example of

  • Cannot start web server on the executable file

    Hello

    We have a problem with a Web server - we cannot get to initialize the help of nodes of property or the ini on a compiled executable file.

    As part of our application, we are starting the Web server to publish a status page to be read remotely. This works very well when we are running in the development environment and also when we run an executable a PC with installed development environment, however it will not boot on a PC with just the runtime installed.

    I have attached some of the code that functionally does exactly the same thing in our main application. I used this as my Tester code and built in an exe while trying a lot of different things to fix.

    When executing:

    • The code will sit in the while loop until I press stop.
    • Web server: Active Server = FALSE
    • Out error = ERROR No.

    In the full application the while loop waits a few seconds before throw an error if the server is not started. In this example, I can let the loop running for awhile without leave. Normally, the boot time is<50ms when="">

    It's the ini file to the executable file:

    [WebTest]
    server.app.propertiesEnabled = True
    Server.OLE.Enabled = True
    server.tcp.serviceName = "My Server computer/VI"
    server.vi.propertiesEnabled = True
    WebServer.Enabled = True
    WebServer.TcpAccess = "' + * '"
    WebServer.ViAccess = "' + * '"
    DebugServerEnabled = False
    DebugServerWaitOnLaunch = False

    And it is the Web server configuration file:

    ErrorLog "$LVSERVER_ROOT/logs/error.log".
    LogLevel 3
    The default server name
    DocumentRoot "$LVSERVER_ROOT /... /.. '. "/ www".
    Listen 8000
    ThreadLimit 10
    TypesConfig "$LVSERVER_ROOT/mime.types»
    DirectoryIndex index.html
    LoadModulePath "$LVSERVER_ROOT/modules '" $LVSERVER_ROOT/LVModules "" $LVSERVER_ROOT /... ".
    LoadModule LVAuth lvauthmodule
    LoadModule LVSnapshot lvsnapshotmodule
    LoadModule LVRFP lvrfpmodule
    LoadModule dir libdirModule
    LoadModule copy libcopyModule

    AddHandler LVAuthHandler
    AddHandler LVSnapshotHandler .snap
    AddHandler LVRFPHandler

    AddHandler dirHandler
    AddHandler copyHandler

    "CustomLog"$LVSERVER_ROOT/logs/access.log"'%%u %t \"%r\ hour' % > s %b.
    KeepAlive on
    KeepAliveTimeout 60
    Timeout 60

    As can side note, anyone tell me where the $LVSERVER_ROOT variable is configured?

    I tried the things:

    • Copy a new default configuration file before the entry into force
    • Writing a predefined file (encoded) before initializing config
    • Definition to root before initializing directory (it actually generates an error because the server is not active...)
    • Set WebServer.Active = TRUE several times inside the while loop
    • Toggle the web server in the ini file

    System:

    • LabVIEW 2010
    • PC with Windows 7 running

    Thanks for any help, because it makes me crazy slow!

    Ben

    Hi Marco, thanks for the reply.

    I have this guide was reviewed previously and had done all that he but a small section who gave me a hint of something to try and I have solved my problem, so thank you!

    If anyone is interested, here's the problem:

    The directive DocumentRoot folder in the config must exist or the Web server cannot be started. So basically, make sure that the file points to a folder that exists!

    This leaves two small annoying problems if - you can't see if the file exists (and then create it) before starting the Web server, because you can not query the path to the folder without the Web server running.

    AND

    You can't really define the configuration programmatically file as parameters from the file are responsible for execution, not on the start Web server.

    The result of this is that the config file and the folder root document should be created (and corresponding of course...) when the executable is built / installed on the system. Not a massive headache, but it means do not forget to put things in the build specification and do not rely on software to do the job at startup

  • Copying files from a web server to the VMFS data store

    Hi everyone I have a little trouble working it.

    I say a file on a Web server http://webserver/important.txt and I want to copy this file in a local data store.  I am able to copy the file from the Web server to the server I'm running PowerCLI, and then to the data store, but I can't work on how to copy directly.

    Any ideas?

    As far as I know, the Copy-DatastoreItem cannot handle this. The cmdlet requires a path to the Item parameter.

    You will need to first create a local file and then copy in the data store.

  • ASA5500 - anyconnect VPN not access Web server in DMZ

    Also have question access to management 0/0 (192.168.1.1) of the Interior of the E0/1 (192.168.2.0) network

    @richyanni1 ,

    For your VPN - DMZ problem, the following is the most likely cause of your problem:

    nat (inside,dmz) source static obj-dmz obj-dmz destination static obj-vpnpool obj-vpnpool
    You should have in place:
    nat (outside,dmz) source static obj-vpnpool obj-vpnpool static obj-dmz obj-dmz
    That's because VPN clients appear to come from the outside (to some purposes NAT) and the need to be exempt from NAT to access the resources of the DMZ. Management problems, the problem is asymmetric routing. When your packages arrive on the management UI, the ASA will try to send back traffic (starting with the 3-way TCP transfer protocol which will fail) through the inside interface but that won't work because ASA helped him, the source of the acknowledgement of receipt would SAA within the interface IP address, not the address of interface management in which the SYN sent. That's why most of the people have not historically used the management interface to ASA unless you have a real out-of-band network for management. Cisco recently introduced a separate fair management routing table, but you need to switch to 9.5 (1) or later to take advantage of that.
  • DMZ web server-&gt; inside the database server

    Suppose that a network topology looks like this:

    A PIX with 3 interfaces:

    interface (private public static IP 10.10.10.1)

    interface (public static IP of 69.110.38.35)

    interface (static IP private address of the 30.30.30.1)

    --------------------------------------------

    The internal network has a {server} with the IP address of 10.10.10.2.

    The DMZ has a {web server} with the IP address of 30.30.30.2.

    I will welcome external guests (outside) access to the web server (30.30.30.2) via port 80.

    This web server access turn the database server (10.10.10.2).

    Assume that all other commands are issued. Then, I'll create an access list that allows server WWW DMZ to communicate with inside the database server.

    access-list dmz-to-inside permit tcp host 30.30.30.2 host 10.10.10.2 eq 1521

    Should I publish the following, too:

    (1) access-list dmz permit tcp host 30.30.30.2 no matter what 80 eq

    (2) access-group in interface dmz dmz

    (3) static (inside the dmz) 10.10.10.0 10.10.10.0 netmask 255.255.255.0

    xlate clear 4)

    If so, what each of them do?

    Thank you for helping.

    Scott

    1. Yes, the static statement "10.10.10.0 static (inside, dmz) 10.10.10.0 netmask 255.255.255.0" will disable NAT. Although it is not necessary to disable nat, however, it saves money and simple to manage. the reason for this is the traffic between the dmz and inside is private, there is therefore not necessary to apply the public ip address.

    2 pix receives the package intended to 30.30.30.2 10.10.10.2. PIX examines the static statement and based on the static above statement, pix will not nat package (i.e. pix will leave the soruce address be) and send it to 30.30.30.2 via the interface of the demilitarized zone.

    for example

    original package - source 10.10.10.2, destination 30.30.30.2

    After pix - source 10.10.10.2, destination 30.30.30.2

    3. the "Clear xlate" command must be issued whenever the nat/global or static has been added/deleted/modified. This command is to force the pix to clear the existing ip translation.

    for example, before you add the command "static 1.1.1.1 (indoor, outdoor) 192.168.1.100 netmask 255.255.255.255", the pix may already have an ip 192.168.1.100 translation (it might come from the nat/global). now, after you apply the static command, the pix will keep the existing translation for a certain period time. 'clear xlate' is needed to erase the old translation and so to activate the new static statement.

  • Cannot access the Web server in the DMZ from the inside using IP global

    Hi all

    I hope it's a very simple question.

    I'm running a PIX 515 firewall v6.3. I set up a Web server in my DMZ and use static NAT for re-branded it overall static IP address. Access from the outside of the demilitarized zone works remarkably well. I can access inside the interface Web site using the internal IP, but I can't access it from inside interface using the global IP are entrusted to him.

    Is there a particular reason why this would not be allowed? My feeling was that the request would be forwarded via the external interface (as it is a global IP address) and then be bounced back by my sense of the ISP the request would come to the new external interface (as the static NAT is applied to the external interface).

    However if I try and access the global IP from my inside interface, then the browser can not find the server.

    can someone explain why this is so? Any information would be appreciated.

    see you soon,

    Wayne

    Code v6 pix or less don't let you have traffic "back" or return flow via the same interface on which it was sent. Having also your bounce back off of an external server traffic is never a good idea, because you won't be able to distinguish which and rogue attacks by spoofing someone outside your network.

    Since you are using pix 6.3 code, you may be able to outside the NAT. Add this static to your config:

    static (dmz, upside down) 203.169.113.110 10.1.1.27 netmask 255.255.255.255 0 0

    You may need to run a clear xlate after adding the new static statement. Note that the interfaces: it's demilitarized zone, inside inside, dmz.

    I would like to know if it works.

  • Another discussion to see a comments from the host Web server

    Howdy,

    I ran into something really puzzled. I have windows 7 host machine and two VM. Ubuntu 11.04 is one the other is RHEL7. The fundamental problem is that, since my host machine, I see an Ubuntu apache server and I do not see the server apache RHEL5.8.

    Details. I'm running 8.04 vmware and have reinstalled vmware-tools on every machine after the upgrade. I'm running an internal NAT. The host IP is 192.168.2.1. The Ubuntu IP is 192.168.2.128. RHEL 192.168.2.129. The problem is between the host and the 192.168.2.129 box of RHEL. What's weird, is that I do not see my server apache RHEL host, but of the terminals on both boxes, I can ping another machine by IP address and since I edit/etc/hosts(buried in c:\windows\system32\drivers) I can ping between host and guest by the url "myapp.local" as well. The period of INVESTIGATION were determined by ipconfig and ifconfig on the host and the guest respectively. I watched netstat on the client and do not seem to have anything httpd listens on port 80 on the guest. I'm really at a loss. The Ubuntu box configured the same way works, but the RHEL box fails.

    I don't know if I listed everything that could be of use here, but if someone could chime in with ideas I would appreciate it. In brief

    (1) ifconfig shows URL

    (2) pings may be

    (3) dns is defined in/etc/hosts

    (4) proxy ignore is set in firefox on the host and the proxy reviews configuration to avoid transmission by proxy problems

    (5) web page expires, the server is invisible

    (6) newspapers on the comment server don't watch not demand of the host being considered.

    Thank you

    Danny

    Based on what you said in the OP I would say that you need to properly configure your firewall on the client to allow WWW (HTTP).  If not that something is still not set up correctly and very probably not really a question of VMware.

  • How to separate the application server and web server on the level of physical servers?

    I want to separate the application server and web server: locate on different hosts. Generally, we use Weblogic ACE. In the future maybe use Apache Tomcat as web server.
    Example,
    192.168.1.10 - as - Weblogic application server / module EJB
    192.168.1.11 - as a Web server - Weblogic / WEB module (can be - Apache Tomcat)

    Impossible to find examples and resources about it on google.
    Thank you.

    So, if we're looking for a subject such as:

    try {
        someEJB = context.lookup("ejb/Videotheek#model.logic.Videotheek");
    } catch (NamingException e) {
        e.printStackTrace();
    }
    

    If the EJB application is clustered in an object of type ' ClusterableRemoteRef (-4005477377232786958S: 172.31.0.107: [7003,7003,-1,-1,-1,-1,-1]: [8351443287261246917S:172.31.0.107:[7002,7002,-1,-1,-1,-1,-1]:ScriptDomain:VideotheekServer1/292])/289 172.31.0.107:ScriptDomain:VideotheekServer2 - 4005477377232786958S:172.31.0.107:[7003,7003,-1,-1,-1,-1,-1]:172.31.0.107:ScriptDomain:VideotheekServer2/289,-' is returned, which is part of the wlfullclient.jar.)

    You can try using the EJB or the annotation of the resource (do not know with certainty if Tomcat is favorable). For annotations work, you must use version servlet 2.5 or later. JNDI research work in a general such as for example Tomcat servlet container.

    I publish a quiz in Captivate as HTML5 and host it on a Web site. I would like to know how I can move my site to the HTML5 based Captivate quiz data.

    So far, I have had success are given on captivate by having the file POST the results of a quiz finished in a RESTful way. However, I have not had success put data in the file. I would like to transmit information such as the user ID and the ID of the quiz, maybe same position current slide so that I can match quiz information to my database. I'm not specifically looking for a solution to the user ID, ID quiz, etc. because I can be creative, in this regard, I just want to know if others have been able to define variables when the Captivate file loading.

    I tried a definition of the variables in two ways:

    -Declare the variables with javascript, ajax, load the page in a div. Because of the problems of dependence from the captivate file uses relative paths to the assets folder.

    -Change the published html file by adding the javascript variables, this returns an error message saying that I can't replace the existing captivate variable

    -Add js variables in the init function, this has no effect.

    Simply pass the username and id I used the following.

    Note that the URL contains query string parameters that correspond to variables in captivate

    http://mywebsite/course/index.html?cpQuizInfoStudentID=IDHere&cpQuizInfoStudentName=Studen tNameHere

    Another way to use JavaScript to read the query string and the variable of the entitlement in CP for query string values. I remember reading some more detail, but can't remember where.

  • Web server and the apex running on the same machine - possible conflict port 8080

    Hi guys,.

    I installed Apache Tomcat and currently in the process of installing Oracle 11 G in the same machine.

    The tomcat uses port 8080 and I understand other installs, the APEX uses 8080 as well.

    Is there way after installing Oracle 11 G database XE, stop APEX so it is not in conflict with the use of 8080 Tomcat? I have no use for APEX at this point you want to stop if possible.

    Alternatively, it can be configured to use a different port?

    Thank you very much.

    You can do either, stop it or change the port. So sad that you said that you «have no use for Apex...» ».  :(

    What gateway do you use for Apex? What is the EPG, OSH or the listener of the Apex? If you use the EPG, there is an order any structure/API for it. Here are a couple that you can run a SQLPlus session:

    SELECT DBMS_XDB.GETHTTPPORT FROM DUAL;
    
    EXEC DBMS_XDB.SETHTTPPORT(port);
    For example:
    
    EXEC DBMS_XDB.SETHTTPPORT(8080);
    
    OR
    
    EXEC DBMS_XDB.SETHTTPPORT(8181);
    

    If you use OSH then you go to your OHS/Apache Directory and find the path to the OPM and issue commands to start where your stop. If it's the listener of the Apex with Glassfish, then you go to the console of administration of Glassfish and stop your deployment of Apex from there. I'll leave you the specifications.
