To host an web server behind an firewall which is behind an router

Dear All,
Now i am trying to find an solution for this network structure
Aim: To host an webserver
Products used : HP Blade Server, Cisco 2960 Switch, Cisco ASA Firewall 5500, Cisco Router 1900 
Connectivity : Static ip with Leased line from one ISP (8 IP's with 6 usable)
Setup: Server -->Switch-->Firewall-->Router-->ISP-----------ISP-->Router-->User
Server : 192.168.20.10/24
Switch : 192.168.20.2/24
Firewall : 192.168.10.2/24 (router end) and 192.168.20.1/24(switch end)
Router : 192.168.10.1/24 (firewall end) and 11.11.11.12(serial) (WAN IP)
Default gateway for Router : 11.11.11.11 (Wan ip gateway)
Usable public LAN  ip : 20.12.1.1-20.12.1.8
Like to host the server using one of the public lan ip natted with the server
If anyone know how to configure this kindly give ur suggestion and configuration details..
I have only one week time to do this..

  • Setting apache as a front end host-proxy web server for weblogic 10.3.3

    Hi ,
    i have installed apache 2.2.21 in the red hat linux 6 environment.Now i am trying to set that apache web server as a front end host ,proxy web server for my weblogic 10.3 application server cluster. My apache is listening to the port 8080.
    What changes i had to made in admin console of my server as well as in the httpd.conf file of apache.
    Can any one guide me how to proceed ?
    Any help is highly appreciated......

    Thanks Ravi,
    i have already gone through http://docs.oracle.com/cd/E12840_01/wls/docs103/plugins/apache.html.
    In my case "mod_wl_22.so" was not available but i downloaded this p10051826_1033_Generic.zip file from where i got that file and make it available in the modules directory, changed the file permissions (using chmod 755 mod_wl_22.so) and also changed the httpd.conf file as below :
    LoadModule weblogic_module modules/mod_wl_22.so
    <IfModule mod_weblogic.c>
    WebLogicCluster wlserv1:7001,wlserv2.com:7001
    MatchExpression *.jsp
    </IfModule>
    By using /bin/ls command i checked the following :
    /bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
    Using file mod_wl_22.so i checked the following:
    mod_wl_22.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped
    My problem is when i used ./apachectl -t i got the following error :
    httpd: Syntax error on line 112 of /u40/app/apache/conf/httpd.conf:
    Cannot load /u40/app/apache/modules/mod_wl_22.so into server: libstdc++.so.5:
    cannot open shared object file: No such file or directory
    So can u please guide me where my problem is and how to rectify it ? Its urgent. please help me.
    Thanks

  • Connection from the web server to the database which is situated in another machine.

    Thanks for the reply.
    I need to know, whether there shold be a physical connection between the web server and database machine? or can we connect to the database machine through the web, if the database machine has a domain name? if there is a physical connection, we can use the jdbc/odbc connection. but if we are connecting through the web, how can I estblish the connection using a JDBC/ ODBC connection?
    Regards,
    George

    As long as there's a network connection between the two machines, you should be able to make the connection. I'm not sure what the difference between a 'direct connection' and a 'connection through the web' is-- are you actually running a network cable from one machine to another?
    When you cannot make the connection, are you able to do a 'tnsping' on the target database?
    When you say 'connecting through the web', is it possible that you're going through a firewall? If so, the firewall may be blocking the ports you need to communicate on.

    Solution, give me your number so we can talk about or setup captures on the ASA to confirm that traffic from the Internet is being routed correctly to the ASA and also review logs.
    capture out interface outside match ip any host 78.93.232.66
    capture in interface inside match ip any host  10.10.10.4
    After you try to access the server via the public IP from an Internet client check the captures:
    show capture
    If you see packets in the capture, download them:
    https://10.15.1.1/capture/in/pcap
    https://10.15.1.1/capture/out/pcap
    It will ask you for your credentials to be able to download the file.
    Check logs via ASDM:
    Log into ASDM > Monitoring > logging > Real Time log viewer
    Type in the external IP address of the server and run another test, if you see logs post them

  • Issues with accessing forms applications behind a firewall & caching proxy

    We have web enabled an forms application and has the following set-up at server end.
    Machine no 1. Oracle Forms Server 6i with patch level 1 listening on HTTP/Port 80 on a windows NT box.
    Machine no 2. Apache Webserver. listening on HTTP/Port 80
    Both the machines are behind a firewall which allows only HTTP on port 80.
    At clients end we have
    1. a firewall which allows only HTTP on port 80.
    2. a caching proxy server
    The client machine connects through the caching proxy server.
    When the client connects the applet gets downloaded and initialised, the form server log shows the following
    -Forms Server Log-----
    [09/27/00 15:01:09 India Standard Time]::LISTN: Connection Request [ConnId=13, Addr=194.120.163.251:16278]

    at the same time at the client side we get a FRM-92050 error: Failed to connect to server fs.formserver.com:80
    Please help
    Thanks

    Thanks Henrique.
    This is not very promising but it confirms there is a potential issue
    How did you manage to solve the problem, allowing the NW server/application to perform direct accesses?

  • Can anyone help me know the difference b/w application and web server?

    i tried reading about application and web servers. it appears to me to be the same. please do help me to differentiate. Thanks :-)

    An application server hosts business logic components for an application. A web server is an application which accepts HTTP requests.
    An application server may come packaged with a web server.
    A web server is a very simple process. It's HTTP daemon process that listens for incoming requests over HTTP protocol on a specified port usually, 80. For simple, static web pages the web server has the built in logic to serve them but for a complex operation(say read from database and display some records), it routes the URL to a component like the servlet engine....
    An application server is a much broader term. For example the servlet may need to invoke certain business logic components like beans or activex dlls. The server that hosts these components is the application server.
    Hope you are clear now.

  • USB Pass-Through From Windows 8.1 Host To Windows Server 2012 R2 VM

    I want to be able to connect with a Windows Mobile Device through Windows Mobile Device Center, within a Virtual Machine.  When connecting through the Hyper-V Manager and through Remote Desktop, under "Other supported RemoteFX USB devices",
    I can see the Symbol USB Sync Cradle.  In the VM, in Device Manager, I don't see a USB connection.  In the VM, I don't see any meaningful errors in the Event Viewer.
    Host:  Windows 8.1 Enterprise Hyper-V on a Domain.  Upgraded from Windows 8.1 Pro.  When this computer was originally installed with Windows 8 Pro, Hyper-V was enabled.  I removed Hyper-V, and installed VMWare Player, because I wanted
    USB Pass-through.  I then uninstalled VMWare and installed VirtualBox.  Recently, I uninstalled VirtualBox, upgraded to Windows 8.1 Enterprise, and enabled Hyper-V.
    Virtual Machine OS: Windows Server 2012 R2 on a Workgroup.  Started out with being a VMWare VM, using VMWare Player.  Moved to VirtualBox.  USB Pass-through was working in both those virtual environments.  Used Disk2VHD to convert the
    VM to a VHDX file.
    On the Host:
    Windows Mobile Device Center is connected to a Motorola Windows Mobile Device (MC959X) sitting in a Symbol USB Cradle.  The OS on the scanner is Windows Embedded Handheld 6.5 Classic CE OS 5.2.29217 (Build 29217.5.3.12.26).  Advanced Networking
    (USB to PC) is not enabled.
    Enabled RemoteFX. 
    In the RDP file, and in the Registry, added the GUID's for:
    WPD "{eec5ad98-8080-425f-922a-dabf3de3f69a}";
    Windows Mobile "{6AC27878-A6FA-4155-BA85-F98F491D4F33}";
    USB Device "{88BAE032-5A81-49f0-BC3D-A4FF138216D6}";
    Windows CE USB Device "{25dbce51-6c8f-4a72-8a6d-b54c2b4fc835}";
    GUID_DEVINTERFACE_USB_DEVICE "{A5DCBF10-6530-11D2-901F-00C04FB951ED}"
    Ran "sfc /scannow"
    All Microsoft Updates are current.
    What am I missing?

    I hope it's something like that. Those features have been installed.  Here's what PowerShell shows is installed:

  • Add Web content into ISE Web Server?

    Hello,
    We use Cisco ISE 1.2.0.899 on our network.
    We would like to add a Web based documentation about Guest Portal ("how to find MAC Address", "how to release/renew IP Address"...) on our network to help users.
    Idealy we would like to host these data on the Web server integrated to ISE (which already hosts Guest/Sponsor Portals).
    Does ISE allow that?
    Unregistered users (or not already profiled devices) are automatically redirected to the Guest Portal, but we would like they're able to access to this documentation (hosted on ISE Web Server or another Web Server).
    How can we set that? By not using port 80 to access to this documentation?
    Which elements does ISE identify to redirect browsers to the Guest Portal? Is it port 80, http protocol or other?
    Regards,
    Chris

    Thanks Marvin.
    I've checked this guide, I may have misunderstood, but I've seen how to customize built-in content only, and not how to add our own content.
    We've created our own documentation (html files), and we would like that our users can access to it when they are using the Guest Portal.
    We thought add the documentation URL on the "Guest Portal Login", to open it in a pop-up or new window.
    Can we host these documentation files on ISE Web Server (apache)?
    Or do we have to host them on a separate server?
    Because unregistered users/devices are automatically redirected to the Guest Portal, we would like to know how to allow users to access to this online documentation without the documentation pages are also redirected to the Guest Portal?
    Thanks for your help,
    Chris

  • Virtual hosting on leopard server

    Hello,
    I have a leopard server on which I want to have two sites served from the same ip address port combination.
    I am using the Server Admin tool bundled with OSX server to configure Apache.
    I have created two sites in Sites tab. One has the name "mydomain.org" and the other has the name "machinename".
    They are both configured to serve from the same local IP address.
    The name "mydomain.org" is served by DNS and the name "machinename" is configured on the client's /etc/hosts file.
    From what I know of virtual hosting, the web server receives a http header called 'Host' with the host name that was used on the browser, to select the files to serve. I have sniffed the http network packets from my client machine to the web server and seen this header set correctly to the hostname used on the browser.
    The problem is that just one site is being served to both names. I want to select the site according to name.
    What can I be doing wrong ?

    Done it the hard way.

  • Mobile Web Server installation failure

    Hi Forum,
    I have used the server on my phone previously. It worked well.
    Now after a updating my phone, I cannot even install the application. It runs through the installtion and then starts a "installing web server" half way through which it fails!
    Despite installation failure it features in my App Manager but not in 'My Own' folder. I uninstall it and reinstall to no avail.
    I am a Nokia N93 user.
    Would greatly appreciate assistance as I want to demo the software for my class.
    Best,
    wirefree

    I had exactly the same problem ("Installation failed" at install time) but finally got it running.
    My steps:
    0. I removed the unfinished installation of the MWS.
    1. I manually installed the Open-C libs (only glib.sis, pips_nokia_1_3_SS.sis and ssl.sis) from the SDK here: http://www.forum.nokia.com/main/resources/technologies/openc_cpp/
    2. Then I manually installed python (PythonScriptShell_1_4_4_3rdEd.sis) from here: http://sourceforge.net/project/showfiles.php?group_id=154155&package_id=171153&release_id=609802
    3. Finally I reinstalled the mobile web server (v1.4 beta) . No error message anymore. Everything works like a charm now. Hope this helps. :-)
    Kind regards,

  • NAT/PAT Setup with internal web server.

    Environment:
    Web Server inside and 10 internal workstations.
    One external public IP address.
    Cisco Router 806 with HTTP server enable.
    Conditions:
    External users have to be able to access the web server.
    The internal users have to be able to access the web server via the "EXTERNAL" IP address. Since they are using an external DNS.
    Scenario:
    The internal workstation request from external DNS address for the web server.
    DNS replies with external IP address.
    Workstation attempts to connect to web server via external IP address.
    Connection fails at the router showing the router's HTTP logon page.
    We are trying to implement NAT/PAT inside, with static assignment to port 80 to the internal web server.
    Thanks, Pat Askins.

    You need to use cisco NAT virtual interface,
    Example:
    your internal network web server ip 192.168.1.10/24 Fa0 router Fa1 Public Ip address 1.1.1.1
    here is what you need to configure in NAT router to resolve your issue:
    int fa0
    ip nat enable
    no ip redirects
    int fa 1
    ip nat enable
    no ip redirects
    ip nat source static tcp 192.168.1.10 80 1.1.1.1 80 overload
    ip nat source list 1 interface fa0 overload
    access-list 1 permit 192.168.1.0 0.0.0.255
    now you can try access to your 1.1.1.1:80 from inside network.

  • G web server

    Hello,
    I have an application made in Labview7.1, that should be remotely controled. Also it must be protected with user name and passwords. For that I used G web server from Internet toolkit ver.6.0. I followed the instructions for password protecting the web pages, so the G web server is sharing the same port as the Labview web server, and when I run the VI from Labview enviroment it works fine. But when I build the application, the G web server is returning the error 60, the port is already used by anaother application, that application beeing the Labview web server from the app. How can I get around this?

    Can't you use the G Web Server to both give you remote control and security? I've linked a thorough discussion of using the HTTP Web Server with an executable, which also has links to some additional information on this topic. The discussion even specifically mentions not being able to use both servers on the same port, so you should really switch entirely to the HTTP web server to get both remote control and security. If you can't get things working, feel free post a small example that illustrates your dilemma.

  • Installing Iplanet web server and directory server behind a firewall

    When installing iplanet web server and directory server behind a firewall - should the interal ip address be used or the external ip address?

    Hello,
    When you are installing iplanet web server behind a firewall,you should use the internal ip address in the firewall.
    1. The external ip address connection to the Internet. The type of IP address used?dynamic (commonly used for standard
    modems) or static (commonly used for cable modems) is dictated by the ISP to which you connect and the type of service it provides.
    2. The internal ip adress connection. This connection must be a static IP assignment, and it must be assigned by you.
    obviously it depends on the type of firewall setup you have.
    Thanks

  • Web server and Exchange behind an ADSL router

    Hi all:
    I finally was able to go through the basic configuration of my new cisco ASA 5515 X (i'm completely new to cisco devices). 
    I also managed to create VPN's to my two Amazon VPC sites. This was particularly hard because my ADSL Router which this Cisco firewall is behind was making trouble.
    Finally, all I had to do is reboot the ADSL Router and it all started working, but I had a hard time to find out the source of the problem (the guys at Amazon did the job, to be honest)
    Now I face the next step, opening my web server and exchange server to the world. How is this done? Do I need to do something special because of the ADSL router?
    Thank you.

    On the ASA you'd do this with an ACL
    object-group service EXCHANGE_SERVICES tcp
     port-object ew www
     port-object eq imap
    ...etc etc
    access-list outside_in extended permit tcp any host 192.168.203.24 eq www
    access-list outside_in extended permit tcp and host 192.168.203.11 object-group EXCHANGE_SERVICES
    access-group outside_in in interface outside
    You'd also have to allow access in from your ADSL router.

  • Access websites hosted on local web server

    Hi there,
    I have a Cisco ASA 5505 in my home office which has a few PCs behind it with a linux web server running some websites. I can access the websites from outside no problem (i.e. on my iPhone using a 3G connection). However, I struggle to access the websites from within the network. The ASA gives me this error:
    6
    May 05 2013
    11:52:27
    192.168.55.61
    50420
    Failed to locate egress interface for TCP from inside:192.168.55.61/50420 to 86.*.*.*/80
    ASA runs version 9. Here is the config bit:
    object network denon-server
    host 192.168.55.200
    access-list outside_access_in extended permit tcp any object denon-server eq www
    object network denon-server
    nat (any,outside) static interface service tcp www www
    Any suggestions?

    Hi,
    I assume that you are trying to reach the LAN server with the public IP address that the ASA holds and also uses for the above Port Forward / Static PAT configuration?
    If this is the situation then I am afraid that with the current configuration that is not possible. The NAT configuration towards Internet is done between probably "inside" and "outside". So "outside" interface holds the public IP address. ASA doesnt let you connect to that "outside" IP address from behind the "inside" IP address. (Or any other interface for that matter)
    What you could try to do is configure a NAT that would enable you to use the public IP address of the server even when connecting from the "inside" of ASA.
    Try this
    object network SERVER-LOCAL
    host 192.168.55.200
    object network SERVER-PUBLIC
    host 86.x.x.x
    object network LAN
    subnet 192.168.55.0 255.255.255.0
    nat (inside,inside) source dynamic LAN interface destination static SERVER-PUBLIC SERVER-LOCAL
    Where
    SERVER-LOCAL = Is the "object" that defines the real IP address of the server
    SERVER-PUBLIC = Is the "object" that defines the public IP address of the server (that ASA holds on its "outside")
    LAN = Is the "object" that defines the subnet from where LAN users connect to the server public IP address
    Check that the network mask is correct for the LAN and fill in the public IP address.
    The actual NAT configuration tells the ASA this
    When a connection from LAN is coming towards SERVER-PUBLIC then UN-NAT SERVER-PUBLIC to SERVER-LOCAL and NAT LAN to "inside" interface IP address (as defined by the parameter "interface" in the configuration)
    This should enable the LAN hosts to use the public IP address to connect to the server. The server though will see the connections coming from the ASA "inside" interface IP address.
    Hope this helps
