Port open but no access.

Dear All,
I have created a simple listener program listening on port 9000. So when I do netstat -a I can see the port is listening. I have gone to my router and forwarded that port to my pc. Then in the windows firewall I have added the exception as this port. So when I go to this website http://www.canyouseeme.org/ and put my port as 9000 I can not see my port is opened. What else must I do for my listner to listen externally. Thank you.

The problem I cannot give the external IP as I am using a home line so it is Dynamic(DHCP). As a note either your home router has an IP that is visible to the internet or it doesn't.
If it doesn't then it is because your ISP, not you, is doing it that way.
And nothing you do will change that.
And that site you cited does not change that. It reports the public termination IP that it sees. It will report that for any browser because any browser that gets to that site must be using a route that includes a public IP. Which is not the same as saying that it is your router's IP.To add to that a bit...
If you go into your router's configuration, you should find something like "LAN Address" and "WAN Address". If the WAN Address (or its equivalent) matches the IP that the service shows you, then your router is publicly visible. If not, it is not, and you're out of luck, unless you can convince your ISP to change something for you. If your router is publicly visible, and if you have set up port forwarding correctly, and if you have a server listening on the appropriate port on your computer, AND if your ISP allows connections to be opened to your router (which it may or may not do, even if the router has a public IP address), then, and only then, you will be able to connect to your server on your PC from the internet.
If you cannot connect, then at least one of the following is true:
1. Your router does not have a public IP address.
2. Your ISP does not allow incoming connections to your router's public IP address.
3. You have not correctly set up port forwarding.
4. You do not have a server running on the port and IP to which you are forwarding.
5. You are not attempting to connect to the port and IP from which you are forwarding.

  • Windows Firewall has a port open but when I do a port scan the port is closed

    Hello,
    I have a new door entry device that is being installed that has a internal IP address of say 192.168.200.12 that requires port 3001 to be open. The device is reachable via ping and is plugged into a HP Procurve 2910al switch that is connected or supposed
    to be connected to the the server for the KeyScan software at 192.168.200.13 but even with the TCP/UDP ports opened up on port 3001 the server at 200.13 it can't communicate with the device at 200.12 on the required port of 3001.
    Ironically I ran Zenmap to see if the port was open and it's not even registering the port as being open.
    I'm doubtful it's our Sonicwalls since this is a internal address; we are running a 32 server Windows Server 2008 R2 network that is running perfectly fine.
    What could I do to allow this device to communicate with the server even if the firewall is disabled or has holes poked into it?

    The vendor that was here to install it (CCTV) said that port 3001 needs to be open in order for the key-entry program on the server (a normal Windows 7 fat client) to communicate with the device in question @ 192.168.200.12.
    In my experience for Windows all you would need to do is either disable the windows firewall or poke a hole in the firewall for TCP/UDP on port 3001 for this to work.
    We run a network of purely on HP Procurve switches (that functions perfectly fine for over 1200+ user network) so were not dealing with a Cisco switching security issue so I'm left to think outside of the box or in this sense inside of the box. I'm doubtful
    it's our network but then again I've never had to open a port for a device that you can't physically manage.
    The device in question as stated before is like the hub that all of the key-entry scanners from all 150 doors tied into that then communicates via the IP in question to the key-entry server. in theory it should be simple but lol nothing ever goes smoothly!!!!
    any ideas?

  • All ports open, but still no luck over the internet

    I have ARD 3.1, the computer I am trying to connect to has client 3.1. Both computers are on DSL connections behind routers with the software and hardware firewalls turned OFF (temporarily for testing!). Port forwarding is on, and is pointing to the correct local NAT ip.
    Yet, whilst ARD is correctly giving me the DNS name when I tap in the IP, it wont recognise any recognisable ARD clients the other end, let alone actually connect to anything.
    Any ideas beyond "your firewall isnt off, or port forwarding isnt set up correctly"?
    Thanks

    I always use this handy web page to tell me if ports are open, this must be done on the machine that is running the service, ie the remote machine-
    http://canyouseeme.org/
    Enter port 5900 and click check, this will tell you if port 5900 (ARD) can be seen by web page
    If it comes back with an error then there is a problem with either your config or your ISP has blocked that port.
    Have you tried ssh access?
    It runs on port 22 and is a good way to tell if you have various settings correct. Open port 22 to remote machine and in terminal type -
    ssh -l username xxx.xxx.xxx.xxx
    Change username to valid user on remote machine and the xxx should be the IP of the router of the dns name.

  • Firewall port open but not accessible

    Hi Folks,
    I am trying to open port 587 in OSX server 10.3.9. I've gone to 'Firewall --> Settings --> Advanced', clicked on the 'add' key and set up a new port as follows:
    Action: allow
    Protocol: tcp
    Service: other
    Source Address: any; Port: 587
    Desintation Address: any; Port 587
    Interface: other
    Doing this will NOT result in port 587 opening. I know it's not open because if I turn the firewall service 'OFF', I can access that port. However, with the service 'ON', I can't get through.
    Any help would be most appreciated.
    Regards,
    Luke

    Your rule is too specific.
    You're telling the firewall to allow traffic that is coming from port 587 on the remote machine to port 587 on your machine.
    AFP connections only use a destination port of 587. The source port could be any available port number on the remote system, and would probably never be less than 1024.
    Change the rule so that 'Source address' is 'any' and you should be fine.

  • Iphoto opens but cant access it

    When i click on iphoto it does not appear on my screen. If i hit F3 to bring up all of the open tiles it is there but if i try to click it it disappears, it looks like it slides down into the dock. i can see the 'welcome to iphoto 09 window that i usually just close and i can see the library behind it.

    A good general step for strange issues is to renew the iPhoto preference file - quit iPhoto and go to "your user name" ==> library ==> preferences ==> com.apple.iPhoto.plist and trash it - launch iPhoto which creates a fresh new default preference file and reset any personal preferences you have changed and if you have moved the iPhoto library repoint to it. This may help
    This does not affect your photos or any database information (keywords, faces, places, ratings, etc) in any way - they are stored in the iPhoto library - the iPhoto preference file simply controls how iPhoto works - which is why renewing it is a good first step.

  • HT203175 I have one laptop that itunes will open but will not connect to the iTunes store

    I have a laptop that itunes will open but never accesses the store.  I have verified that there are no viruses and the internet connection is excelent.  I have been through several of the troubleshooting tips on the web sitebut no luck.  So I cannot deautherize that laptop since I am at my limit of 5 computers under one account which I think is crap since 2 of the computers died and I can never deautherize them ever! 
    I have another computer that I am trying to deautherize but it doesnot recognize my username and password for some reason eventhough it is working.
    All of this just so I can update my **** software version on my 5th iPhone.
    Please help if there is anyone outhere....

    I have a laptop that itunes will open but never accesses the store.
    Doublechecking ... it just keeps saying "Accessing iTunes Store"? Or is something different going on?

  • HT201412 My i Pad 3 shows "cannot Access Find My Friends open the app and review your sign in information to continue sharing your location. And I have two buttons : Later and Open but they don't work, As long as I have this situation I can do nothing on

    My i Pad 3 shows "cannot Access Find My Friends open the app and review your sign in information to continue sharing your location. And I have two buttons : Later and Open but they don't work. As long as I have this screen situation, I cann't do anything on my I Pad. Please help !!

    I have the same problem on my iPhone4. It is obviously a bug in the software. Once it pops out I am locked out of my phone. I can't even begin to describe the frustration this causes. All that stuff about holding down the buttons is useless. the phone won't even shut off. I can take a screen shot like that or go to voice control. Even when I got to a wifi connection, I can't get on. This app blocks everything else. This is a serious bug and can have serious consequences. The only thing my phone would do is go to voice control and let me play iTunes or phone people. Some smart phone hey?
    I have finally got to a place with a wide enough wifi to connect my computer and restore the phone. This has lasted over a day!
    I don't even know why Find My Friends is on my phone. Is it part of the package and how do I turn it off?

  • IPhoto opens but then the spinning rainbow wheel appears and I can't do anything. I have opend iPhoto with the Option key pressed and rebuilt the library and it still happens.  I want to at least access my photos and copy them to an external drive.

    iPhoto opens but then the spinning rainbow wheel appears and I can't do anything. I have opend iPhoto with the Option key pressed and rebuilt the library and it still happens.  I want to at least access my photos and copy them to an external drive. Anyone have ideas on how to get to them?

    Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
    1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
         User/Home()/Library/ Preferences folder.
    2 - delete iPhoto's cache file, Cache.db, that is located in your
         User/Home()/Library/Caches/com.apple.iPhoto folder. 
    Click to view full size
    3 - launch iPhoto and try again.
    NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.

    You can only add music to iTunes Match from your iTunes library on your computer, not from your iOS device.  If you have music on your iPad that is not on your computer, you'll have to import it to your iTunes library on your computer to add it to iTunes Match. 
    Music purchased from the iTunes store can be imported directly to your iTunes library by authorizing your computer for the Apple ID(s) used to purchase the music (in Store>Authorize This Computer), then connecting the iPad to your computer, opening iTunes and going to File>Devices>Transfer Purchases.  Music from other sources will require using 3rd party software to transfer to your computer, such as Touch Copy.

    Changing body text is not simple. It's a desperate last resort. You need to buy the exact font. Acrobat will not let you edit in a font you don't own. Even then, it's undertain. Consider preparing an overlay in InDesign.

    If you have 2-step verification set up for your gmail account, you will need to generate an application-specific password for your iphone applications (because those apps apparently don't support 2-step verification).
    Go into your google account, look in accounts/security/2-step verification, there is a link called "Manage your application specific passwords"   Use that to generate a special password for your iphone apps and use that instead of your usual gmail password on your phone.

  • Fire is loaded, it opens but it will not max. Can not access.

    I've spent my day trying to get Fire Fox to start working again. I've deleted and reinstalled several times and have tried to work through web answers.
    At this point, the computer window7 Task Manager indicates that Firefox is open. The icon on the task bar shows it to be open but when the icon is clicked it does not maximize it appears to jumps off the screen.
    Is my answer to this problem is to use another browser? I'd support Fire fox but it has to work and be easy.
    Hopefully you have an easy fix for a fire fox user.

    Hello,
    If you right click on your task bar, you can select "Show Windows Stacked" or "Show Windows Side by Side" if for some reason windows are appearing off of your screen. Alternatively, if this occurred after installing an extension, '''try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
    If Firefox is not running (close it from your task manager if it is), you can start Firefox in Safe Mode as follows:
    * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br>
    [[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
    ''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    When you figure out what's causing your issues, please let us know. It might help others with the same problem.
