Port forwarding only works for BT customers..

Hi, I have a little bit of a strange issue and i'm hoping somebody could help.
What I have is various devices NAS/IPcam/VNC etc, previously I had ports forwarded to these devices and all was working ok, i could reach them via the WAN address.
What I have currently is that the WAN address my router tells me I have is a 100. address and sites such as whatismyip.com tell me the 81. address (im not sure if this is normal but I think it is?).
The problem I have is that port forwarding now only seems to work if i try and connect to my devices from BT connection using the 100. address. The 81. address is unreachable from BT or other ISP's and sites that check for open ports tell me the ports are closed. I have tried several routers as i initially thought it was an issue with my router but they all give the same problem.
Not sure if any more information would be required but from the testing ive done it doesnt seem like a issue with my router. Any ideas? CAn provide more info if needed, just ask.

If you enter the IP address on this page http://www.whatismyip.com/ip-tools/ip-whois-lookup/
you can see who it belongs to.
But I suspect that its something within your router that is returning the wrong WAN address. Do you have an ADSL connection, or an Infinity connection?
Yo may have difficulty connecting to your own external WAN address from within your own network, unless your router has NAT loopback enabled.

  • WRV210 port forwarding only works on http!!!

    I'm trying to use SSH port forwarding, and VNC on the future.
    Right now the only one that is working is http. I have enable both HTTP and SSH over two different PCs, and only the http one is working.
    We already have version 2.0.0.11. Also tried DMZ the second PC and didn't work.
    I hear about to use DHCP, and then I defined the second PC mac on the table, and still didn't worked.
    Any idea of what is going on with this equipment.

  • Port forwarding not working for VPN

    Hi there,
    I am at a loss as to what I am doing wrong with regards to setting up a VPN. I admit this is all completely new territory for me, and I am learning as I go along, so may have overlooked something very obvious.
    I have openned up the VPN ports on the router (500, 1701, 4500 - UDP; 1723 - TCP), and can confirm from the logs that they are letting traffic in ok.
    So that leaves the server itself - testing using an open port checking tool confirms all ports I have open in the router firewall, and active and accessible on the server, except the VPN ports and service, are indeed open and accessible.
    The VPN service is running, and I have ensured the services are available within the firewall service for 'all', and all services available for the 192.168.1.xxx range.
    I have indicated that the VPN should use the range - 10.0.0.1 to 200
    The DNS and DHCP services on the server are running. At the domain resgitsrar, I have indicated that the subdomain I am using to access the server and its services via the web should point to the static IP I have from the ISP.
    I should mention that if I use the local IP address of the server, I can connect ok, it is only when I use the static IP that I am unable to connect.
    Every other port opens up successfully - FTP (21), Web (80/443), etc - just not the ones for the VPN, so I assume there is some sort of conflict between or within the the VPN/DHCP/DNS services or with the VPN service itself.
    Any advice and potential solutions would be greatly appreciated, as I have spent quite a bit of time trying to figure this one out by myself.
    Thanks in advance, and I hope to hear from folk soon.

    OK - here's how my router is configured:
    NAT (Type = Destination) Public IP address to VPN Server IP address (I had a problem when I didn't have the NAT Type set properly)
    I have a separate public IP address reserved for VPN traffic, but that's not necessary if you set up the order of the rules on your router properly. It's just easier to have a separate IP address.
    These are the ports I have open:
    UDP - 500
    UDP - 1701
    TCP - 1723
    TCP - 3283
    UDP - 3283
    UDP - 4500
    TCP - 5900
    TCP - 5988
    I have these ports open to accomodate remoting in via Apple Remote Desktop.
    However, since Mavericks, I can't use ARD anymore. But I can use Back to My Mac and Screen Sharing (go figure!) to get to my server and then from the server I can use ARD within the network.
    Don't know if that helps or not, but it works for me.

  • Usb will only work for powered devices

    I am having an issue to where my USB ports will only work for devices that have power supplied to them, ie an external hard drive that has a power adapter and not for devices that do not have power supplied to them.  I was seeing if anyone could help me resolve this issue?
    I have a Macbook Pro 15 inch Late 2011 model w/ the 2.2 Ghz i7 Processor.

    This is simply a case of the USB ports not being able to provide enough power. I do not know if there is a way to change this.
    This is highly unlikely, the USB specification (to which Apple adhere) requires a constant 1 amp at 5 volts, a peak of 2 amps for a brief period is available. All reputable manufacturers adhere to this spec, it is more likely a fault condition.
    To the OP, reset the Pram http://support.apple.com/kb/ht1379 
    and reset the SMC http://support.apple.com/kb/HT3964
    Reboot the machine and try again.
    If this brings no relief you should follow Oglethorpes advice and take it to Apple for repair.

  • Port forwarding stops working several hours after reset

    I have a WRT350N (fw v. 1.03.2).  It's connected to an Alcatel ADSL modem (PPPoE configuration).  I've configured port forwarding to allow HTTP and SSH into a linux box on my home network (static IP).  I am able to get to the linux box from outside for the first few hours after I set up the configuration, but a few hours later I am no longer able to get to it from outside - port forwarding stops working though the settings remain as I'd left them.  Over the course of various attempts I've had the external connections just die (404 errors, host not found, etc) and sometimes the connection went to the router - getting the WRT350N login prompt (remote management is turned on, but on port 8080, not 80, so this was unexpected).
    The only way I've found to resolve this is to reset to factory defaults and reconfigure.  Then it works again for a few hours and shortly is again not forwarding.  I've tried other ports (VNC, RDC, telnet, SMTP) and the forwarding stops working on all ports at the same time.  My home machines are able to get out to the internet with no problems.
    I thought the router had a hardware flaw so i replaced it with an identical model yesterday, and sure enough, today I'm again stuck without external access to my home website.
    Any thoughts or suggestions would be welcome.
    Thanks,
    Nick

    I was able to trace the problem to torrent downloads.  It seems the router wasn't handling all the concurrent connections when handling torrents.  I haven't had problems since i stopped downloading torrent files.  I did add a static port mapping and configured utorrent to run on a single port on a machine with a static address but haven't had cause to download any torrent files since then, so i don't know if that will fix the problem.
    That being said, i've had no issues since i stopped the torrents.

  • Cannot get port forwarding to work on EA6500

    Hi,
    I have an EA6500 to replace the old WRT54G. I have an Apach server on my PC. On the WRT54G, I could easily set port forward to the server, it was working fine. But on the EA6500, I simply couldn't get it to work any more. What am I missing?
    TIA

    Thanks for the reply.
    As it turned out for some "security" reasons, EA6500 port forwarding only allows access from outside of the network, but not from netwrok behind the router.  So annoying, however I found this work around

    look for poster sflick1's solution, it really works. 

  • Port Forwarding not working after 7.7.1 Firmware update

    I bought the new 6th generation Airport Extreme today, and after I set it up, everything worked great.  I have a VoIP phone that needs to have traffic on port 5060 forwarded to it, and that worked just fine as well. 
    However, I then updated to the 7.7.1 firmware, and the port forwarding stopped working.  I tried a hard reset of the Airport and re-entered all the settings, but it still didn't work.  I spent about 30 minutes on the phone with 2 Apple support people who tried hard, but couldn't help.  They also couldn't find a way to download the 7.7 firmware, so there was no way to downgrade.  They suggested I go back to the store and exchange it for another one, which I did, and now it all works again.
    Has anyone else had issues with port forwarding on 7.7.1?  I'm just wondering how I'll ever be able to update the firmware, since failure means having to get a new Airport.

    Huh,
    turns out the problem went away with another restart of the Mac Mini. I'm still uneasy about it though, as I do not understand how it went from working to not-working over night in the first place. But, at least for now, the problem seems gone.
    Thanks for commenting.

  • E2000 Port Forwarding Stops Working

    I am using port forwarding for running a webserver. All is working fine. After a random number of hours or days, the port forwarding stops working. I can get in and look at the settings and they are correct. I can then change something on the port forwarding screen and resave it and it starts working again.  Do I have a bad unit ?

    Webserver might not be set to static IP. Try setting the webserver to static IP first, then make sure that static IP is enabled in the Port Forwarding screen of the router's web-based setup page. Also, protocol should be set to BOTH (TCP-UDP). You can also try having less firewall/AV restrictions on the web server (or none at all) and set MTU to 1400.

  • Airport Express G getting Port Forwarding to work from Airport Extreme N

    I have an Airport Extreme N connected to a cable modem. I have an Airport Express G in another room, connected to a Local Ethernet Network. The AE G is setup as a WDS Remote to the AE N. Connectivity works and all is well.
    What doesn't work is when I try to forward ports from the AE N to a device/system connected (via ethernet) to the AE G. The kicker is the port forwards work from "inside" the network. Outside they don't. I have been able to forward ports to anything connected to the N directly or wirelessly.
    Any thoughts on what the proper configuration of the AE G or the AE N to get port forwarding to work from the AE N through to the clients of the AE G?
    I have DHCP, and the clients of the AE G are getting IP addresses and working as they should.

    I checked that. I can forward ports all day long to anything connected directly (or wirelessly) to the AE N. Anything connected to the AE G, ports won't forward. For some reason the AE G in bridge mode is not letting ports forward through.
    Thanks for responding, though.

  • RV215W router port forwarding not working

    RV215W router port forwarding not working.
    Port forwarding works for a short period of time, then stops working.  Reboot router, works again for short period of time, then stops again.
    I have updated firmware to latest.  I had seen other similar bugs posted for 220 and I think 180, not sure if this router has similar bugs and waiting for fix release to firmware.
    I had recently purchased two, one deployed, will hold off on other now because of issues, and may have to move to different unit if a resolution not found this week.

    It's not just single port forwarding that has bugs, the entire router has bugs and simply does not work as advertised. I have found the following bugs/aspects of this router that just does not work correctly: 1. If you have to open ports, and who doesn’t, this router will eventually stop accepting packets from WAN>LAN. You will still have Internet access but no open ports. A reboot will fix this problem. Oh, by the way, this router has no scheduled reboot option! <--That would be a workaround but a welcome one for this router. 2. Firewall Access rules do not work!! Yep, a Cisco router and basic functionality simply does not work. I called Cisco and even though the tech saw the router not working denied it was a bug! Said we have to do port mirroring, setup a workstation with WireShark and capture packets so we can debug the issues.  That would take several hours. I told him I would have appreciated if Cisco would have debugged the issues with their router BEFORE they shipped the units. Stay away from Cisco Small Business Routers. I wish I had. And if there are any Cisco die-hards out there willing to prove me wrong, just reply to this and please, prove me wrong that the RV series and specifically the RV215W is not JUNK.

  • Safari and firefox stop working after a few minutes of browsing, regardless of what site I'm on. I have to restart my computer to get internet access again but it only works for a few more minutes, then I have to restart again. Please help!

    Safari and firefox stop working after a few minutes of browsing, regardless of what site I'm on. I have to restart my computer to get internet access again but it only works for a few more minutes, then I have to restart again. I don't get a spinning ball, it just stops working at whatever page it's on. I can close the program just fine but when I re-open it, either safari or firefox, it freezes trying to load the hompage. This started a few days ago after trying to stream a movie on my computer. I'm on a Mac Air OS X Version 10.6.8 and have downloaded all updates. When I go into finder, it says I have over 80 gigs available. Is there some other memory cache that I need to check? Thanks so much for your help.

    It's not a router problem as I explained in my post. If it was a router problem then I wouldn't have the problem everywhere I go. It is an issue with the software.
    Then I guess the millions of people running 10.5.7 with no issues are just hallucinating that their machines are working fine?
    I'm not trying to belittle your issues; you're certainly having them and I know first hand how annoying an intermittent AirPort issue can be. (In fact, mine was due to an AirPort driver bug that no one else seemed to suffer from.)
    The single best diagnostic you could do is take your system running 10.5.7 to an Apple Store, and try using their in-store network.
    If your machine performs flawlessly, it may be a router issue.
    If your machine has connectivity issues there, it may be a hardware problem with your machine.
    There have been numerous people in multiple threads over the years who swore that an update was buggy because things used to work, but returned later to sheepishly admit that they took their machine in, a problem was found and fixed, and now their Mac works flawlessly with the newer software.
    But simply reinstalling 10.5.5 in no way means the explanation of how firmware bugs may be at play here is incorrect.
    In the context of that explanation, all you've done is possibly reinstall software that asks to add "2 + 3."

    Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

    This isn't an issue. Notice the screen prior to the one that shows usage has an iCloud section and a Manage Storage button. For this button to activate ios needs to download a few kb from icloud. Switching back to this screen forces ios to download those few kb.

    You need to give more info..
    Firstly only works for what.. networking.. backup.. wireless. You need more nouns.. more adjectives... describe what you want and what fails.. then we can figure out why.
    Most likely you have bridged it when it should be in router mode..
    Most likely you are using Lion or ML which has the airport utility bridge the TC by default.
    Change it to working as a router. That might help.
    If you press reset button it will default back to router btw.
    If you are on Lion.. use a real utility. http://support.apple.com/kb/DL1547
