Dhcp setting and port forward

I am using wrt54gx4. I have a IP camera connected to it. I can view the live images on the intranet and internet. Not too long ago my DSL company upgraded my DSL modem to a newer model. Then I can not connect to the internet by PPPoe. DHCP is fine. So the only connection type works is DHCP. But now I can not view the live images on the internet. I can only view the live images on intranet( I mean if I open web browser and type http:///192.168.xx.xxx:4545, 4545 is the port, I can view the live image), how can I solve this problem?

You probably have the notorious double nat issue. I'm sure your new modem is actually a gateway so you can either put it into bridge mode and do PPPoE from the wrt54gx4, or more simply, turn the wrt54gx4 into an access point/switch by using option #1 in this guide. 
After using option #1, you should open any necessary ports by accessing the gateway's GUI. 
I don't work for Cisco. I'm just here to help.

  • Very important information: No access, but Static IP set and port forwarded?

    Here is some important information I just learned, and I hope it will benefit the entire community.
    So, I have a WRT54G router, and I was trying to make a webserver. Everything should have been working fine, but I could not access it when I tried to use a proxy. (To eliminate local loopbacks.) I contacted a support rep at our favorite site, and after about 2 hours of going back and forth, they suggested I set my static IP address to something the DHCP range DID NOT cover. I did, and viola, it worked.
    I can't honestly say why it did, or why I had not known of that before hand.
    Point in case, try setting your Static IP address to one that is not included in the router's DHCP range.
    I hope this information will be posted everywhere.
    Enjoy!
    ~TGP1994

    In Linksys routers, the DHCP server expects to have full control over all LAN IP addresses within its range.  It does not expect you to assign one of its addresses (so this is likely the cause for your problem).   Normally, any fixed (static) LAN IP address must be outside the DHCP server range, and it cannot end in 0, 1, or 255.

  • I have the new Air Port Extreeme model A1521 and I need to set up port forwarding for HTTP. HTTP is not on the list in the set up. Does anyone know if any of those choices work for HTTP?

    I am on a Windows 7 Ultimate PC and right now there is no Airport utility for setting up the new Apple Extreme so you have to do it on your iPad or iPhone. Does anyone know how to set up port forwarding for HTTP to get to DVR security cameras? There is nothing in the list that indicates HTTP port forwarding.

    Thanks for your reply Tesserax as I did figure this out on my own. It took a bit because all of the options are not clear what they are for like the previous Airport Extreme and Apple does not support or guarantee that port forwarding will work for you application nor did any of the Apple support persons I spoke too have any knowledge for this feature. You also have to fill in the public if you are viewing through someone else's Wi-Fi or on your cell phone carrier network. This new Airport Extreme is a bit different since you cannot use the Airport utility on a PC like the older model and if anyone else is reading this they should be aware that if you do not have an Apple computer, iPhone or iPad and I'm not sure if some of the other network enabled devices like iPod Touch that you must use that can do it, there is no Airport utility for the PC and you would be wasting your money or have to take it back and get another brand wireless router to use if you do not own any of the above mentioned Apple products.

  • How do you set up Port Forwarding for ARD 2.2 in AEB N?

    Help,
    I'm a novice at Apple Remote Desktop (ARD) - not an IT guy, so it has to be pretty basic and detailed.
    How do you set up Port Forwarding for ARD 2.2 on the Apple Airport Extreme BS router, 802.11 N. I have one at each end of the internet connection. At one end I have an Airport Extreme N router with 2 macs and eventually 1 windows XP machine (if I can) that I would like to be able to connect to over the interenet (the clients) and at the other end, I have a Mac with ARD 2.2 installed also with an Airport Extreme N router. Note: Both routers use Static IP addresses and all computers use static IP's internally not through DHCP. What are the settings or directions to do this.
    I have read and printed out the directions for Configuration of ARD 3.0 that are posted many times in the ARD discusion group, but it uses a Linksys router ( http://www.starkpr.com/ard.htm posted by Dave Sawyer). The Mac router is different, particularly with the place to set a Private IP address. I'm not sure about alot of things, but especially about the Private IP address, what number do I set it to, the one that is in my Network connections list? It automatically changes to a different number in AE N setup for Port Forwarding (by one) as if it is not suppose to the same?????
    Are there any directions available that are as straight forward for the Airport Extreme N router, as the one's that are listed here for the Linksys Router's? ( http://www.starkpr.com/ard.htm )
    Any and All help will be greatly appreciated.
    P.S. I know I should have 3.0 but bought 2.2 just weeks before 3.0 came out and they would not give me an upgrade price, so I'm waiting for 4.0 to upgrade.
    Thanks,
    Jim

    Try the following for each AirPort Extreme ...
    AEBSn - Port Mapping Setup
    To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
    1. Reserve a DHCP-provided IP address for the host device.

  • How to set up port forwarding on extreme with NAS

    I've purchased a NAS (Synology DS211j with 2 caviar HD) over a month ago. Setting up the NAS for wireless connection locally was easy. I've been trying for 3 weeks on how to set-up port forwarding on my airport extreme base.

  • Set up Port Forwarding?

    Is it possible to set up port forwarding directly on an iMac?
    This is for video streaming from a house camera, over the net.
    I have a simple cable modem, and no router or gateway.
    I would rather avoid buying a router, or airport exteme, if I could.

    You can't avoid buying a router. Every home or business network should be behind a NAT router of some type.

  • Are "Back to my MAC" and "Port Forwarding" mutually exclusive?

    I have been using APExtreme and Port Forwarding successfully for several weeks now. The PF is to allow access to game players on a PC which acts as a server on the web. All Good.
    One more thing, I have a ISP provided wireless modem/router to talk to the cable and the world. It seems to work either bridged or un-bridged.
    I have disabled the wireless on the ISP's modem/router. (Actually the ISP's device doesn't hold a candle to the APE.)
    Still all good.
    So the firewall is on in the APExtreme and none on the modem router, and I have a port defined for my gamers to get access to my server in the APExtreme.
    I now want to implement Back to my MAC on my MBP and my other Apple devices. I believe these use iCloud for which I have an account and it seems to be working well with my iPhone.
    In Properties, when I select BtmM, iCloud says communications will be slow if I have port forwarding on. Also I will not be able to use the router function in my Modem/router.
    I'd really like to have the modem/router firewall up, and do the port forwarding there, but the BtmM will likely not get through.
    So what does anyone suggest?
    Can I use BtmM and port forwarding without too much degradation?
    Please advise.
    Thanks
    Barry

    To best answer your question on whether the two are "mutually exclusive," let take a look at how Back to My Mac (BTMM) basically works.
    BTMM - General Requirements
    OS X Leopard 10.7.3+
    Active iCloud account. Each Mac & the AirPort router, that will be relying on BTMM, needs to be configured with the same account.
    A publicly reachable IP address for your router.
    A router that supports either NAT-PMP or UPnP. For AirPorts, be sure it is running 7.6.1+ firmware.
    BTMM uses TCP port 5354 and UDP ports 4500 & 5353 for communications.
    BTMM - Basic Communication Flow
    For a computer connected to the Internet via a router, BTMM "asks" the router for its configuration information. For a router, like your AirPort, that uses NAT-PMP, BTMM will ask the router to assign arbitrary public ports. In turn, the router will provide these port assignments (& the router's Public IP address) back to BTMM.
    BTMM then sends this information to the iCloud account. In background iCloud updates a special set of DNS entries to be used by BTMM. These entries are then made available to all BTMM clients using your iCloud account. When a computer, with BTMM enabled, uses your iCloud credentials, it automatically retrieves a list of all other computers/routers that are registered with the same account. All these devices should then appear under the SHARED section of the Finder.
    When attempting to connect to a remote computer (or router), BTMM creates a secure connection to that remote device using the information from the iCloud account.
    Once the connection is established, the devices can then communicate with each other.
    So potentially, unless you are using Port Mapping for any of the ports BTMM uses, they should not conflict.

  • VNC without access to set up port forwarding

    I just bought the VNC Viewer app for my iPhone 4 and got it to work over 3G and wifi with my macbook pro connected to my home network. I know very little about networking but I knew enough to be able to set up port forwarding to my ip on my router at home. The problem is that I am a student in college right now, so my computer will be hooked up to the schools network when winter break is over. I have no access to set anything up on the network at school, so how will I get this to work? I made a host name at no-ip (does that allow me to connect to my computer even when my ip changes?), and I read something about being able to set up an ssh tunnel to make it work...maybe? I now have no idea what to do and the other forums I've read about this topic are using language that I am not familiar with. I need some network education! Again, the problem is setting up my MacBook Pro to allow a VNC connection on a network I have no control over. Thanks!

    My suggestion is using TeamViewer.com (they have both a Mac and an iPhone app) and it is free for personal use.
    Team viewer has the ability to work across routers and corporate firewalls.
    The problem with ssh is that it also needs port forwarding the same as VNC. You could have your Mac at college ssh to a Mac at home, setting up a reverse tunnel (ssh -R). You then VNC to the Mac at home, and instead of attaching to a VNC server at home, you connect to the ssh tunnel listening for connections. You would have to always have the tunnel established from your college Mac to a home Mac (or it could be a Linux box at home). And at home you would also need to port forward port 22 so your college Mac and ssh into your home Mac.
    It might be an interesting exercise, but I think you would be happier using TeamViewer.com

  • Xbox 360/one problem and port forwarding

    For a couple months now (since I got my AirPort Extreme) I have not been able to connect to a certain friend on xbox. I can connect to anybody else however. The only way we can (kind of) connect is if somebody else is host and we both connect to him.
    My NAT type is Moderate. When I try to test my connection on my xbox it says that I can connect but I am limited in matchmaking (this is joining games and using voice chat, which is the problem named above for my particular friend). The xbox shows the error and suggests that I enable UPnP or open the port 3074.
    The problem is that I have already have! I gave my xbox a static IP and forwarded the port 3074 to that IP.
    (I have also tried forwarding all the ports that xbox live uses to the xbox. These being:
    Port 88 (UDP)
    Port 3074 (UDP and TCP)
    Port 53 (UDP and TCP)
    Port 80 (TCP)
    as found on the xbox website...  https://support.xbox.com/en-US/xbox-360/networking/network-ports-used-xbox-live
    I made sure to put them in the right text boxes for UDP and TCP so that is not the problem either.)
    I know that the AirPort Extreme does not support UPnP but does have a similar thing called NAT Port Mapping Protocol which was already enabled. (I tried all possibilities of enabling/disabling NAT...Protocol and port forwarding/not port forwarding.)  ---  This is not the solution as I see it
    In short: My xbox tells me to open port 3074. I already have. It still tells me to open it and still won't work.
    I posted this on the apple discussion page (instead of the xbox discussion page) because I know that it's not an xbox problem. When I had my old linksys router it worked perfectly.

    I have this exact same question and problem.  I know this doesn't help, but would appreciate any updated information if you find an answer.  I'll keep working on this also and let you know if I find an anwer.

  • How do you set up port forwarding on an IPad 3 4g connection?

    Please let me know how to set up port forwarding on the iPad to point an outside port to one of the devices connected to my iPad hotspot. Thanks.

    I'm not sure if the 5.4.1 version that you have will do what you want. Did you mean to say that you had installed the 5.6.1 version?
    Sorry, I do not have a PC here handy to test, so you will need to wait for another PC user who can give you step by step instructions.

  • WRT54G Setting static ip and port forwarding for Xbox360

    1)This is my first post and I'm a little new at this. I have a WRT54G v5 router with the latest firmware update. I have the proper ports fowarded that I found on this site. I basically want full priority to my xbox360 because I have been having some lag issues and dropping out of rooms, especially when someone is on the computer. I set a static ip on the xbox, I just picked 192.168.1.36 (Is that an ok #?).
    2)I have everything hardwired so I disabled 'wireless access web" under administration and I also disabled "wireless network mode" under the "Wireless" section. Is this correct or ok?? I don't want my neighbors or anything wireless accessing my router, will that do the trick?
    3)I'm looking at the first page you see at the linksys config page (under setup) and I see a section that says
    Static DNS 1:xxx.xxx.xxx.xxx
    Static DNS 2:xxx.xxx.xxx.xxx
    Static DNS 3:xxx.xxx.xxx.xxx
    My question is do I need to put the static ip that I assigned to my xbox in one of these static DNS entry spots??
    4)Under: Applications & Gaming>QoS I set Ethernet port 4 (the one my xbox is on) to high priority. Is that all I need to do to get priority to the xbox over the computer? Or do I need to enter something under "Device Priority" such as device name, mac address, etc.? And do I need to enter something under "Application priority" such as: Application Name, Optimize Gaming Applications, Priority, and Speciific port #, etc.??
    5) Should I disable UPnP?
    It's kind of a lot of questions but I really want to understand this fully, any help is greatly appreciated.Thanks alot!

  • Help setting up port forwarding for Ekiga

    Hi
    I am trying to set up Ekiga on my Arch X86_64 box but I can't get port forwarding to work on the Thomson TG585v7 wireless router, which I am sharing with a neighbor.  I have tried some how-to's I found via Google and set up Application/Game Sharing for the ports Ekiga uses.  I also set up static IP connection as it seems to be needed by the router for port forwarding to work but Ekiga still reports that it cannot set up my network connection and asks me to set up port forwading manually, which I have already done.
    I would very much appreciate any help to get Ekiga going for me.

  • Tarantella and Port Forwarding

    Hi,
    I just installed a Tarantella SGD EE 4.0 Server which will be
    established in a firewalled and nat environment.
    As the ports 80,443,3144 and 5307 are already captured in this
    environment there will be port forwarding as follows:
    30080 -> 80
    30443 -> 443
    33144 -> 3144
    35307 -> 5307
    When I now try to reach the Server with a browser and
    http://firewall:30080 I'll see the 'normal' screen "Welcome to Your
    Secure Global Desktop Web Server".
    Trying to login fails with no significant reason in /opt/tarntella/var/log/.
    Next what I did was to scan the machine with nmap, this is the result:
    tarantella:~ # nmap localhost

    Where do I have to check what went wrong?
    Thanks,

    I don't think this is a Mavericks issue. Read the instructions that came with your camera. Is the camera running correctly? Is port forwarding in your router set up correctly? Does your ISP allow incomming connections to port 80? What ip address are you using from the outside world, you can't use your LAN ip address? The security/camera system must be running some type of web server to allow access. Is this running correctly? Does the camera software work with Mavericks or is it designed for older OSX versions?

  • Trouble with bridge mode and port forwarding

    I have a Westell Model 6100F DSL modem in bridge mode into my network and I'm having trouble forwarding ports. Is there any general guidance available to do this. I have set many of my friends networks up to allow port forwarding but all have been on other service providers, mainly cable. (my experience) My network is the only one I have had trouble with.
    Basically, my question is, while in bridge mode, does the modem forward all incoming traffic to my NAT router or do I need to apply special port forwarding settings in the modem to allow this?
    If bridge mode is the reason I cannot forward the ports, can someone explain how to set the WEstell 6100F back to factory defaults so I can start over. 
    Any other suggestions?
    Thanks in advance.
    Paul

    If bridge mode is set up correctly, your router should be holding the Public IP address (basically not something that is a 192.168 address) as shown at http://www.whatismyip.com/ and compared against what IP your router has.
    If your router has the public IP, all problems lie with either your router or your PC's firewall and configuration. I'd check out portforward.com for some guides on forwarding ports for your router or poarticular application if you need some additional help.
