NAT Loopback: Low broadband bandwidth


I have a first generation WNDR4500 as my lan, behind the internet gateway router.

There is a server on the LAN and some customers (smartphones, computers) access from the LAN and WAN by using the internet domain name.

I recently discovered that the bandwidth is very low, while the client devices are on the local network. When I change the server details on devices with a LAN IP address, the network speed is available. Therefore, I think that the loopack on the WNDR4500 NAT function does not work correctly and that it reduced the available less than 1 Mbps bandwidth. The internet connection is down: 40mbits / Up: 8 Mbit.

I checked the QOS settings and everything seems fine, for example no. changes when inputing a lot on internet bandwidth.

Has anyone experienced this problem?

Thanking you in anticipation.


The basis of engineering, the only way to get this to work is to use the IP address.

There will be no update firmware to correct this, since the unit already is EOL.

I apologize for any inconvenience that this may cause you.

  • NAT loopback

    Hello everyone!

    I have a problem with product [email protected] CheckPoint and CheckPoint told me I can perform NAT on my PIX loopback to solve the problem. Can someone tell me how to configure the PIX of NAT Loopback?

    Thanks in advance, broadband



    Interfaces loopback is available in IOS. The only exception-NAT, you can do it in the PIX is "nat 0" refers to an access list.

  • Need a home WiFi router, which takes in charge the NAT Loopback


    I need to buy a new router that supports NAT loopback so I can access internal LAN servers of other customers of LAN by using the public URL address (external).

    Ideally, I would like to talk to services to customer or technical, but support at an alarming rate, Netgear make that available. It makes me seriously concerned by the lack of technical support and maybe I wouldn't even go with Netgear in these first impressions. In any case, let's see how this investigation goes first.

    So I need a cheap home router, which offers a good reliable fast WiFi connection like wired connection, IP and of course NAT loopback address reservation. Oh, and it should be on sale in the United Kingdom.

    Thank you for your thoughts people!

    @Frankie3142 Our routers Nighthawk support NAT Loopback.

  • How to quickly get 100 + photos from iPhone in pictures on iMac with the download speed very low broadband?

    Hi all

    I have an iPhone 6 Plus running iOS 9.3.1 and a retina iMac running OSX El Capitan 10.1.4.  I use iCloud photo library and I like the idea of having all the pictures synced across all devices.  This works well for one or two odd photos I take here and there.

    I have just been on vacation and taken 100 + photos with my iPhone and want to create an album of photo printed on my iMac, but the problem I am facing is that it takes so long to get the pictures on pictures on my iMac.

    My download speed high speed is very low - on 0.3Mbit / s, so the photos are always download to iCloud from my iPhone now, and I guess it will be another day or two to complete.

    Is it possible to get the photos from my iPhone to the iMac more quickly without creating duplicates or spoil my library?

    It's so frustrating to have to wait 5 days after her return from vacation before you can start making a photo album.

    Thanks for any help,

    Kind regards


    You can connect the phone with USB and import or use iTunes sync or Capture of Image - this can cause a problem with duplicates

    And of course, you can stop by a store StarBucks, Apple (or other WiFi hotspot with good service) and complete quickly


  • SMU FlexRIO DMA FIFO host read the FIFO overflows broadband bandwidth/DMA issues

    I'm working on an application that uses 2 modules FlexRIO, and 2 LVDS digital I/O adapters.  I'm driving each of the SDC A/SDC B ports on LVDS 16-bit data at 50 MHz adapters.  The FlexRIOs are expected to receive the data and write down them on four targets-to-host DMA FIFO (one per connector SDC), or two by FlexRIO.  The host reads the FIFO and brings together a series of tables each FIFO output 2D.  Ultimately, the individual tables (we're each a quarter of single image) will be assembled in simple images, but I haven't gotten that far yet.

    The duty cycle for the data is about 80% (in other words, I'm only transmit data to the FlexRIOs 80% of the time, the rest of the time the transmitters are disabled), so the flow is about 80 Mbytes/sec/port total invasion, or 320 MB/s on the four FIFOs DMA.  I find that the acquired data gaps sometimes inside that line up along the length of the material part of the DMA FIFO in FlexRIO modules.  In other words, if my memory FIFO DMA are set to 65535 length, I'll see a break in the data acquired at the word of data 65536th.  Data is a waveform of sight, which is essentially just a counter, so it's easy to see the break in the model.  For the words of first 65535, adjoins the data, then from Word 65536 model is discontinuous and starts counting again from there, contiguously.  At the beginning of the acquisition, the FIFO is erased: the beginning data read from the FIFO is always aligned correctly, so I know that the process starts at a good point.

    The error is not always the case: sometimes I get continuous data through the point 65536.  In addition, the error occurs independently between the four FIFO: on a particular race, a FIFO could have data of interest and some bad.  Rarely, all four FIFOs have good data.

    The fact that the gap of the configuration is to the point even the depth of the FIFO DMA tells me that fills the FlexRIO FIFO, the FPGA hardware without the system managing to move to read, which means that the data gets dropped during the period that the FIFO is full.  Then transfer to the host comes into action, there again is the space in the FIFO, and the data is once more contiguous in FIFO memory for a large amount of data (I have not yet tried to locate a second gap in the data of a single acquisition).  It seems therefore that the host doesn't have enough bandwidth between the FlexRIOs and the host of RAM to prevent the filling FIFO, or comes along some software process on the host that is temporarily stop the ability to instantly transfer.

    Are at - it a specification for the SMU flow system that would indicate that we are trying to use too much bandwidth?  Or are there priority controls on DMA FIFO that would allow us to raise the priority of the FIFO transfers as they are guaranteed to go in preference to other system tasks?

    System Specs:

    SMU-1075 chassis

    SMU-8135 CPU

    2 SMU-7962R FlexRIO modules

    2 digital i/o modules of NOR-6585

    LabView 2012 32-bit SP1 version 12.0.1

    A suggestion of an applications engineer of NOR and some experimentation has solved the problem. It turns out that I was calling the method FIFO of DMA stop just before the outbreak of the transmission of the data via a control for the FPGA FPGA VI. I did this in order to clear the FIFO before you begin data acquisition, but I didn't know that this method disables also transfer data between the memory FlexRIO and host. Following this call, I trigger the FPGA code to start filling its FIFO and then begin reading. Calling the Read of FIFO of DMA apparently light up the transfer back, but it seems that the host VI has been randomly slow down enough to move to the bed such as filling the side FlexRIO FIFO and dat would be lost. I changed the host VI to insert a FIFO method call start before the trigger for the FPGA signal, and the problem is now gone.

  • MPLS TE tunnel broadband bandwidth and ip rsvp bandwidth

    I have a few questions about how to reserve bandwidth in MPLS TE environment.

    1. we need IP RSVP bandwidth in any concern in MPLS TE environment interface, right?

    2. What is the purpose of ip rsvp bandwidth?

    3 tunnel MPLS traffic engineering connection XXX, the define command band bandwidth flow initiated by head, if sending more than XXX flow, how it works? Drop excessive packet in the stream?

    Any point is welcome! Thank you!


    (A1) to the right.

    A2) with the "ip rsvp bandwidth" it indicates how much bandwidth on an interface can be booked by MPLS TE tunnels.

    A3) characteristic misuderstood most probably is MPLS TE. It is a pure function of the control plan. So, there's comparison of reserved bandwidth compared to actual bandwidth used or nocheck.

    You can configure an MPLS TE tunnel with 1 Kbps ("mpls traffic engineering tunnel 1") and send 10 Gbps on the way and NONE will be given.

    Where there is an interface in the path, that is supported, then packets will be handled independently having a tag to tunnel or not.

    You might ask: what the point of MPLS TE, then if I have can´t give guarantees of bandwidth with it? Answer: MPLS allows YOU a selection more complex and controllable path in MPLS environment. In addition features such as Fast ReRoute (FRR) are interesting.

    I hope this helps! Please note all messages.

  • MCU4500 series and Polycom HDX broadband bandwidth interop


    A customer brought it to my attention and I was not able to determine a good reason for it yet.  First of all, here are the settings;

    -MCU4515 4.4 (3.49) running

    -Polycom HDX (a 7000 and a 8000) running 3.03

    -MCU and endpoints registered to a Porter, no bandwidth restrictions (they say)

    -calls to 1.2 M

    -MCU call termination points, H323

    When connecting endpoints HDX, the incoming bandwidth for the MCU is half of the outgoing bandwidth to the HDX.  I can't find any setting in the MCU which has an effect any on this.  By default the settings of bandwidth on the MCU (inbound and outbound) are set more than the real call rate.

    I tried to test with a 4.4 (3.49) running of the MCU4510 and two Cisco endpoints (EX90 C90), endpoint and saved for a VCS and the MCU points not saved.  The incoming and outgoing call, rate stays.

    Y at - it no unpublished data of interop MCU which has a reference to this issue?  The customer said that wasn't a problem when the MCU was at 4.2 (1.50).

    Thank you!

    Thanks Bob.  The reason why this is happening now is that MCU had some previous issues by honoring the bitrates etc..  This problem has been fixed in MCU 4.4 under CSCuh81255.

    When HDX calls, it always opens LC for ExtendedVideoCapability at the beginning of every call.  This leaves MCU to split the BW cut in two for hand and when the system wants to send the contents of the content.  Given that the already contained open HDX channel to MCU, MCU must reserve the quantity of bioweapons for content when the HDX decides to send and do not exceed 1.25 meg in your case.

    I hope that makes sense to you...

    Let me know if it doesn't.

  • Deterimining broadband bandwidth/competitor users / connect from newspapers

    Hi guys,.

    Looking at the price survey, do not know where our app to, but something on the order of what I have listed below.  Somehow, I think that we are in a minimum use case:

    (1) 2 hours per day, less than 10 chat users simultaneous,

    (2) each session of cat less than 100 messages, 10 lines per message, per session?

    What that would mean in terms of use of resources?

    We have just run an internal alpha.  How to watch the use of resources?  Is there a way for me to see how much bandwidth / max users / concurrent connections have been used for a given account/room?

    I hope there is a quick and easy response.

    Quick and easy answers are my specialty =)

    See the graphs here. And we would be really interested to talk to you about your use case and use - we are committed to ensure that it is affordable as well. We think that we get to the numbers / a model that will make sense for all, but more data is always appreciated.

  • Bandwidth fine tuning


    Nice day.

    Thank you everyone for the wonderful support... we're trying to refine the configuration of bandwidth on our tours and need your help

    We have active .policing for Netbios trafficon our metro LAN circuit and 30% of the bandwidth is allocated (with bandwidth control), rest all that traffic has 70% of bandwidth. It's initially slow when the data is copied by several users.  We never see that circuit is used at 100%.

    Could you be it someone please let me know if we can capture the QoS configuration as far as Netbios can deal with the surplus of available bandwidth and should not cause any famine bandwidth for rest any cause of traffic which is critical.

    If there is congestion, no netbios traffic shouldn't be deleted.

    I think that the priority queues can be active but not an expert on Queuing technology :-(needs your help

    The problem with 6500 LAN QoS, it can prioritize different traffic, but priority is when there is congestion, which happens when the port is congested.  When you have low-speed bandwidth, you'll have a problems of congestion downstream, but your switch will not deal with it.

    Law enforcement doesn't create congestion.  You can ensure a portion of the traffic is unusable on its allocated bandwidth, but prevents them from using the available bandwidth, and it's not the same.

    Basically, the 6500, with LAN cards, does not lend itself to a low speed hand-off bandwidth.  If you want to effectively manage your problem, you need something "better."

    It is not a way to limit the bandwidth of the network through the windows. This can be done only between your router and you could contact the router manufacturer for help.

    In Windows 7, there is no network integrated monitoring tools. However, you can download and install the link below, below, network monitoring tool that takes care of your bandwidth monitoring network.

  • Conference TMS uses the wrong bandwidth with BBFRR

    Hi all

    I m currently faced with the following question:

    When booking a conference through TMS directly or through Outlook (with TMSXE) the bandwidth Conference when using BBFRR will be set to 1152 kbps regardless of the configured default 4096 Kbps or immersive IP broadband bandwidth in the World Conference of TMS. During a call directly to the conference expected the default bandwidth configured on the endpoint will be used. This brings me to the presumption that it has something to do with the maximum setting of IP bandwidth on each endpoint in TMS (see screenshot). You cannot change this setting because endpoint is saved to CUCM.

    TMS conference settings:

    Endpoint settings:

    I have no idea where this parameter, and I hope that someone here in the field can help me fixing this problem.

    -TMS 14.6

    -TMSXE 4.1
