Airport Extreme connected to TIVO: why I can not change Type firewall for IPv4.  Field displays IPv6 and is grayed out so I can't change.

TIVO requires certain ports to be unblocked.  So I try to add the ports requiring TIVO.  But when you try to add the default Type of firewall IPv6 Port Mapping ports and I can't change the value of the IPv4 Port Mapping because the input field is grayed out and no is not accessible.  With Port IPv6 mapping I enter values in all areas except for the IPv6 address because I do not know what value to enter.  I think the button 'save' ' is not available to hit because the IPv6 address field is empty or not valid.  Note: my router Mode is ' Off (Bridge Mode).  Same questions if my router DHCP Mode.

I changed my router Mode DHCP and NAT, then on the Type of firewall on the default page add ports, IPv4 Port Mapping and I could add ports but with this setting, I couldn't connect to internet in my Airport Extreme: my status remains orange light flashing.

I use Comcast and my Airport Extreme is connected to my Comcast router using ethernet.

I use my Airport Extreme as a router (wired and WIRELESS) and as a backup device.

My TIVO is connected to my Airport Extreme using ethernet.

How can I add the Ports requiring TIVO.

Golden in the networking rule. ....... Never try to configure port mapping when you have two devices on the same network the two acting as a router.

Unfortunately, this is exactly what you're trying to do.

You have three options:

(1) run the Comcast router "as what" and configure the port on the device of Comcast mapping... .the airPort Extreme must be configured in Bridge Mode when you do this.

(2) lance to the AirPort Extreme router Mode of DHCP and NAT and configure the ports on the airport map... the peripheral Comcast must be configured to operate as a simple modem in Bridge Mode when you do this. 


(3) lance to the AirPort Extreme router Mode of DHCP and NAT and configure the ports on the airport map... swap Comcast modem/router you have now for a simple modem (it will have only a single Ethernet port).

In other words, either the Comcast is defined as the router and AirPort Extreme is in Bridge Mode... or... the AiPort Extreme is configured as a router and Comcast must be configured in Bridge Mode.

If you choose Option 1, then we can not help you on a matter of Comcast router. In bridged Mode, the AirPort Extreme requires no configuration.

If you choose Option 2 or Option 3, then we the following port values that the Tivo device needs:

Public or UDP ports

Public TCP

UDP private

Private TCP

In addition, you need to find the MAC address for the TIVO.  It is a long code that looks something like this, for example:

A1: B2: C3: D4: E5: F6

A link to the Tivo instructions for port mapping would also be very useful.  I have done this with a TIVO in the past, but is for some years.

If all goes well, an expert of TIVO will post to lend a hand.

    ---------------------

    Although I think that the question is really the Airport Extreme also updates Windows 7 WiFi.
    Check with the system manufacturer and the real device manufacturer updates the driver.

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers under Windows 7 (updated drivers manually using the methods
    below is preferred so that the latest drivers from the manufacturer of system and device manufacturers are
    found)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    Download - SAVE - go where you put it - right click – RUN AS ADMIN.

    You can download several at once however restart after the installation of each of them.

    After watching the system manufacturer, you can check the manufacturer of the device an even newer version.
    (Those become your fonts of rescue system manufacturer).

    Repeat for network (NIC) card and is a good time to get the other updated drivers as windows

  • Why Muse does not change the names of certain images or property when exporting to HTML format?

    Why Muse does not change the names of certain images or property when exporting to HTML format? and how can I keep the integrity of the name that the image/file has been saved as?

    General Muse renames a file imported image if the image is modified to achieve the design or the exit, or if the name change was necessary due to a name conflict (two different images which had the same file name when importing).

    The design-time features that will modify an image include cropping, rotation, rounded corners and effects (drop shadow, bevel or glow). It is also true that, in rare cases, Muse will merge an image with other content to optimize page download performance. An example of this would be to place a background image on a block of text that contains the text using system fonts. In this case, rather than a single image for text output and a separate image for the background, Muse will combine the two into a single image.

    If an image is placed or imported by Muse and not tampered with, the image is crossed without modification (including the file name) at export/publish (with him except that Muse will always rename if two different images with the same name).

  • Can the Airport Extreme connect wireless to my wifi network?

    Hi all

    I have an Airport Extreme, which I use only for his Time Machine feature.  Best I can tell the only way he can connect to my wireless network is extending.  Is this correct?

    If I use it to extend my wireless network was is the negative impact (if any)?

    Thanks in advance.

    You can extend wireless or even join wireless to less the router that you connect to another router from Apple.

    If this is the case then it can work well if it is in the range... otherwise, you must plug the AE into the router principal by ethernet and put in place as a separate network wireless access point.

    Extend wireless is bad if you are linked to the main router wireless... which will cause huge slow down even if you are in a situation of apple router all.

  • The airPort Extreme has green light, but nothing can connect to it.

    My 5th generation AirPort Extreme suddenly stopped allowing all devices connect via WiFi or Ethernet. I can't see it in the AirPort Utility, I can not access it via the browser, and I've rebooted several times without success. I'm afraid, it may have just died, but I'll try to revive because while I can buy a new one, I hate the look of the new units. Any suggestions?

    Try powering down of the entire network... all devices... in any order you want

    Wait a minute

    Start the modem and let it run a few minutes

    Start the AirPort Extreme and run a full minute

    Keep a minute out one at a time until the entire network is back of boot devices

  • Airport extreme connectivity problems

    I got in and out of trouble with my Airport Extreme, which is less than two years. I started to lose the connection to the internet for 4 months now. Now, I get different errors that my extreme is overheating and another mistake he lost the DNS information for my Cox internet service. I'm running 7.7.3 and of course impossible to change the firmware. The only way I can solve the problem when it comes to the top is to do a reset on the extreme and wifi Setup. Is there anything else I can do to fix this?

    Cox has implemented IPv6 services in its system, which has been designed to be compatible with existing equipment. Unfortunately, Cox has now established that airport routers are not compatible with the changes they put in place.

    If you want to be able to use the new IPv6 service that Cox has put in place, you need to replace the routers of the airport with another brand that Cox recommends.

    If you want disable iPv6 Cox service, then this can be done on the router from Apple... and can help with your problems of connection. After the back if you want to try this.

  • Loading slow web page and with Airport Extreme connection speeds

    About 5 days ago, I noticed a significant slow down the loading of web pages. In some cases, I see a blank white screen for up to a minute before the page is loaded. In others, the page never loads at all. And sometimes they load very quickly as expected. This happens with my iMac that is connected to a router via ethernet, as well as my Macbook Air connected via Wifi to Airport Extreme.

    I have a high-speed internet connection by cable Comcast/Xfinity: Blast 250Mbps.

    I tried to connect my iMac directly on the model of cable (Arris Surfboard SB6183), and there is no problem. Download speed was 30Mbps 300Mbps and upload.

    Then, I plugged my Airport Extreme router again and connected the iMac to the router via Ethernet. Download speed dropped to 100 Mbps!

    This suggests that the problem may be with the Airport Express. It is not a wireless problem, because as you can see the download speed went from 300Mbp/s connected directly to the model 100 Mbps when connected to the Airport Extreme.

    How do I troubleshoot/fix this?

    One last thing: I did a speed test with my Macbook Air that is connected via Wifi and the Airport Extreme router. Download speed dropped to 35 MB/s.

    Direct connection to the modem is so very fast, suggesting the internet connection Comcast isn't the issue. Speed falls even with ethernet to the Airport Extreme router connection, then decreases even more with the Wifi connection.

  • Second Airport Extreme in Bridge mode, ethernet ports does not

    I have two routers, I want to use. The first is a time Capsule (old model 2 TB) connected to a single cable modem. The second is an Airport Extreme (also a little older, the 'flat' last body model until they began to sell towers). Both have the 7.6.4 firmware.

    The problem is that I want to use the second to extend my network, but I don't want to use wifi. I have the second of the WAN port connected via an Ethernet cable to the network served by the time Capsule, but when I launch the extreme in Bridge mode with a Mac Pro plugged into one of the ports ethernet to the extreme, it says it is not connected to the net.

    Y at - there a trick to getting the second router work ports ethernet when used in this way?

    Thanks in advance!

  • Why Canon does not have old adapters for my SLR camera lenses? I can get them with Sony, but not for Canon

    I have an old Canon Ftb with a goal of 1.4 fd. I'm getting into digital cameras now (just to have a 12 G for now, mainly used for underwater photography). I would like to stay with Canon, but I'm very annoyed that Canon doesn't have a way to continue to use their old lenses. Nikon, for all their flaws are much better at you can continue to use your old stuff.

    Then I find that if I'm going to Sony (Yes, really, Sony) can I use my lenses from Canon ol via an adapter. This my Canon, tell me it ain't so. You must have a way, I just have not yet discovered.

    There are many challenges with this and the "adapters" are to be considered with a certain scepticism.

    The FD lenses are mechanical - no electronics.  The case of the unit, on the other hand, has an electronic interface for the lens - nothing of mechanics.   This means that if you set the goal, you would have to manually set the aperture but also of manual focus of the lens.

    Your Canon DSLR had a split Prism focusing in the viewfinder to help.  A new camera does not work.  The reason why there is no help from the development is because most of the lenses are autofocus so it is simply not necessary.  This makes it particularly difficult to tell when you've worn exactly the goal.  Making it even more difficult is that any device with a sensor size of APS - C (most of them) have a small viewfinder that you had on your Canon SLR photography.

    In addition, the lenses are optimized for a specific back focus distance.  Canon's EOS cameras have a depth of 44 m from the mounting flange of lens at the front of the body at the level of development within the body.  When you use an adapter, it modifies that distance.  If you change too much, the lens behaves as if it is mounted with extension tubes, the entire range of focus is moved closer to the camera, and it can be is no longer able to focus to infinity.

    There are 3 parties that make these lenses... conversion kits but they do them for a few drinks (not all) and that they require a bit of surgery on the goal (e.g. this level which protrudes beyond the rear of the lens used to set the aperture value should go).

    But... the modern lenses are just so much better than the old FD lenses.   Requires really quite the dozen FD lens to make it interesting this fuss.  Also, I own a Canon SLR (AE-1) and a few glasses of FD... but have no interest in trying to use one of these lenses on my EOS DSLR cameras.

    I think that this question almost as Ford asking why they do not wheel adapters let wheels it T model mount on a Mustang of 2015.  The new wheels are so much better than the old wheels, you want to continue to use the old wheels.

    Leave your old lenses in the past.  Mine are on the shelf alongside my AE-1... body as a conversation piece.  I don't actually use them.
