Help with Time Capsule Double NAT error.

I've been reading different threads on this problem but have been unable to find a solution.
I recently replaced a dead SpeedStream modem with a Motorola 3360, per AT&T's (my ISP) recommendation. Since swapping the modem I've had a "Double NAT" error on my Time Capsule. The new modem is the only change. We connect every device: 1 G5 tower, 1 iMac, 1 iPad, 1 MacBook Pro via our wireless network. The Time Capsule is stand-alone, e.g., not connected to anything but the modem via the either-net cable provided.
Running 10.7.4, the Airport Utility is 6.0, the TC firmware is up to date as well 7.6.1
We've never had great speed but now it's slower than usual, I'm assuming because of the Double NAT error (two firewalls).
I've followed the AT&T website instructions, to the letter, for switching the 3360 to "bridge mode," letting the TC handle the IP address (correct?) = no internet.
I've also followed the support communities directions for switching the Time Capsule to bridge mode as well, letting the modem handle the IP address, the Double NAT error goes away but = no internet. In this mode I can't join my own network and I get a "your computer is using an IP address that's already in use" error, though everything but my laptop is off.
What I'm willing to try anything but I need very specific, step-by-step (noob) instructions. Many thanks.

I have to admit when I see Motorola modem I automatically think cable modem.. but yours is adsl.. so when you bridge the modem you have to use pppoe client in the TC.. not dhcp as you would with cable. Is that how you are trying it.
I looked it up and there is a thread almost identical. https://discussions.apple.com/thread/3808550?start=0&tstart=0
Bob.. gives instructions with pic in the thread on how to setup pppoe in the TC. This should work, although we have noticed some issues of late with the client not always handling IP correctly.
I am not sure why it fails when you bridge the TC.. that IMO should work without too much hassle.
I would download 5.6 utility
http://support.apple.com/kb/DL1482
It just does a lot more things than v6 in Lion.
Go to manual setup in 5.6 utility.
Go to internet tab
Go to connection sharing.
Set to Off bridge mode.
Update the TC.
Then reboot everything..
start in sequence.
1. Modem.. wait a couple of min.
2. TC .. wait again..
3. Clients.
What you have previously done may well be correct but not renewing IP addresses properly has messed up the connection to the modem.

Time Capsule Double NAT error

Hello,
I would really like some advice on double NAT and bridge mode before I respond to an error message on my mothers macbook/ TC settings. She recently had some extremely high uploads (approx 10GB that ate up all of her allowance) at times when she was not at her computer and so I reset her TC and changed the WEP password to something really obscure to try and prevent anyone from hacking in to her wifi network.
She has a basic set up: Cable modem connected directly to the Time capsule with no other airports connected to the network. She uses a standard 2010 13"Macbook to access the internet over wifi.
Twice in the last week (once before she noticed the massive uploads and today at about the same time as her internet service says she had a 150MB download that she did not have) she has received an error that says:
"Double NAT
This Airport wireless device has a private IP address on its Ethernet WAN port. It is connected to a device or network that is using Network Address Translation (NAT) to provide private IP addresses. You should change your Airport wireless device from using DCHP and NAT to bridge mode"
My question is - will following these instructions fix her download problems or make it worse?
Also, is there any other way I can prevent someone from hacking into her network.
All advice welcome
Thanks
Emma

Having a double NAT, indicates that TWO devices on your network are performing Network Address Translation, I am not a complete expert on this or anything but it's not that big an issue, you probably just need to turn off NAT on your Mom's modem.
But this definitely IS NOT causing her issue of using up all her Data allowance with her ISP. Having a double NAT just complicates the network and can cause problems with certain apps. But It will NOT increase data use.
You should use WPA2 as the type of network encryption.
You can use Mac Address Filtering as some kind of added protection.
You could have a Non Broadcast SSID but this again is really only trivial protection, WPA2 with a STRONG password is your best bet.
Hope this helps,
Anything else I can do just let me know,
PS you should check the DHCP client list or attached client list in Airport settings to see if someone else is using your Mom's bandwidth.
Regards,
John

Help with Time Capsule

I set up my new mac mini and hooked up it all up with my old router and all was fine. Solid internet connection. When I switched out router with Time Capsule, I cannot get an internet connection even thought it shows the wi-fi and ethernet is active.
I went in shopping today for a stronger router (better range and speed) and the sales man suggested the Time Capusle because it was a router with a built in hard drive for back-up.
Finally - i do have a broadband phone - so I have that thrown in the mix, but it worked fine with my old netgear router and the new mac mini.
I figured it would be a plug and play change. What am i missing?

You have done no setup.. what is your broadband type.. adsl or cable or other??
In any case how are you plugging the TC into whatever provides you internet.. if it is a modem it should be bridged.. and in the case of cable .. shut down and rebooted to allow it to connect. In the case of adsl, you should set the TC to pppoe connection.

Needing some help with Time Capsule Error. New to Apple Support and not super tech smart.

Can not get the MacBook Pro to back up to Time Capsule. Can any one help me with the following Error Please?
The backup disk image “/Volumes/Data/XXXXXXXXXX MacBook Pro.sparsebundle” is already in use.

We don't see that error much but it is about the easiest to fix.
Pull the power on the TC.. count to 10. Plug the power back into the TC.
Viola.. working TC again.

NEED HELP WITH TIME CAPSULE!

Hello, I am new to this forum and this is my first post. Currently I have a Macbook pro and it is really the only computer in my house I use. My Mom has a Macbook, My dad has a Apple Desktop and my brother a toshiba laptop.
I am running OS X 10.5.8 on my macbook pro, Snow Leopard on the other.
Tonight I got the time capsule, and I am really excited to get this working. To give a little background, I have FiOS and our modem is in the basement which runs directly to a verizon wireless router, MI424WR to be exact. I have a few questions about how to set it up because I tried to set it up like they said but when I plugged the Time Capsule into the Fios router and turned it on all I got on the Capsule was the blinking amber light. I ran an ethernet cord from one of the opened LAN ports on the router to the WAN port on the Capsule. I installed the Airport utility on my macbook and my dads desktop but still do not get any type of connection to the capsule. I am reading about bridging so I tried to do the manual set up in the Airport utility it just scanned and got nothing and I cannot even hit manual setup. My questions are..
How exactly do I set up the Time Capsule, as I described it does it sound like I have everything plugged in correctly?
Is it possible to completely get rid of the verizon router?
How do I get any of my computers to pick up the time capsule?
If you have any questions as to how I explained please just ask. I am really trying to get this set up because I do not want my dad to think he wasted 350 dollars on something that is completely useless for our home setup. Any help would be greatly appreciated. THANK YOU, Zach.

No matter what, even when the TC is plugged into my MBP with an ethernet cable it does not read it.
Disconnect any ethernet cables that you connected to the Time Capsule at the moment
Hold in the reset button on the back until the amber light begins to blink more quickly and continue holding the button another 4-5 seconds when this occurs. Then release the reset button.
Connect an ethernet cable from one of the available LAN <-> ports on the Verizon router to the WAN (circle of dots icon) port on the Time Capsule.
You have two ways to configure the Time Capsule using either wireless or ethernet.
To use wireless, click on the fan shaped Airport icon at the top of the computer screen and look for a wireless network with a name like Apple Network xxxxxx. Log on to that network first, then open AirPort Utility.
To use ethernet, temporarily connect an ethernet cable from your Mac to one of the LAN <-> ports on the Time Capsule. Open AirPort Utility.
When you open AirPort Utility, click Continue to follow the guided setup. You did not indicate whether you want to Time Capsule to provide a wireless network, but most users want that option. So, you when asked how you want to configure the Time Capsule, you would choose the "Create a new wireless network" option.
As the Jolly Giant says, you will need to choose Bridge Mode when you see a choice of how to connect in the setup process. If you are an experienced computer user, you may want to configure the Time Capsule manually, but I would not recommend that you do this unless you know exactly what you are doing.
My next step is to call verizon and say they need to get out here and fix this ** or I will be going back to comcast.
Verizon has nothing to do with the Time Capsule problems that you have encountered. Blaming them will accomplish nothing.

Help with time capsule issues please

Hi all
Any help or advise will be greatly appreciated.
I will give you a little background info as it may be relevant.
At home we had 2 MacBook pro's that backed up to a 2tb time capsule all worked well, wifi and back ups. Unfortunately both MacBooks where in boot/trunck of the car while we where traveling and the boot had a terrible leak that I was unaware of and both MacBooks where water damaged tried drying them out but both where beyond repair. (Devastation is not the word especially as the car insurance would not pay out)
Unable to replace both MacBooks We continued to use the time capsule as a wireless router for both our iPhones then after 6 months or so the Internet would go off and the orange flashing light would come on. I just thought it needed reset and so switched it off and back on. Sure enough green light and all is well this became more and more frequently until the orange light stayed on regardless of what I do with no Internet. I've connected an old router which is working fine.
The good news is that after a year without a MacBook I have a new one arriving tommorow. My main concern is the data on the TC I don't want to loose it but i don't know what to do?
These are my options as I see it but again any suggestion welcome.
1)I unpack the new MacBook pro set it up as normal then connect to the TC and check airport utility and hopefully this will tell me it just needs a firmware update. Install the update for TC reboot and check the green light is on, then to a fresh install for the mac and re-install the MacBook from the TC.
2) when booting up the new MacBook try and find the TC when it asks for it and hope all goes well and it transfers my old MacBook data onto my new one.
As I say any help or advise would be greatly appreciated, please note my primary concern is not loosing the data on the TC from my old MacBook
Thanks for all the replys in advance

It sounds like your TC has become unreliable.. is it a series 1?
You might need to get it repaired, as it can take several hours to get the backups off the drive.
Check in UK for local repairers.
https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repairers
It is just the power supply gone faulty and repair or replacement should get it going again. The data stored on the hard drive should be ok. Restoring the files from the old TM should be ok.
The instructions here are extremely helpful for how to recover particular files. As your new laptop will be Lion and you don't want to recover the old OS.. just the various files you had stored.

Help with Time Capsule/wireless network setup

Just purchased Time Capsule, hooked it up, and followed the instructions to create a new wireless network. The problem is that my MacBook Pro can't find the internet via the new Time Capsule network. It can "see" the Time Capsule, and I can log on with the new password, but there is no internet connectivity. If I unhook the ethernet cable from the Time Capsule and hook it directly into the computer, the computer is able to rapidly access the internet. Plug the ethernet back into the Time Capsule, and even though the Time Capsule light is green, there is no internet connectivity for that computer or other computers. Also, the Time Capsule signal strength is exceedingly low. Help!

Please try the steps again. However, this time, I would like for you to perform a modem reset between powering all the equipment down and starting to power them back up again.
You should find a reset button on the back of your Motorola modem.
So, the steps should now be:
o Power-down all of the equipment, except the modem.
o Perform the modem reset. Note, the reset may take anywhere from 5 to 30 minutes to complete. Check your User's Guide that came with the modem. If you don't have a copy of the guide, you can get it here: SB5101 User Guide
o Once the reset is complete, power-up the TC by following the sequence I provided earlier.

Help with Time Capsule remote access

I have recently purchased a MacBook Pro and a Time Capsule. I have registered with a MobileMe account and have specified the details of this in the Advanced section of AirPort utility. However, I don't know what else I need to do to enable me to access the Time Capsule remotely? The Time Capsule is set up on a bridge with my existing router and is performing backups, so I believe that this is working as it should. Any advice would be much appreciated as I'm new to Macs! Many thanks.

Hello morph1977. Welcome to the Apple Discussions!
I believe the issue is that you have the Time Capsule (TC) behind another router.
I assume that you want to take advantage of BacktoMyMac (BTMM) to access the TC with your MobileMe account ... correct?
If so, two things must be present in order for BTMM to be successful: 1) Routers on both ends of the connection must support either UPnP or NAT-PMP. Note: The AirPort and TC both support NAT-PMP, and 2) The router with the host device you are trying to reach must have a publicly reachable IP address.
BTMM only works with either a public IP address or with automated port mapping via NAT-PMP or UPnP.
Here's roughly how BTMM works:
1. For a computer connected to the Internet via a router that assigns it a network address, BTMM asks the router for configuration information.
2. BTMM sends this information to MobileMe: BTMM tells MobileMe where the computer is located and how to reach it on the network or via the Internet. This information is stored on the MobileMe’s servers.
3. When connecting to a remote computer, your copy of BTMM creates a secure connection with the other computer, using the information about that computer’s
location and configuration stored on MobileMe.
Since the TC is behind another router and configured as a bridge, the only thing that needs to be configured on it is to identify the MobileMe account(s) that will access it using the AirPort Utility. The key would be to make sure that existing router has either NAT-PMP or UPnP enabled.

Help with time capsule!!! wireless connection to router!! HELP!

Wondering if anyone know if the time capsule could connect wireless to my router? Got a PC on the second floor. Anyone know if I could connect through time capsule with cable to my PC and have the internet wireless with the time capsule?? Help please!! Thanks!

The answer is no.. sorry.
Apple made the TC and Extreme unable to do wireless bridge.. unless you have another Apple router that is creating the wireless connection. The Express is the one odd one out.. it can do it.
You can buy a standard PC type wireless bridge fairly cheap but I would still be careful.. buy something that matches the main router and can use WDS.. try not to get onto the universal wireless repeater bridge bandwagon.. it is often not reliable.

Help with Time Capsule with a new modem

Hi,
I did a search and couldn't find what I'm looking for. What is the easiest way to setup my Time capsule with a new modem? I will be using wifi with the time capsule. I just got a new modem and the time capsule keeps flashing a amber light. It was working off wifi before I got the new modem.
Thanks, Jerry

There is only one right value for wireless now. Which I did list in the instructions.
WPA2-PSK (AES) for the arris.
WPA2-Personal for the TC.
Did you reboot everything when you disconnected the ethernet.. so the computer and TC can reallocate the IP addresses. This is important.
Reboot everything when you rearrange networks.. always do it.. even I am forced to do it.
Reboot in this order.. from off.. everything off.
Modem.. wait 2min
TC.. wait 2min
Computer.. this will now pick up a new IP from the whichever wireless is stronger.. should not make any difference if it is the TC or the Arris.
Now see if the TC is available in airport utility.
If it fails .. reconnect it by ethernet to the computer.
Give it a different wireless name .. ie the Arris and the TC will have different names.
And you are using "create a wireless network" in the TC.. no other option will work.
Update the TC so the setup is saved.
Unplug the TC from the computer and plug it into the Arris..
Now reboot everything.. sorry.. but it is the easiest way to clear up old settings and get everything going again.
Now in the computer you will need to open the airport and find the TC wireless.. and then you connect to it.
Once you connect direct to the TC you should have no trouble.
You can setup and fix any issues.. there are always a few silly things.. password default or wan setup .. choose ignore or change settings.

Creating Two Networks with Different Securities and Double NAT Error

I have a Time Capsule which is connected to my cable modem and an AirPort Extreme connected to my Time Capsule via the WAN port. I configured the AEBS to create a wireless network using WEP (I have a few devices that don't support WPA) so I can use two different wireless securities. The AEBS flashes the amber light and once I connect to its network, the AirPort Utility states that it has a "Double NAT" issue. I used my iPhone 5 to connect to the AEBS network and I can access the Internet just fine.
Is this issue one that can be resolved? If so, how? Or do I ignore the issue? If I ignore, what are the implications?
Thanks!

You need to configure the AEBS in Bridge Mode to eliminate the Double NAT error, which is slowing down your connection...and may likely cause other issues depending on how the network is configured.
If you do not know how to do this, we need to know what operating system you are using on the computer that is being used to configure and setup the AEBS.

When doing a restore with Time Capsule, I get -8003 error; restoring nothing

Hi,
When doing a full restore with Time Capsule, I get -8003 error; restoring nothing. This happens with all recent backups. Also after doing a verify/repair of the TimeCapsule disk.
This is a dissaster for my originals (my Ableton Live projects). I am very dissapointed in TC and TM at this moment, because I trusted my backup system in combination with my MBP fully.
Please help?
Best regards, Tom

Hi Pondini,
Sorry for the late response, but the problem was something else and were two separate ones.
Somewhere along the way the TC backup couldn't find backup to the original TC volume, that's why I let TM backup towards my user volume named 'Tom'.
When I wanted to restore the root of my drive when selecting the diskname and 'Restore' in any point in time, this resulted in error -8003 in the activated TimeMachine.
Then I tried to do it via the recovery OS and even via the original OSX DVD. Both not enabling me to select the TC volume named 'Tom'. Then I remembered that I first backed-up onto the original 'TimeCapsule' volume/partition. When I copied the sparsefile to the 'TimeCapsule' partition, I was able to recover the entire disk using the recovery OS.
All my files are backup and I am a happy Mac user once again :-)
Thanks & Regards, Tom

Double NAT Error with Airport Extreme and Airport Express

I have an Airport Extreme 802.11n base station which is connected to my DSL Modem/ Router via Ethernet. I have a MacPro which does not have an airport card installed so I bought an Airport Express 802.11n - which is connected to my MacPro via ethernet - and thus provides my MacPro with internet access.
Originally I had the APExtreme and the APExpress set up in a WDS - all worked well - my other wifi equipped macs and devices in the house connected to the network with no problem, but I did notice that the maximum throughput I was getting was 802.11g speeds - this is of course due to the overhead of the WDS.
I originally purchased these 802.11n devices because I wanted the higher throughput - so I decided to terminate the WDS and just have the APExpress (attached to my MacPro) "join" the wireless network instead of extending it - which works and I am enjoying the 802.11n speed.
So, I just upgraded a couple of my Macs to 10.6.2 and was going to start using "Back to My Mac" and I got the error that there is a double NAT address problem and that "Back to My Mac" won't work until this is resolved.
I know that going back to a WDS will resolve the double NAT problem - but I don't want to take the performance hit that goes with the WDS.
So, short of buying an Airport card for my MacPro (which would eliminate the need of the APExpress)
Is there any other way to resolve this double NAT problem besides WDS?
Thanks for any advice.

First of all thanks for your quick reply!
Connecting my MacPro to the Airport Extreme would be a serious pain as the DSL Modem and APExtreme are upstairs near the only connection point in the building to a phone line - and my MacPro is downstairs.
I suppose I could dig out a very long ethernet cable to perform the test. But before I jump through that hoop - please explain to me what you are trying to get at - in other words - what does it mean if this resolves the double nat error - and what does it mean if it does not?

HT2497 Why does my Airport Utility keep saying "Double NAT"error?

I had to add a new cable modem to my home network.
I keep getting a "Double NAT" error and my modem keeps the yellow light blinking.
What do I do?

It's almost a miracle that it was working at all.
Each wall will absorb on average, about 15-20% of the signal so after 4 walls...and a ceiling....which is typically 2-3 time thicker than a wall....there isn't going to much signal left to extend.
Try locating the Express no more than half the distance between the Time Capsule and the general area upstairs that needs more wireless coverage. Minimize obstructions in the signal path as much as possible.
If that does not help, we'll have to do some SNR measurements to see if what you are trying to do is even feasible.

Modem/Router to use with Time Capsule

Hi forum,
I would like to work around a DOUBLE-NAT problem that I am encountering in my business network.
Currently, my ADSL modem/router is an Orange Livebox which creates its own internal network (192.168.1.x).
My Time Capsule is connected through ethernet to this LiveBox in DHCP/NAT mode. It creates a second internal network (10.0.1.x). All the rest of the network equipment is attached wirelessly or by ethernet to the TC network. My goal is to manage the network (ports, dhcp addresses, etc.) through my Time Capsule, not through the Livebox. That is why I configured TC in DHCP/NAT mode.
The downside is that it creates a Double-Nat problem, because each packet is going through both networks (192.168.x.x and 10.0.x.x). Lately, Apple Support is telling me that this Double-Nat issue could be the cause for failing to answer iPhone calls directly from my MacBook Pro (new feature of Yosemite) when connected in my business network, where it works perfectly when connected from home in where there is no Double-Nat issue.
I contacted Orange Livebox technical support and asked wether it was possible to de-activate the router portion of the Livebox, at least the DHCP/NAT portion of the box since I would not mind to keep the built-in firewall of the box. But the answer was no. It looks like I cannot turn off the router portion of the Livebox at all, so my only solution for them is to enable the bridge mode on TC, which I still don't want.
I was told to buy a ADSL2 modem and replace my Livebox with it, so TC would effectively become the only router on the network. That looks to me like a satisfying solution (at least on paper).
Would any of you know and recommend a particular brand/model to work with Time Capsule. Ideally, what i would like this modem/router to do is :
Modem part: connect with my provider in ADSL2 and provides my credential to establish the connection
Router part:
DHCP/NAT = OFF
built-in firewall = ON
I assume it would be the best way to get the best of my Time Capsule (802.11n - 3rd Gen).
Thanks for your help or advices on the matter,
Lanceloz

I believe I followed your structure step by step. And here is what I got (see attached files). Hence my question about the TC hardware and software version that you are using.
