• How can I change the base station Airport of NAT mode?

  I'm trying to set up an Airport base station and stuck because I have the following message is displayed, but no idea how do what he asks...

  Status is showing as Double NAT and then asking me to move on to the base station in bridge DHCP/NAT mode.

  But where do I do this?

  Thank you

  It can be difficult to get the router to bridge sometimes... but if all goes well... Click on the airport icon in airport utility and then click on edit.

  

  Go to the network tab and change DHCP and NAT to bridge.

  

  Click Update at the bottom of the page... Then, everything should be good.

  If you are having problems follow these steps.

  Reset factory airport and then do a manual installation. I recommend that you connect with ethernet which is much more reliable, but your MBPr is not the most important network port that exists... Although there is a bolt of lightning at low cost for the ethernet card.

• The settings DHCP Airport extreme & NAT - cannot change default of NAT IPs?

  Hello

  I'm trying to configure Airport extreme, the most convenient to use for our office.

  Our Office IP is 10.255.x.x

  When I'm trying to Setup DHCP and NAT, in NAT options, there is only 10.0.x.x, 172.16.x.x and 192.168.x.x

  How can I get NAT to have 10.255.x.x?

  Without the NAT settings, I can not get this Airport Extreme to assign valid IP addresses and so unnecessary

  Sorry, but Apple will only accept the 10.0.x.x addresses to be assigned by the AirPort Extreme.

• NAT with Snow Leopard issue

  For the poster who will say "Google is your friend", no it is not, or I wouldn't be here.

  I tried for a while now to solve the only problem I have with Snow Leopard Server.

  MySql has fallen lion and, apparently, no one knows how to use postgrl so I installed MySql and plundered with her for a few hours to get this working.  There were various other issues with Lion.  Finally, I went to Yosemite.  Hey Apple, where is the GUI?  Then at el Capitan and finally tried Sierra (no server app at all yet).

  For me, each 'step-up' taking things and running weaker than the last.

  Welcome to Snow Leopard.  I'll stick with it for a while to come.

  The only problem I have with Snow Leopard, it's that when it restarts, the NAT will not start upward.  Other than that, it does a magnificent job to maintain my home network.  I searched high and low for an answer without success.  A few posters who have addressed this problem specifically here never got a response.

  As this seems to be about three years or more, since this question was asked and it seems that some have migrated to the SLS, I was wondering if anyone has found a solution.

  As it is now, as soon as there is a need to reboot, I just disable the NAT service, restart and turn it back on.  In the case of a failure of current (longer than the inverter can maintain) or just a random crash, I have to kill the firewall and NAT then the configuration of the gateway of new service that requires fixing the various omissions and errors and I'm good to go again.

  Any help would be greatly appreciated.

  You have posted in the forum of Snow Leopard Client.  I ask that to move this post.  In the meantime, you can see the various forums about this trick:

• Garage double NAT & DHCP - bridge Possible issue error

  Help...

  So it's my game on a yacht...

  I have a MacMini (run bootcamp Windows 7 Pro), so actually it's a PC.

  • I use internal WiFi adapter of the MacMini to get my internet connection of various different Marina I could stay in
  • I then share the connection with the internal LAN adapter WiFi adapter WiFi
  • This allows me to share the WiFi port with other devices on the yacht

  Then I have an AirPort Extreme-

  • I then run an Ethernet on the MacMini Port CAT6 cable
  • on port WAN on AirPort Extreme
  • AirPort Extreme now has an internet connection (from the marina, WiFi)
  • I then activated the WiFi on AirPort Extreme to create a WiFi network on the yacht
  • and it gets its internet connection from the WAN port, which comes in turn the MacMini, which in turn comes from the Marina WiFi

  Connected to the AirPort Extreme are-

  -iPhones, iPads, MacBook, Apple TV, Smart TV, etc etc.

  -Some devices are connected using the LAN ports and AirPort Extreme cable

  -Some devices are connected by WiFi using WiFi airports

  I want DHCP to be handled by the AirPort Extreme-, mode I set as "DHCP and NAT".

  What is the problem-

  • AirPort Extreme shows an error
  • "double NAT and DHCP.
  • and suggested I turn it in Bridge mode
  • but I don't want to do that

  Any thoughts?

  Concerning

  Tim

  Would help if we could get the exact message you see.  You will probably need to change the DHCP-range on the AirPort Extreme to a different value, and then use the option 'Ignore' the Double NAT then the airport will show a green light.

  You will have to live with the Double NAT if you want AirPort Extreme to act as a remote router that provides a private network.

• Strange double NAT, although there is only a single router

  My ISP (RCN) changed my modem at a speed greater than one.  Although a router built-in, I told them that I didn't use their router, only my Time Capsule, so they disabled.  However, my Time Capsule kept gives me an error message Double NAT and amber flashing against Green, even though everything seemed to work (wireless and wired) and said that I should switch DHCP and NAT to bridge mode.  Correction of the error, but I do not understand what caused the Double NAT if there is only a single router.  The ISP Technical Support people confirmed their control center is not the router feature on in the new modem, I ask.  They also said that their network supports DHCP, although they have other who use the Bridge Mode, although they do not support.   And they knew nothing about it, he said to ask Apple.  They also offered to switch back, but because this modem is faster at the same price.  (He called a bypass gateway 3-in-1).  Many people online told not to use his router, it's why I unplug it and only use the time Capsule.

  So if someone can give me feedback, I'd appreciate it. I must:

  1. keep running the new modem and my Time Capsule in Bridge Mode.

  2. run the new modem in DHCP mode, as they put in place and do not worry Time Capsule seeing amber / flashing Double NAT error.

  3 swap back to the previous modem, which was 50 Mbps against it with (theoretically) 155 Mbit/s (it's only works in 50-70).

  I'm not really all that, but I hope that one of you maybe.  Thank you!!!

  Although a router built-in, I told them that I didn't use their router, only my Time Capsule, so they disabled.

  ISPS often make the mistake of simply turn off the radio on a modem/router...which service does not disable the router function of the device. You still have a wired router when ISPS are making this mistake.

  However, my Time Capsule kept giving me an error message Double NAT

  This confirms again that the ISP has not disabled the function of the router to your modem/router.  On some modems/routers or gateways, it is not possible to get the device to act as a simple modem.

  The ISP Technical Support people confirmed their control center is not the router feature on in the new modem, I ask.

  The fact remains that you wouldn't see a Double NAT error unless the ISP system acted as a router... Despite what people of PSI say. You may need to get a 2nd or 3rd person-level support, who knows what they are doing.

  1. keep running the new modem and my Time Capsule in Bridge Mode.

  Yes, if you want to avoid the mistake of NAT Double... what you are doing. But, the time Capsule will not be your router.  The device of the ISP will be.

  2. run the new modem in DHCP mode, as they put in place and do not worry Time Capsule seeing amber / flashing Double NAT error.

  This only if you willing to accept the fact that the ISP did not correctly change your gateway to make it work as a simple modem only.  You might be able to get away with a Double NAT error on a simple network, but there is no reason more complicate things with a misconfiguration in unless whether there are a few reasons to do it and it can't be avoided.

  3 swap back to the previous modem, which was 50 Mbps against it with (theoretically) 155 Mbit/s (it's only works in 50-70).

  Your decision if you want to run a simple modem with time Capsule, or accept the fact that the time Capsule won't have your router when it is configured in Bridge Mode, or you see a Double NAT error on the network.

  If it were me, I would go back to what I know will work properly... the simple modem and time Capsule as the router.

• How can I enable UPnP (Universal Plug and Play) or NAT - PMP (NAT Port Mapping Protocol) Protocol?

  I'm trying to set up the screen Edovia and they say that I need to enable UPnP (Universal Plug and Play) or NAT - PMP (NAT Port Mapping Protocol) Protocol.

  How can I do this?

  In Airport utility. The form is in your router.

• Types of NAT and security

  Question: What should I do to get the NAT on my PlayStation 1 type while keeping the type NAT 2 on my other devices?

  Hello! I connected an AirPort Express into my modem. The AirPort Express gives me type NAT 2 on my units, which is good. However, my PlayStation 4 has a lot of problems connecting to games online with this NAT type. I would get the type of NAT 1 on my PlayStation, while keeping type NAT 2 on the rest of my devices for security reasons.

  The two options I can imagine are the following:

  1. Changing the type of PlayStations NAT without compromising the security of other devices is directly connect the PlayStation to the modem with an ethernet cable. Again, I would not a cable through half of my house, and so I would like to know if there are other options.
  2. Buy a new separate router and have two totally airtight networks, then use port forwarding to get NAT type 1 on one of the routers.

  Change the NAT type to open (1) for all devices is not an option, because it will change the security settings.

  Please see the following Tip of an airport users for more details on the types of NAT for PS 3/4 consoles with AirPort base stations.

• Time Warner failure: replace BRIDGE MODE DHCP/NAT!

  If I woke up this morning to find that my Time Warner Cable internet has exploded the line last night. According to my AirPort Utility application, my Airport was functioning normally, but it was not connected to the Internet. So I restarted the thought of the airport that could solve. Not only it does not solve my problem, it made it worse:

  Now, he pointed out that the AirPort base station has a private IP address and suggest that change my Airport to use DHCP and NAT mode.

  Now keep in mind, it has been working perfectly for months with the current settings. Suddenly, he must be in Bridge mode after reboot it?

  I had to leave for work so I didn't have the time to reset the modem from Time Warner Cable. However, I suppose that I should not change the settings on my AirPort at the moment since it worked perfectly before?

  I have the current model AirPort Extreme and configured automatically, after several attempts of frustrating with the same modem from Time Warner Cable, which I am currently using, of course it takes hours to acquire a signal of Time Warner Cable.  It has been working perfectly since.

  This should resolve on its own once the cable connection is restored, or is it that this means that I have to completely reset my AirPort Extreme and implemented from scratch with the cable modem I did originally?

  It would help us if you could provide the serial number and model of your modem.

  IF... the modem normally gives you a public IP... so the parameter DHCP and NAT on the most convenient airport would be correct.

  IF... the modem... which normally provides a public IP address was not reset, then it could actually send a 'private' IP address... probably something in the 192.168.x.x range... that is not correct.

  Turning off the modem by pulling on the power cord to the back of the unit

  Unplug the co - ax cable and Ethernet cable

  Let off for at least 30 minutes the modem... 60 would be better.

  Turning off AirPort Extreme as well

  After turn off modem, reconnect things

  Start the modem and let it run for at least 10 minutes by itself

  Then, turn on the AirPort Extreme.

• FVS336Gv3 multi-NAT inbound firewall rules does not

  I have about 30 Netgear FVS338 and a few FVS336Gv2 routers in use. I use for firewall and provide multi-NAT between industrial machines and WAN. The configuration was changed on Gv3 models and I can't get an answer behind the firewall or router in the diagnostics page when you use the WAN address.

  In the examples below the WAN is 10.62.

  

  Figure 1. Two different devices with two different configuration options.

  

  Figures 2 and 3. The first is bad - it would only connect from this address. Have I set up another correctly to the NAT WAN to LAN 10.3.110.215 address 10.62.31.55 address?

  Q1: Is Figure 3 configured correctly?

  Q2: Why is it forcing me to create a range of addresses? On the older routers, I had the opportunity to address.

  Q3: Is anyone aware of any problem with this router?

  For anyone having the same problem, the FVS336Gv3 requires the manual addition of each new address WAN-side. He is buried in the menu structure:

  

  Figure 1. Network configuration | WAN settings | WAN configuration. WAN1 - Edit.

  

  Figure 2. Select the secondary addresses.

  

  Figure 3. Add the required WAN addresses.

  Now configure the inbound firewall rules:

  

  Figure 4. Security | Firewall rules. Add or change. Note that the WAN secondary addresses are available in the drop-down list address WAN IP.

  Password

  There seems to be a problem with this router about the session timeout. I got them several times on the navigation menu and log on again and renavigate. Idle time-out is set to 90 minutes. I never saw this problem on routers earlier.

  Also, note that the password field now has a limited character set. for example, it does not accept ' $'.

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

  Hello

  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.

• NAT Loopback: Low broadband bandwidth

  Hello

  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.

• One-to-one rules NAT?

  Can someone help me get my head around how to configure my firewall to put rules in place "Univocal" NAT?

  I have a block of static IP addresses with our ISP. I am using two of them. One for our front door and another for our server SBS2011 hosting Exchange, OWA, etc... I'm looking to replace our Linksys RV082 with a UTM9s I have for assessment. On the Linksys, it's a simple box and a line of text and you're done. All of our web traffic appears to come from our gateway address and the mail is sent to and seems to come from the address of our server. How to configure the UTM9s to achieve the same thing?

  / 29 blocked IP addresses:
  ... 74<>
  ... 73
  ... 72
  ... 71
  ... 70
  ... 69<-sbs2011, mail.domain.com,="" mx,="" ptr,="">

  I think I'm pretty clear on how to configure inbound rules, but technical support mentioned so the outbound rules. Unfortunately, he didn't much further to add.

  I am currently waiting for a replacement UTM9s arrive, the first was DOA. I must say that those who thought it was a good idea to require an internet connection just updating the firmware should be expelled in the nuts.

  Help, please.

  I actually just thought of it. The Barracuda service that I could replace it with the UTM was sent to the adresse.74 not le.69. The RV082 he let fly, the UTM would not.

  Thank you for your help.

• Airport Extreme Double NAT / AT &amp; T NVG510

  My Internet connection has worked very well for several years, until recently, when the simple DSL modem (a Motorola 2210-02 - 1ATT) provided by AT & T began to experience intermittent outages. Initially, the DSL modem would lose the line for a minute or two at a time. But within 48 hours, the line started to drop during the hours in a row (synchronization failed line DSL). Whenever the modem has lost the line, my Airport Extreme (the router on my home network), shows a "Double NAT" alert. But whenever the modem 2210-02 DSL connection has been restored, alert the Airport Extreme's "Double NAT" disappeared.

  After a day and a half problems, the line is down for so many hours that I finally called AT & T to check the status of our range. So, AT & T sent a technician who concluded fairly quickly the 2210-02-1ATT was the problem and replaced it with a modem/router combo (manufacturing date 11/2014) NVG510 (with router function disabled in the settings).

  The speed that results and the quality of the connection via the NVG510 were good, so the tech packed 2210-02 in his bag and left. But now I get that alert "Double NAT" once again on my Airport Extreme, even if the home network is apparently working as well as it ever did.

  The only setting I changed was on the NVG510 - as soon as the technology has left, I turned off the WiFi on the NVG510 function because I want the Airport Extreme to my router, same as always.

  So far so good. After 24 hours with the NVG510 in place, the network worked well with no major hiccups, the only exception being the status of "Double NAT" alert displayed in Airport utility. In fact, had I have not bothered to watch Airport utility, I don't know that there was a "Double NAT" alert

  Everything on the side of the NVG510 LAN is identical to what was in place with the 2210-02...

  Airport Extreme 802.11ac works as "router" with the WiFi signal on another floor via an Airport Extreme 802.11n wireless (5th generation).

  The WiFi signal provides web access to some desktop Mac, AppleTV, devices, mobile phones, tablet computers and a laptop (laptop is the only device that uses a VPN).

  The network on the Airport Express 802.11ac, who serves as router, is "DHCP and NAT." and the "5th Gen," which extends the wireless network, set mode "bridge."

  After hours of searching online, I understand that this problem is surely the result of the NVG510, and that this problem exists for at least five years. I've read at least a few tens of different ways to try a fix via adjustments to settings, but none reached the level of a real solution.

  Although my network is no problem at the moment, I'm afraid that "Double NAT" alert is a sword of Damocles that will eventually crash my network, a situation I like to avoid. I dared not yet connect the laptop with a VPN to the router, but out of fear that will bring down the whole network.

  I'd rather solve the "Double NAT" proactively.

  Is there a a way to eliminate the Double "Nat" by adjusting the parameters of the NVG510 and/or the Airport Extreme?  Or, my fears of future problems and a VPN disaster are unfounded?

  Thank you

  According to your comments, the NVG510 has not been reconfigured as a bridge and is providing routing functions (NAT & DHCP).

  To resolve the Double NAT is the new Motorola NVG510 or AirPort Extreme needs to be reconfigured under a bridge. The simplest solution would be to reconfigure the extreme. In this way, the NVG510 can handle NAT & DHCP services required by clients of network connected to the extreme to access the Internet.

  To reconfigure the extreme as a gateway, use the AirPort Utility, as follows:

  • Run the AirPort Utility and then select the extreme.
  • Click on Extreme and then, select Edit.
  • Click the network tab to select it.
  • Change the router Mode to: Off (bridge Mode)
  • Click on update and allow extreme restart.

• Double error NAT with Ooma

  I use a time for Backup Capsule and WIFI. I have a cable box to receive Internet.

  I am positioning the Ooma telo between the internet modem and TC box.

  It works, BUT I have a flashing yellow light of TC. I guess that's a double NAT error.

  I know that to go to the wireless utility but you choose DHCP only or bridge?

  If so, should I put a static IP address... If Yes, how should I do this?

  If someone here could provide simple step by step instructions... the above may SEEM like I know what I got kindof... but I don't.

  Thank you.

  Are you still using OS X (10.6.8)... as you indicate in your profile?

  If this is not the case, what operating system are you using right now?

• FVS336GV2 Nat or routing?

  I'm trying to secure our home network a little more until it gets 'tested '.

  I understand NAT, and routing. What I do not understand how the FVS336GV2 can do without NAT routing or if that's what he does.

  On my network - Mode WAN Configuration, I can choose "use NAT or classic routing between WAN & LAN interfaces?"

  What "Classic routing" done differently and it's better than NAT?

  I have Google had this, and found a lot of things on the hardware vs NAT and firewalls and software and more, but nothing as compared to NAT vs routing in the same device...

  I'm not sure you understand NAT or why it is necessary.

  Answer this question - do you need to share a single public ip address between several devices - or in the case of a double router WAN as the FVS336G, two public ip addresses?

  If the answer is Yes, then the classic routing isn't an option, you MUST use NAT, and you are likely to see a comparison between the two - they consider mutually exclusive options, which do different things.

  If you used the FVS336 as a router classic connected to the internet (and Yes, you can use this way), you need a public routable ip address for all devices on its LAN interface
