• LRT214 - OpenVPN - unable to connect

  So, I've spent the last two days trying to get OpenVpn to work with zero success. I started by following the tutorial, exactly as the manual says. I export the configuration file and load it on a different device on a different network and attempt to connect, but with zero success.

  After that I tried to play with different ports with zero success. I tried UDP and TCP with zero success. I added rules to allow traffic on these ports with zero success.

  When I say zero success, it is not entirely true. I can't get a connection. But from time to time I find a setting that will produces a log of SSL on the LRT214 which gives me: SIGTERM [hard], received, treat out.

  On the client side my logs are back with this for TCP: the system tried to join a drive to a directory on a joined drive.

  and for UDP, I get: TLS error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity.

  I know that I can talk to my router because I install a simple PPTP VPN and it worked perfectly, but OpenVPN, not so much.

  Any ideas or comments would be great to help me understand this!

  Thank you!

  So after having a great revolution at the wheel, I understood the question. I feel almost stupid to do this.

  For my xBox, I have forwarded port all traffic to reach NAT open to all the games that I play. List could as long for port transmits all.

  This caused any request to connect to the router via OpenVPN, because the router will be sent directly to the release of the xBox. I had added a rule for the port forward just the port OpenVPN for the router itself, but it did not work at first, because the router takes the list of ports to the front in order that it was created in. To solve the problem, so I 1194 TCP forwarded to the IP of the router, then any traffic thereupon forwarded to the xBox.

  Not sure what the best way to handle this, but it's the solution, I came to the top with for now. Looking to hear for the best solutions.

  Now, my next issue is that after the Split Tunnel connection, I cannot ping any computer in the network, nor can I ping the remote client.

  Ideas or suggestions on this?

• Problem: Local with OpenVPN network Mode

  Hello everyone.

  I have a problem on the Local Mode with OpenVPN network.

  My VM is a domain system based that needs a connection to the domain and redirects to files.

  This virtual machine works very well in online mode. It's good for the execution of this virtual machine in local mode in my company.

  One day, I get out of my company and use OpenVPN to connect back. I find that I have a problem.

  After that I started my VM, I realized that the VM network is link to my REAL, not the one OpenVPN network. It cannot connect to the DC of my company. The IP address of this virtual machine is DHCP on my network REAL, not the VPN server.

  Is it possible to fix it?

  Thank you.

  What is interesting.

  Default local mode works in NAT mode, so if the host machine is connected to a virtual private network, the guest running in client Mode Local should also see this network.

  Couple of clarifying questions then we can dig deeper:

  1. Any chance, the system has been reconfigured in mode bridged force instead?  (there are registry/GPO settings for this)
  2. Where is made the VPN connection?  Before or after that the VM Mode is turned on?
  3. The VM really not accessing the VPN network or is it just failing to get DNS information, (for example if you have the full IP address of a machine that is accessible through the VPN, can you ping that even if you cannot resolve the name?
  4. If the VPN connection is made after the virtual machine is running, have you tried the experience of first manufacturing of the VPN connection, and then start the virtual machine?

  I ask #2, #3 and #4 because the NAT daemon can sometimes be a little less sensitive to the host networking changes you want - especially regarding the DNS lookups.  You can also experiment with restarting the VMware NAT service on the host once the VPN connection is made to determine whether giving it the kick it needs.

• 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.

• iOS10 openVPN

  I have been using openVPN on the iPhone for a long time with 8 and 9 of iOS iOS. There is no problem. Today I updated the phone to iOS 10. After that the openVPN app no longer works. I can move the slide, switch to green color changes, but nothing else. There are no new line in the newspaper. It displays "Disconnected", and that's all.

  There is no difference if the phone is connected to the internet through WLAN or LTE. In Safari, the web browser, I can open web pages without problem.

  What could I do? Could someone help?

  OpenVPN uses PPTP Protocol by chance? PPTP is no longer supported in iOS 10. You must use other VPN protocols.

• 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.

• Why Firefox do not connect to Web sites more after that I made a connection with OpenVPN?

  IE has the same problem. UTorrent still working after I connect with OpenVPN.
  I am running XP Professional SP 3.

  During the OpenVPN connection I ping google.com. It does not work. When I ping the IP (instead of name) from google.com I get respons.

  By the time I disconnect my connection OpenVPN Firefox work again as usual

  This is a guess, but: do your TCP/IP in Windows settings specify a particular DNS server? If so, you may need to clear that if DNS servers can be defined by the proxy service.

• 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?

• 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.

• no connection possible outgoing openvpn

  Recently, I replaced an old router with a time capsule Airport (version 7.7.3) (and in another room with an airport express).

  Since this installation, I am not able to connect to openVPN in the work of the office. There is no problem if I use my old wifi or my IPhone as a personal hotspot.

  When you try to use openvpn I'm always connected to the time capsule Airport (in which case it's interesting)

  Research on 'internet' gives no useful result of which could be underway, so any help is appreciated.

  I forgot to mention (quite probably important):

  -It connects to the VPN that is identical to the work situation

  -I can ping the virtual private network addresses

  -No other "traffic" as possible (ssh, http, https, etc.). Symptom is that it blocks just forever (ssh) or charges for always (web page).

  -J' use tunnelblick

  Such things can sometimes be an MTU problem. See https://groups.google.com/forum/#! topic/tunnelblick-discuss/ttvriICTZV0.

  Another possibility is a DNS problem. The value Tunnelblick (one) route by the VPN and (B) check if IP address of changes (both are in the window "Details of VPN" Tunnelblick 3.6beta20). Wait at least 90 seconds after the connection, and then look in the Tunnelblick journal for a message on the IP address change. (The change of IP address tries to contact tunnelblick.net through its name, and if that fails, by its IP address, so it may help in diagnosing the problems of routing DNS issues).

• 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.
