10.9.2 VPN disconnects constantly

I updated from 10.9.1 to 10.9.2 and ever since I did, VPN loses connectivity constantly. It says that it's still connected, but the traffic through the VPN fails. I lose connectivity to the file server and I can't access websites on the same IP cluster as the file server. I have to disconnect the VPN service and reconnect about 8 times a day.
I thought that 10.9.2 was supposed to solve VPN problems, not cause them. Any ideas?
One additional note: VPN on Windows on the same local area network does not have this problem.

Nobody has any ideas on this?
One other piece of information: In the Network system preferences, I can't access the Advanced options for VPN. When I click the Advanced... button, it just gives me two options: DNS and Proxies. None of the settings shown in Apple's support document are available:

Strange Behavior: VPN disconnects silently while Podcast Cellular Data status is notified continuously

I would like to know why the built-in VPN disconnects silently without notice, which is a potential security issue.
Especially, when I am reminded continuously via a prompt, that prevents any further use of the system until acknowledged, when Podcasts or Music is run with: Cellular Data is Turned Off for "Podcasts"
I would expect the VPN to at least notify when disconnected.

VPN disconnects

We have a wireless network in our house. I connect to the internet and then connect to my company's VPN. However I get disconnected from the VPN constantly and it says the connection was terminated locally. I have to disconnect my linksys connection, then reconnect, then connect again to the vpn. Do you have any idea why my connection keeps getting broken. I often wonder if once I get connected to the VPN and if I am not out on the internet moving around if it times out or something. But it is rediculous because sometimes I get disconnected as quickly as 2 or 4 minutes. Othertimes it is an hour

What kind of VPN? IPSEC? SSL? If it's IPSEC and you can use SSL try that instead. It's a little less secure but more stable. Also check with your VPN to verify whether you need to punch a few holes in your FW. Ports 47, 50, 500, 1723, 5050 are all candidates.

T500 Windows 7 blue screen on VPN disconnect

Brand new T500 came with Win7 preinstalled. Machine is connected to a Windows domain at work, and I VPN into various clients' networks. Often (not always) when I disconnect the standard Microsoft VPN, the screen goes black, and I see the disk active for less than one minute, and then the system is hung - no response to mouse, ctl-alt-del, etc.. I power down by holding down the power button, then power up. Windows reports recovering from a bluescreen. I have already used ThinkVantage System Update to load the latest drivers for everything.
Any ideas?

The same problem to me T500 Win7 64 bits 4GB RAM. 2 or 3 time weekly the laptop is accidently stop working with black screen, strange noise and for a while hard drive activity. If somebody knows the solution of this problem will be very good I updated the BIOS and every kind of driver updates but no changes. There still persist the problem.

My Skype is disconnecting constantly

My Skype keeps disconnecting for short amounts of time (like maybe 30 seconds) and then reconnects. It does this constantly though. It happens at least every 5 minutes (sometimes even every 2 minutes) when it is at its worst. I have tried searching for an answer but nothing seems to be working. I reinstalled skype and it still happens. It could be my internet but while my Skype is open and i am in a call, any games, videos, webpages etc. do not lose internet connection when Skype does. Also, sometimes after disconnecting and reconnecting a few times it will force me to hang up and sometimes I will not be able to rejoin any calls until I logout then log back into skype. Please help. Thanks in advance for any help.

Mac OSX 10.8.5
Internet Connection: 60 Mbps Down/ 5 Mbps Up
Skype Version: 6.15 (355)
Via Wireless Connection:
I am looking at the Skype Preferences:
Advanced Settings:
Incoming connection port: 52743
Could this be the culprit:
Going to search Voice Over I P (VOIP) and incoming port and see if
something comes up.

No Internet access after VPN disconnect

Several of my users have reported that when they disconnect from the VPN, they have no web access without restarting the computer. We're using version 3.8.16. Is this a known issue? Is there a way around this without having to restart the computer? Thanks for any help you can give.

We are having this issse as well has there been any resolution out there? It happens on some and not everytime.

Windows 8 L2TP VPN disconnects at 60 minutes

I have 5 windows 8 machines across various domains all configured with 8-10 L2TP VPN setups to various clients networks. Most of them are to Sonicwall firewalls but a couple are to other firewalls. My Windows 8 machines consists of both upgrades
from Windows 7 and fresh installs. Either way every one of my L2TP connections will disconnect at 60 minute increment, regardless of activity or inactivity, which never happened on Windows 7. I have looked everywhere on the Sonicwalls (all of them
are on the most up to date firmware) and there is no setting for disconnecting after 60 minutes.
The issue must be with Windows 8 - just looking for a registry hack or hotfix that will fix this problem.
Michael E. Wheeler

I also have the same problem but my timeout happens at 49 mins 54 seconds everytime. I recently switched to Windows 8 and I am facing lots of issues with the VPN.
Initially I had installed the VPN version "CISCO VPN 5.0.07.0290-k9" and my VPN would disconnect every 3 to 4 mins. Then later browsed to get the "most compatible" version of VPN "5.0.07.0440-k9" . Now also the same problem perisists. but a small improvement.
Incase I am keeping my access to the Server IP active, working on the sever and not on the local system, then my connection is active for a longer time. If I work on my local system the connection disconnects within a minute.
Since I had to work on my local system also, I did a continuous ping on the Command Prompt and then I can now work on my Server thro VPN and also on my local system for 49 mins. I was searching for a solution when I stumbled on this chain. I am not alone,
but could not find a solution. I hope someone from Microsoft looks at this thread and give a Fix build.
Please post any alternative solution to bypass this issue.

DirectAccess stuck Connecting after VPN disconnect?

We use OpenVPN for our VPN clients coupled with DirectAccess for transparent domain access on Windows 8.1. If I boot a client it connects to DA and everything works as it should. When I connect to OpenVPN on the same client, DA immediately changes to a "Connecting
..." state and stays there, even after I disconnect from the VPN.
If I run a netsh interface httpstunnel show interface it shows a
0x274c failed to connect to the IP-HTTPS server. Waiting to reconnect.
The DirectAccess Client Troubleshooter fails at the IP Connectivity, Infrastructure Tunnel, and User Tunnel Tests.
However, I can access the directaccess server just fine on port 443, even via a web browser.
I've tried restarting the IPHelper service and the IKE service, but DA eventually reverts to the same 0x274c error. The only way to clear it is to reboot the client.
The log from the DA Troubleshooter shows that NLS thinks it's "internal" I believe, as the IsExternal and GetNLS return the internal FQDN of the DA server and try to connect to that, then throw an error 503. Almost everything after that in the
log also fails, of course.
I'm at a loss as to how to solve this.

I found the following KB article, which has helped a little but still hasn't resolved the inability for my client to re-connect after disconnecting from the VPN.
https://technet.microsoft.com/en-us/library/ee809093.aspx?f=255&MSPPError=-2147217396
If I set those two registry entries, a netsh interface httpstunnel show interface
now properly reports that I have "other corporate connectivity available" when I connect to the VPN. A netsh dnsclient show state
also properly detects whether I am inside or outside the corporate network.
However, I still cannot achieve a DirectAccess client re-connection after disconnecting from the VPN. The httpstunnel still reports a 0x274c, failed to connect to the IPHTTPS server. Waiting to reconnect.
I don't see anyting in the Event Viewer on either the client or the server, so I'm not sure where to look next to continue troubleshooting.
Note - the client seems to have full connectivity to the DA server. I can run a Test-NetConnection -Port 443 -ComputerName da.myserver.com and it is successful. I can ping the hostname da.myserver.com and all 4 replies are successful.
I noticed that if I run an ipconfig on the client, the Tunnel adapter iphttpsinterface states "Media disconnected."
Can anyone assist?

Brief vpn disconnections

I have several remote users conneting to an ASA 5510 device. They have Windows 7 (32 bit) machines and connect using Cisco VPN Client (5.0.0.7). Everyone connects fine and is able to work through out the day. They basically use Citrix Reciver to connect to citrix apps and use Cisco IP Communicator softphone for phone service. However, 2 or 3 of them have complained that they get disconnected everyday after being connected for 6 to 6.5 hours. They say it is like clockwork. All their citrix apps lock up and disconnect briefly for 1-3 minutes and then everything comes back online. Normally everything reconnects itself and they do not have to reconnect to VPN client or citrix.
I thought initially it had something to do with Citrix, however one said they were using their softphone when things disconnected. So that points to the VPN client or their internet connection. I rule out their internet connection since it is happeing to multiple people. Has anyone heard of this? It shouldn't be an idle timeout issue since they are actively working all day. Is their something with the client itself timing out or causing brief disruption to the NIC?? Any help would be appreciated. Thanks...
Dave

Hi,
it turned out the problem was due to a mismatch in the ACLs between the ASA and the remote site 2911.
We had no matching line in the ASA config for traffic between the office and the extranet server. On the office router, we had:
permit ip 192.168.1.0 0.0.0.255 host 3.3.3.3
So, on the ASA, we had to add:
access-list office101 line 8 extended permit ip host 3.3.3.3 192.168.1.0 255.255.255.0
I'm not sure why the behaviour was different between the ASA versions i.e. why we did not experience any issues when we had the misconfig at version 8.4(3) but it caused problems with higher versions. Also, cannot explain why it only really seemed to be one site that was affected (we had the same config mismatch at other sites which were seemingly alright)
However, ultimately, it was the config mismatch that was causing the problem and, after rectifying that, we were able to upgrade and our remote site VPN connectivity remained stable.

VPN Disconnect

Cisco VPN Client version 4.8.02.0010 connecting to Cisco ASA5520. I have fireturcks using air cards from ATT. They are configured to automatic VPN Initiation. If I disconnect them from the ASA they will not reconnect until I close the notice on the Client. Is there any way to make the notcies go away or the auto connect to ignore the message? Let me know. Thanks.

I inserted the command banner none
I logged the unit out logged back in then forced a disconnect from the ASA and they still got the notification box. Any other ideas?

VPN Disconnection After iPhone Locks

I'm not sure if anyone else has this issue, but a fix/explanation would be helpful.
Whenever I am on a VPN connection [with 3G as it seems EDGE doesn't want to let me connect another issue entirely] - it disconnects after about a few minutes of being locked. Part of me thinks this has to do with the issues with 3G where it switches unnecessarily.
Hopefully one of you who uses VPN experiences this as well and can help me out!
Thanks kindly,
Chris

Thanks for your post, I have the same problem, but when I asked IT about this, they told me that we authenticate users in a different way.
You wrote: "*The fix was to configure the Cisco firewall VPN user account to allow the client to save the password locally, you must goto the user account and un-check the "inherit" and then the option of "NO" or "YES" can be selected*"
I'm not from IT, but they told me we are using a Cisco ASA 5520 and using user validation by Radius authentication against Active Directory and IAS (Internet authentication Service)
That we don't handle user authentication by Cisco, so there is no way to tell Cisco to allow the users to store the passwords. What Cisco validates is a Group and then passes the rest to the AD.
Any suggestion?

5508 WLC - VPN disconnects from Wlan guest

Strange issue that our support staff is seeing on our guest WLAN.
I have 2 wlans, 1 is production and authenticates our Domain controllers, this is working fine.
The other is a wlan that has restricted access internally, I allow http, https and VPN access out only.
It appears that on the guest wlan, after random amount of time an established VPN connection using Cisco VPN client disconnects.
Wireless connectivity doesnt appear to go down, just the vpn connection.
On this guest wlan, I have configured QOS bronze and I read a link where this may be affecting the UDP conversation between VPN client and end point.
Can anyone shed light on this ?
I just upgraded to latest and greatest code and I am still seeing same issue.
Cheers
Dave

VPN disconnect/timeout

I'm running a 10.5 VPN server with what's supposed to be 24/7 linked 10.4 clients and am getting unexpected disconnects after a couple of days or so. I'm assuming they are timeouts, but on 10.4 there doesn't seem to be any way to configure the timeout interval in Internet Connect. Anyone know how to make a "permanent" VPN connection from 10.4?

vpn-idle-timeout = the amount of time the vpn connection is idle ie. no activity seen on the tunnel, before it is disconnected
vpn-session-timeout = the amount of time the VPN tunnel is allowed to stay up regardless of whether there is activity or not.
This if for specific user-
hostname(config)# username anyuser attributes
hostname(config-username)# vpn-session-timeout
Hope this help.
Thanks
Ajay

VPN Disconnect Issue

I have mac clients running both 10.4.x and 10.5.x. I have a mac osx 10.5.4 server with VPN setup on it. I am using PPTP connection. When a mac connects it automatically disconnects after about 2 minutes. However, Windows clients have no issue maintaining a connection. Is this a known issue with Mac clients or is there a solution to correct this time-out.

The funny thing is WiFi does exactly what we need VPN to do in sleep mode. The second the phone wakes up, WiFi tries to re-establish itself and does so quickly. I REALLY need to have them address this in 2.1 if possible.

VPN Disconnection

Hi
We have a VPN 3000 that we use to connect.
We are recieving reports that some of the users are connected but after a set period of time they are disconnected. Is there any changes that I could look at in the VPN 3000 that could point me in the right direction.
Thanks

Jayesh,
The tunnel should rebuild itself at regular intervals in the background and therefore rekeying and resetting the session but without disconnecting the client.
If your timing is at phase1 then the session should be built and as your connected the phase 2 completion should not get dropped. Do you have a timing limitation on the session as a whole ?
