Cannot sustain VPN connection

I need to work from home 2-3 days a week and moved to Infinity just before Xmas - now I can't sustain a VPN connection, over either wireless or wired ethernet connection.
The connection is made fine, first time, but drops after usually a minute or 2, and after that will not reconnect without a PC reboot (and sometimes not even then.) From the VPN client (Cisco) error messages the client is unable to resolve any of the four VPN gateways that are available.
If I use a mobile dongle to connect the PC to the internet, the VPN stays up - but is too slow to be workable (and expensive) - but that to me rules out any client/PC issues.
I've been through this forum quite extensively and this looks like the problem with "BT Web Address Help" that many others have had - but I can confirm that I have opted-out of this service at least a week ago now, and there's no change in the way VPN behaves.
Please can someone assist on this as I'm unable to do my job without home VPN access - this is making me do an extra two 80 mile round trips each week to connect to the corporate network.

Changing the PC's MTU value might help, or even changing your DSL Router?

The Homehub2 often doesn't like transferring large files especially if fragmented, which is more likely when using VPN.

Aiport Extreme cannot establish VPN connection through router must bypass

Hello - I own an Airport Extreme with the latest firmware update. I cannot connect to my work VPN through the Airport Extreme router. If I bypass the router and connect directly to my modem the VPN works fine. My VPN connections also work fine in any other internet hotspot. Any ideas Apple folks? I am using MacPro, and MacBook with bootcamp MacOSX and Windows XP Pro.

My workaround was taking the router back and getting a D-Link router. Had it set up in 10 minutes with the VPN working, and staying connected. I agree, there is something with the firmware on the router. Good luck!

Cannot establish VPN connection

I am using wicd to manage my network connections.
I am now trying to establish a VPN connection via pptpsetup, but it turned out that it failed to get a sucessful connection. The following is some debuging information:
PS:
I can use the VPN on my Android phone and Windows 8 computer with their default settings.
The router used is TP-LINK WR841N. I also tried to make the VPN connection throgh a Windows XP guest in my Virtualbox, but I get a 619 ERROR.

Hi,
I don't want to sound sarcastic but why didn't you try moving to the NetworkManager utility, I remember well that (yeah it's a Shitian) back in Backtrack 5 and even the fourth connexions were managed by wicd and always caused troubles at some point. NetworkManager handles very well VPN connections without problems and still allows you to make advances configurations. Maybe you should consider trying it in your Virtual Box and post results. Sometimes thiking easy avoids headaches and lets you relax.
On the other hand, it is true that router's "PPTP & VPN passthrough" option can cause troubles when using VPNs, and catalin's solution might be the best, but unless you absolutely need to use wicd (I can't think of a reason right now), you should consider easing things up with NetworkManager. Again just my belief.
Are you trying to connect a VPN or create a VPN connection betweed two points ?
Hope this helps.

I cannot establish VPN connection with rv120w to shrew soft client

1. I bought 2 rv120w router and install one direct to WAN and one behind router-hub.
2. one behind router is set DMZ, and each are conneted Site to Site vpn
3. I need to connect each site with my mobile devices(1 notebook, 2 Win8 tablets, 2 android devices )
4. i use wibro mobile router, win8 devices're behind router, and their fort is fowarded(DMZ)
5. I'll take care of Android devices later, here now, my trouble is Win8 devices
6. i installed cisco QuickVPN software. frankly,that software is shit. i don't know why but it even cannot reach router, no log generated on rv120w. and i dont want PPTP connection. sorry for criticism but I'm sure many of QuickVPN users(and people who fail to be a user) agree with me. it's 2014. not 1998.
Cisco should be shamed for that software. it looks like a second grade collage student's 2nd semester project(Many of them're batter nowadays.) and doesn't work.
more amazing fact is that's only software that RV series provides officialy. What the...so in conclusion, Cisco does not provide any IPSec client connection tool at all. does that makes any sense?
7. i tried 10 or more hours to make IPSec client connection with many vpn client soft ware, this is my closest shot.

Hi kastwf001,
My name is Mehdi from Cisco Technical Support, just want to inform you regarding QuickVPN is an light software using IPsec service of windows, so here it depend of windows and firewall ... IPsec setting on windows, encryption ...
anyhow for RV120W it's open for 3rd party software as ShrewVPN , TheGreenBow ... and working as expected since those software are using their ip sec services ..
Please follow configuration steps on RV120W and ShrewVPN (screenshots taken from you post) :
Please let me know if you have any question
Please rate the post or mark as answered to help other Cisco Customers

Cannot get VPN connection working

I set up my company laptop (running Ubuntu Linux) to connect to the company VPN in about 2 minutes, but using the same settings in "Internet Connect" on my iMac G5, it times out, telling me it cannot get a response from the server.
I notice also that in the Ubuntu setup, the group name and IP address are mandatory and over-riding the group name with your own user name is optional. In the OS X VPN setup, the reverse is true - the "account" (which presumably refers the user name) is mandatory and the group name is optional.
So, I'm using the same IP, the same user and group names & passwords. So why does it connect first time on Ubuntu, but time out on the Mac (on the same network)?
I also tried importing the configuration settings from the Ubuntu VPN Client, but got a "file is invalid" error.

Solved the problem. I needed the Cisco VPN client software, which I got from the Sys Admin at the the data centre that hosts my VPN.
Not sure what the built-in OS X VPN settings are supposed to support, but they obviously don't support Cisco!

"Back to My Mac is turned on, your VPN connection cannot be established"?

Hi,
I searched for this recurring notice that I am getting " Because Back to My Mac is turned on, your VPN connection cannot be established", and came up with this thread: http://discussions.info.apple.com/message.jspa?messageID=8436720
However, I am not trying to establish a VPN when I get this message (and don't have one AFAIK).
Any idea what might be causing this message? I can't seem to figure out what triggers it, it just seems to pop up every hour or so. iChat is the only thing I have been using recently that seems to
Is there any way to discover what VPNs my laptop has set up? I don't have any additional software that is specific to VPNs, so it would have to be something already built into the OS. Does the Transmission application create a VPN? That is the only thing I can think of.
Any other ideas on what might be causing this message?
Your help is appreciated!
A.

If you have a VPN installed (by mistake?) you should be able to go to your System Prefs > Network and see the VPN listed in the left hand column along with Aiport and Ethernet. You can un-install by using the minus button at the bottom of the column.
The link provided shows you how to install a VPN client with screen shots, including one of this Network Prefs screen and what a VPN client looks like.

AnyConnect 3.1.01065 error - Failed to install AnyConnect VPN Profile because of file move error. A VPN connection cannot be established.

I've got a user running:
AnyConnect 3.1.01065
on
Windows 7 64bit.
Several weeks ago she started encountering the following error:
-after logging into Windows and launching the AnyConnect client, she enters her username and password and successfully authenticates.
-the connection is not established and she's presented with the following message: "Failed to install AnyConnect VPN Profile because of file move error. A VPN connection cannot be established."
After doing some troubleshooting, inlcuding uninstalling/reinstalling the anyconnect client, it seems the culprit is the following file:
C:\ProgramData\Cisco\Cisco AnyConnect Secure Mobility Client\Profile\<filename>.xml. When the problem occurs (which is not regularly, sometimes it occurs daily, sometimes just once a week) examining that file indicates it has no security or permissions set. Quitting the AnyConnect software, modifying the file so that the user has full control of it, then relaunching AnyConnect fixes the problem (until it happens again). Uninstalling, and making sure to move C:\ProgramData\Cisco to the trash, then reinstalling did not seem to help.
The closest match in these forums is the following thread, https://supportforums.cisco.com/message/3760446 - though no clear resolution was given.
Has anyone else encountered this, and been able to fix it?
Thanks much.

Just FYI, it seems at least in this case, purging all the previous system restore points seems to have resolved this issue...

Cannot establish a VPN connection in Lion

I have followed the instructions in this support article but cannot create a VPN connection:
http://docs.info.apple.com/article.html?path=Mac/10.6/en/9010.html
I've tried the steps outlined in this article, and successfully completed everything but still cannot create a VPN connection:
http://anders.com/guides/native-cisco-vpn-on-mac-os-x/
I have all the correct credentials for my VPN network (vpn address, group name, shared secret). I always receive a server time out error.
I am able to successfully connect to my work VPN using the Cisco VPNClient. But unfortunately it only runs in 32-bit mode. I prefer to boot in 64-bit mode and would prefer not to reboot everytime I want to establish a VPN connection.
I have been working on this issues for three days straight and am getting nowhere. My work is an unsupported IT environment, and the IT support subscription service we use will not handle any Mac issues.

Hmm, no changes. Still the same issue. I deleted the files described, rebooted and reconfigured the network.
hmm, Finder still remembers his old server connection settings, maybe i should delete those, too. Any idea where finder stores his server connections?
In my perception the message that no secure connection can be established comes up immediately after sending the connect command. I don't think that there is network traffic, there is no noticeable latency...

Hi Dude,
My firewall is disable in my db host.
I also check the firewall on client end and it is also disabled.
I also talk to my Network Administrator for adjustment in Router and Firewall to allow port 1521 to accept connection but still unsuccessful.
What seems to be the problem ?

Cannot ping pc behind router in vpn connection

I have set up a vpn tunnel using two wrv200 vpn routers. The lan and wan connection works fine and the tunnel is connected successful between two locations. I can ping the remote wrv200 router from the opposite side. However, I cannot ping remote pcs connected to the router from other side. I can ping the pcs from the router on the same side. Does anyone experience the same problem? Any suggestion or solution to it? Please help!

windows firewall is disabled on the pcs. I can ping the pcs on the side from the router. If I can ping remote pc from the tunnel, then I shouldn't have any problem with the vpn connection. When I ping remote pc from opposite side through the tunnel, the Request time out message displays. The same to the tracert command.

Firefox cannot load websites when connect/disconnect from any VPN connection

I am consistently uses OpenVPN and RamsesVPN connectivity. But whenever i switch between the VPN connectivity or connect into any VPN or disconnects existing VPN connectivity. My Firefox Browser is unable to load new webpages/Refresh existing open TABS.
In order to restore, i have to restart my Browser each time, whereas i am not facing this problem with Chrome.
I am running with Windows 7 Enterprise edition, and latest Firefox version.
Is there any method to avoid these restarts ?

Hi, this bug is old, but it has useful info for VPNs
See for reference Bug 702111
And there are built in features on the about:config file that you can tweak the number of connections and allowing pipe lining: [http://support.vpnsecure.me/articles/ssh-tunnelling-proxy-troubleshooting/tweaking-firefox-for-best-performance-security Third party information on these connections]
Other suggestions I have seen are to add bookmarks while logged into either vpn. (For example, bookmark the frequent sites you use in either vpn in separate folders)
In Firebug, when you connect or refresh the page when moving from one VPN to the other, do you see a termination in the connection to the first vpn?

Cannot logon via VPN connection using an ICS server

At home I have a small network set up, using a central PC A on which Internet Connection Sharing (ICS) is enabled (IP address 192.168.0.1 is allocated to this PC). PC B, having VPN client V4.0.x loaded, is connected to PC A. ICS dynamically attributes an IP address 192.168.0.n to PC B. Although a VPN connection (via IP address 194.79.185.227) can be created with a server at the office over the internet, it is impossible to perform a Windows logon and map for example a drive. When using a direct internet link via a telephone modem, it is possible to logon on the office server via the VPN connection.
I have the impression the Cisco firewall inhibits the logon, because of a IP address conflict. When looking into the "Status/Statistics/Route details" window of the VPN client, I notice the secured route 173.19.31.0 is available during the VPN connection. Using the direct telephone line it is possible to ping this address. On the same PC this is impossible, when the ICS server (PC A) is used for the internet communication. The server I am trying to reach at the office has IP address 173.19.31.1.
On the Cisco web site, I found out, that such a configuration should work. Which settings are important with this respect?

I have never found a version of ICS that works with VPN.

VPN Connection assistant (VPNUK via OpenVPN) cannot change network connection

I have an issue with using my VPN assistant via VPNUK.net.
The connection assistant will update the VPN connection with a new server IP and connection configuration based on what you select in the application.
There is no error specifically about the settings, but when trying to establish a connection im told that the connection failed. I then manually check the VPN in network connections and the new settings are not applied.
I suspect that the application does not have access to change the network settings, even if i run as administrator.
Are there any other privileges i need to set? Only a problem in windows 10.
Cheers
Mark

Hi Mark,
My name is Adam and I am with the Windows Beta Networking support team. I would recommend running procmon (click
here
for download link) when reproducing the behavior. You can then filter on the VPNUK process and scan for any status results such as Access Denied.
Do you get any error messages or warnings logged in event viewer at all?
Have you also engaged with VPNUK to see if they have seen issues with their client when installed on Windows 10 Preview?

Cannot establish a working VPN connection...period

I am going nuts. I have been trying to get a vpn connection established for two weeks. I am using a Linksys BEFVP41 router and have tried to connect with Snow Leopard's built-in Cisco ipsec vpn, IPSecuritas, and VPN Tracker. No luck. I'm willing to replace the router with anything that will work. My office network consists of a vpn router, a droboshare that I want to be able to access remotely, and three office macs - two of the macs are MacBook Pros on which I want to be able to set up vpn connections. Any suggestion on a router, vpn client, configuration settings files, etc. would be greatly appreciated.

This may help: Mac OS X 10.5 VPN.

Window 8.1 system unable to access network shares via VPN connection

Is there something inherent to Windows 8.1 that prevents it from accessing shares on a domain?
I know that it cannot join a domain, but does that also mean that it cannot access shares which are on a domain?
My problem is that I have several user that are running windows 8.1 that are connecting to our network via a VPN.
The users have domain accounts but their computers as windows 8.1 cannot joined to the domain.
So to access network shares they have to use their domain credentials to create a VPN connection.
Once connected the user can RDP to systems on the domain using their domain accounts, so I know that their user names/passwords and permissions are correct. They can access these systems using the computer name, so I don't feel that I have a DNS issue.
They can see the shares on our file server, but when they try to access their departments shared file, they receive an access denied message. There are a few shares that are completely wide open, shared to all users and all departments but they cannot access
those shares either.
You can ping the file server, from the the client when they are connected to the VPN but you just cannot access any of the shares.
So...
I am thinking that it has something to do with windows 8.1 and not being able to join a domain, but I cannot find anything to explicitly support this thought.
Other users running a variety different OS (windows 7, OSX, Linux) can all access the shares without any problems via the VPN, so I am a little stumped.

I have done some more testing and oddly enough I can map a drive if I use the IPaddress, but not the computer name, when checking the check box "connect using different credentials"and providing they users domain credentials.
This seems to point to a DNS issue, one would think, but I can hit the file share server by name \\fileserver.dev.lan
I can see all the shares, so dns seems to be fine right?
So I don't understand why I can map a drive using do the IPaddress and not the machine name, but yet I can see and ping the server by name?
When I try to create a mapped drive by machine name I receive the following message:
Windows cannot access \\fileserver.dev.lan\all
You do not have permissions to access \\fileserver.dev.lan. contact your network administrator to request access.
But if I use the \\x.x.x.x\all using the very same user and password I get connected with no problem.
This only seems to happen on windows 8.1, which leads me to think that has something to do with OS.
I am thinking about upgrading to windows 8.1 pro, but I don't want to go though the hassle and expanse is the OS is not the problem.
