Can't connect to PPTP-VPN server...

When attempting to connect to a DD-WRT PPTP VPN server I kept receiving the general "Can't connect to PPTP-VPN server." message. All of the settings were exactly correct and tested on a Windows laptop. I began writing this because I didn't have any other ideas but half way through it (out of the blue) decided to attempt connecting. It worked!
The only thing I did different was delete the /Library/Preferences/SystemConfiguration contents and reboot.
Let's hope it continues to work. Posting this in case anyone else has the same error as I.

A follow up on the VPN issue: it would only work if my laptop's wireless was tethered off of my Android phone - any other connection would connect to the VPN and get an IP but I couldn't ping anything. Also, after rebooting, I get the exact same damning error message now and any combination of rebooting and removing/renaming (don't ever delete system files!) /Library/Preferences/SystemConfiguration/* hasn't fixed the issue.
I very much hope Apple releases an update soon for this - it's a serious inconvenience! It must be a network stack issue too because I've tried many 3rd party applications that barf as well.

Can't connect to my VPN server from the WAN addres...

I've setup a PPTP VPN server on a Raspberry Pi, so that I can connect to it when out and about and avoid having my android internet use sniffed by random public wi-fi hotspots.
It seems to be working as I setup a Windows 7 connection to it using the LAN address (192.168.1.85) and that connected fine but I can't get it to work through the BT HH3 via the WAN address. I've forwarded port 1723 to 192.168.1.85 and tried disabling the firewall, enabling port clamping and putting the RPi in the DMZ, none of which made any difference.
Is anyone able to help please?

Did some testing from my parents house yesterday and whilst connected to their router (Virgin Media) and/or a local BTWiFi hotspot (I can't honestly remember if I tried both or if I only tested with one or the other), I was able to connect to the VPN Server from my phone.
I can also connect from my home PC using Putty to the VPN Server on SSH (port 22) with that forwarded in the router using the WAN address, so NAT travesal doesn't seem to be an issue.
Yet I still can't connect to the VPN Server from home, whether connected to my HH3 or a local BTWiFI-with-FON hotspot, using the WAN address, only the LAN address, which doesn't make any sense to me.
I don't think it's relevant to this problem but I want to ask a question about the router firewall as the description for Default (which is what I have enabled) says "Allow all outgoing connections and block all unsolicited incoming traffic. Games and application sharing is allowed." but it doesn't appear to block unsolicited incoming traffic as otherwise I don't think I'd have been able to connect to the VPN Server from my parent's house, or on SSH from my PC using the WAN address. So is the description incorrect?

Can't connect to Easy VPN Server using Windows 7 inbuilt VPN client

Hi Everyone,
I would like your help to resolve a vpn issue I am having with my Windows 7 inbuilt vpn client. I am trying to connect to an Easy vpn server on a Cisco 2951 ISR G2. Well, I can connect using Cisco vpn client v5.07 but I can't connect using Windows 7 inbuilt vpn client. Is there any configuration that I am missing so that I can connect using Windows 7 inbuilt vpn client to connect to the vpn server?
Thank you.

Hi MindaugasKa,
Base on your description, your case must is the NPS client can’t pass the NPS policy.
The NPS client can’t connect the network may have many reason, such as the Network Access Protection Agent service not started successful, the certificate not issued properly,
please offer us information when your Windows 7 client denied, such as event id, original error information, screenshot.

Can't connect to a VPN server via Airport Extreme Base Station

My husband is unable to connect to his employer's VPN server through our Airport Extreme when he uses his work PC at home. Strangely, when we had a Dell True Mobile wireless router this was not an issue. He could reach his VPN server via PC, AND our Mac wireless network also worked thru the Dell True Mobile. Is there any way to configure the AEBS to allow VPN connectivity? Do we need to switch to a different brand of wireless router? Please advise.
Mac OS X (10.4.7) Airport admin utilities 4.2

First welcome to the discussions.
To set up the client you'll first have to ask the Network Administrator for the name of the VPN server. The username and other details you will need to log on.
You will also need to find out if the VPN uses PPTP or L2TP over IP Sec. with that information in hand open Internet connect in the Applications folder choose NEW VPN Connection then you click on either PPTP or L2TP whichever the network uses, then click continue in the confiquration pop up menu, Choose Edit confiqurations Then enter the information the Network administrator gave you.
Bear in mind that the OSX client does not work with all VPN's.
You may have to purchase a universal VPN client such as VPN Tracker from Equinux ($90.00).

Can't Connect to Yosemite VPN Server from Mavericks Clients

Hi All,
I upgraded my Mac Mini Server to Yosemite and none of the Mavericks Clients I have (a 13 inch MBA and a 2010 MM) can connect. However all other machines running Yosemite can connect without issue, this includes another 2010 MM and an 11 inch MBA and all iOS 8+ devices. I've tried deleting and recreating the VPN configuration in the local machines. Anyone else seeing anything like this issue? The Mountain Lion to Mavericks upgrade had a similar issue but I believe that racoon was just broken in that release.
Thanks

Hi Linc,
One of them I am upgrading, the other is a machine I am waiting on a different application to update first prior to upgrading. I am guess I am just a bit frustrated, after the Mountain Lion to Mavericks update I had to call in 4 times and talk my way to enterprise support to get anyone that would even try to assist with Server/VPN. It was the 3rd call that they actually acknowledged an issue- guess I was just attempting to verify if others were seeing this prior to calling in. I don't think its unreasonable to think a server upgrade could support clients like with an OS that is a year old. Just want to make sure I am not "seeing things" when looking at racoon logs and seeing very familiar error messages.
Thanks

IVPN starts, but "the pptp-vpn server did not respond. Try reconnecting."

Hi. I am new to VPN, and I just got the software iVPN from Macserve, and the server starts successfully, using either PPTP or L2TP:
But the connections from my network do not connect. Every time I click on "connect" for either network connection, I get the error "the pptp-vpn server did not respond. Try reconnecting."
I set up both connections in my Network Preferences according to the support page (http://macserve.org.uk/support/ivpn/):
My Airport Express configurations have never given me any problems with my home network:
And I think that I forwarded the ports properly (even though my firewall is not activated):
What am I doing wrong?

The Apple routers can be a problem on vpn passthrough.
Ports that are required for vpn are more complicated ..
See earlier post.. eg How do I set up L2TP VPN?
Ports for PPTP which you have opened manually.. are not valid for L2TP.. so you need several more ports opened.
The problematic ones are GRE and ESP which are protocols not ports.
I think you can pretty well assume the apple router running anything that has BTMM in it won't work.. since it will need the port 500 for itself.
On the old express try going back to 7.6.1 firmware.. I have to say I don't use the express.. lots of extreme and TC.. so their firmware issues are slightly different so firmware versions for the express are somewhat different.
Try not to use both port forwards (mapping if you must).. and DMZ.. they can fight each other.. if DMZ doesn't work it is better to turn it right off and forward all the required ports.
Let me recommend a test.
Plug your cable modem directly into the computer running the VPN.. so you have no NAT router in front of it.
Pay attention to the local firewall that apple runs and what ports you will need to open on it to get vpn to work.. this is your best chance to get remote vpn running. If you fail with the public IP on the computer it will certainly fail through NAT.. and generally local firewall will be an issue.
You should of course test that a client in the local lan can connect by the vpn.. it is always worth testing from the easiest configuration to the most complex.
So local lan just as you have now..
Then direct cable connection to the computer.
Then NAT router.. but you can pretty well assume apple routers are going to be problematic because apple want to dally at BTMM using same ports as IPSEC uses for L2TP.
My email is live.. roll your mouse over it and talk to me direct..

Cannot connect to PPTP VPN

am working on setting up a VPN on my MS Directaccess server. technically the vpn is up and running and working already. it is using a certificate that is issues to the DA server by the DA server. My domain joined PC's connect fine. I can also connect a non domain joined machine if I import that certificate into the PC. However I cannot connect any OSX clients or my android phone. We have opened up port 1723 on the firewall. I have tried to connect from my home and from another businesss locally to make sure it wasnt just my home router causing the issue for some reason.
I get this in the osx console log (I replaced the external IP with 1.1.1.1 for posting this online)
3/19/14 7:55:21 AM pppd[6282] pppd 2.4.2 (Apple version 412.5.70) started by admin, uid 501

On the directaccess server I get this in the event viewer everytime the OSX client tries to connect. This at least proves that I can at least connect to the server from the outside.
Event 20209, RasMan
A connection between the VPN server and the VPN client 24.97.100.42 has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47).
Im assuming this isnt a port or protocol issus since I can connect via my non domain joined Windows PC. Im out of ideas as to what I can do next

Here is a snapshot of my console

Can't connect to work VPN

Hi,
I've read through some previous posts, but haven't had luck connecting to the corporate VPN at work. I can sucessfully connect using a mobile wireless dongle (that uses the mobile telephony network) connected to my computer. I tested this to make sure everything works. Unfortaunately i cannot conect to work VPN server via my wireless LAN at home.
I'm using WRT54G2 linksys wireless router and have turned on the VPN options.
I can ping the VPN server, but I can't connect. I think it fails to authenicate, keeps trying, and I just have to cancel it after a few minutes.
Any ideas? Is it the router or could it be my service provider (iinet) that block the VPN connection somehow?
Thanks
Tim
Solved!
Go to Solution.

I tried connecting (with an ethernet cable) directly to the modem and I have the same problem.
I can still ping the VPN server at work, and I can access the internet fine except the VPN connection. It fails to connect to the VPN server and eventually times out. I get an error "VPN server failed to respond". I'm using Nortel VPN Client to connect (everything was installed and configured by my work IT).
I've asked by ISP (iinet) to open port 500udp (which is what my work IT guys suggested). I haven't heard back from my ISP yet.
I'll let you know if it works after I hear back from my ISP. Fingers crossed...

OSX 10.8 server Set VPN server in Local net, How to restrict the Local some IP connect to the VPN server?(noob,so need clearly)

the tittle is my question. I am noob , so I hope i can make my question clear. Now i 'd like to tell you more about my question:
My aim is to set a VPN server in Local lan, then ppl can connect to the VPN server, But I dont wanna all of the Local lan IP cant connet to it. So I neet to set a rule to restrick some local Ip to connect failure, just like banning so IP in a rule.such as: just like the "192.168.4.3~192.168.4.20 ; 192.168.7.3~192.168.7.20 " IPs can connect . the IPs which outside the rules can not do.
my step is following:
1) install server app
2)and then i set a VPN server , finally the VPN server can be connected successfully by local lan computer(PC or Mac)
3)But i found no restrict IP founction in Server app panel.
4)then i down load workgroup manager, and found nothing there about such a founction about IP restriction.
so can you tell me how to aproach my aim?
Please tell me in a clear detail,I am noob
thank you

Won't the password restrict everyone from connecting unless they know the password?
I have never worked with a VPN server, so I can't really add any suggestions. Below are links to Apple support articles, but I'm not sure they will help you:

VPN - Advanced Setup
VPN - Connect

Can't connect to L2TP VPN

Whenever I try to connect to a VPN server using L2TP/IPSec I get the message: "The L2TP-VPN server did not respond". I could connect to that server using Snow Leopard and I can connect to it using Windows 7 (which is also installed on my mac).
By the way, when I force Windows 7 to use CHAP authentication instead of PAP I get a similar message. Too bad I can't force Mac OS X to use PAP.

Hello,
Dont know if you need help with this still. But here is an article on how to use PAP on Mac OSX:

Now what I want is the possibility to use PAP on Iphone and IPAD... :/

You will need a library to handle SSH connections.
I'm using SSH.NET, you can find info on it here : http://www.powershelladmin.com/wiki/SSH_from_PowerShell_using_the_SSH.NET_library
It has a bit of a learning curve but the web site has some fairly good tutorials.

I don't even know if following the mantis directions has resulted in the creation of a database or not. Where would it be?
Thanks for any help.
Intel iMac Mac OS X (10.4.10)

I've just done a clean install of OSX Server and added the latest MYSQL packaged installer. Afterwards I found the lock file in /private/tmp/mysql.lock
The easiest way to solve this problem is to create a symbolic link so that the lock file appears to be in right place.
e.g.
cd /var
sudo mkdir mysql <== this assumes the directory is missing
cd mysql
sudo ln -s /private/tmp/mysql.sock mysql.sock
After this msql commands should work fine, and you've not fiddled with the security settings on users/groups.

I have trying for days to download Firefox 4.1. It goes through all the motions, but when it gets to the final step, it can't connect with the download server. What should I do? It keeps telling me this download is strongly recommended.

It downloads everything, but when I re-start, it can not connect to the download server.
I've left it open and it never connects.
