LAN DIsconnected After PPTP VPN Conected

Possibly the VPN is configured for no split tunneling, which will (more or less correctly) ensure all connectivity is routed through it ...

Hi Garry,

From other Service provider , we are able connect VPN and able access LAN Resources.
Is it a Network COnflict issue

Hi Ramu,

Assuming your local network is 192.168.1.x and the remote network is 192.168.1.x, when you connect your PPTP VPN, which by default uses the remote gateway. This is most likely why you're not able to access local resources.

Solution would be to change your local network or the remote network, if possible. Otherwise you will experience this problem going forward. You could turn off "use default gateway remote gateway" and this may allow you to access local resources, however it's not an ideal solution as half your traffic will be trying to route internally and the remainder across the VPN. Please see the following link for turning that feature off: http://www.solo-technology.com/blog/2009/08/14/windows-vpn-tweak-dont-use-remotes-gateway/

Hope this helps.

Hi,
here my exact info i am providing with attahcments to avoid confusion .
My System TCP/IP details are :
Ip address before conneting to VPN -
                                            IP address          : 172.18.140.126 /24
                                            Default-Gateway : 172.18.140.1

Ip address after conneting to VPN -   10.11.17.202
                                   Subnetmask  -255.255.255.255

Problem :
After Connected VPN ,from my PC  i am unable to comunicate to 172.18.140.X Network,where as we things are fine from other Network after connecte dto the same ,they are able access their LAN resources but we are not able to do that.

Here attached the Route Print details before and After VPN connection

pls suggest ,what could be the issue , i dont beleave the issue is due to split tunnel as we are getiing things smoother frm other Network.

Are you using the windows built in PPTP client or a 3rd party?

Can you check the split tunnel option, as this can be a possibility and should not be ruled out based on your judgement. You never know until you try and it only takes less than a minute to change and reverse back to default.

Hi,

It is built in PPTP Client in Windows 7 OS. PPTP VPN server is not in my hands to check the Split tunnel feature,can i check in the PPTP client, if so how to do that . Will you pls with a Steps
