VPN connects but cannot connect to LAN nor access Mapped Drives.

Hello Cisco Community,


My name is Carlos Almeida. I'm running into a problem with one of my clients' Cisco VPN Client. VPN has been set up properly, but when he connects to it. It says it is connected, but he is not able to access any of the network folders, or if he opens IE it says "IE Cannot display the webpage".


What I found even stranger was the fact that it does not matter where he is, for example if he is at home, or working from another state, it does the same thing.

One more weird fact is once he connects to the VPN and I am remotely connected to his machine, I no longer am able to log into his machine remotely if he is connected to the VPN.


I've already enabled the option to "enable LAN" within the VPN Client, but the same still happens.


I've had this ticket opened for about 9 days now, and I just have no idea what is happening.

Any help would be really appreciated.


Thanks,


Carlos Almeida Jr.

Have you tried changing the transport protocol in the client from TCP to UDP?  It's a radio button on one of the tabs in the connection entry.

Thank you for your quick response.


I actually did try that option, but with IPsec over UDP when I tried to connect the VPN I got an error message stating"Secure VPN Connection terminated locally by client. Reason 414: failed  to stablish a TCP connection." And VPN would not connect.


Thanks again for your response.

It sounds a lot like  either a crypto map ACL issue or a NAT exemption config issue.  Can you post them here?

I am sorry if I did not explain the situation clearly enough.

What I want to do is basically what everybody who has a VPN set up wants. Once the VPN is connected, I would like for my customer to be able to surf the internet, and simply be able to see and connect to his network folders (mapped drives).


What is going on right now is. The VPN connects properly, but as soon as it connects, he loses access to the internet. And, while the VPN is connected he cannot view or access his network folders that are on the server that he is connected to via VPN.


Thank you for your help !!

Please post your configuration ( remove public ip's ). It appears like you need :-

1> Split Tunnel for internet access for the client i.e. The vpn client will only tunnel the traffic that is internal to your site and rest everything will go to his isp gateway.

2> For internal resources it appears that you need no nat statements and reverse route set up.


Thanks

Manish

Just to add a little note to this thread. The problems is not happening for everybody. Only this specifc user is having the problem. I have set up other VPN for different users from the same company with the same settings and everything works properly.


Thank you all for your help !!
