Unable to access Internet after VPN connection

The Internet cannot be accessed after the VPN connection. The pptp vpn is created to the company through the system network and the sharing center. It can connect to the company network normally, but cannot access the Internet. The specific configuration is the same as that of the XP environment, however, after connecting to the company's network through VPN in the XP environment, the Internet can be accessed normally! The client uses Windows 7 flagship edition.

A: I understand that your client is the flagship version of Windows 7, and you have created a PPTP VPN to your company. You can connect to the company's network normally, but cannot access the Internet. However, XP can normally access the Internet after connecting to the company network through VPN. This problem may be caused by the VPN settings of the Windows 7 client. If you configure to use the VPN connection of the default gateway on the remote network, this problem may occur. This setting overwrites the default gateway setting you specified in your Transmission Control Protocol/Internet Protocol (TCP/IP) settings. I recommend that you follow these steps: the article you see comes from the Active Directory Seo http://gnaw0725.blogbus.com/c1404551/

1. On this Windows 7 flagship server, go to the network and sharing center and click "Change adapter Settings.
2. Right-click the problematic VPN connection and select Properties.
3. Select the network tab. Double-click Internet Protocol Version 4 (TCP/IPv4 ).
4. Click the Advanced button. Clear the check box for using the default gateway on the remote network
5. Click OK and then click OK.

Check whether the problem is resolved. If not, try the following method:

Sometimes, once you deselect the "use the default gateway on a remote network" option, I find this new problem occurs, the Windows 7 client system can only access the computer VPN Server on the Intranet through the VPN connection channel in the future, but cannot remotely access other computers on the Intranet through the VPN connection channel, this is because the Windows 7 client system does not have a route to the internal network of the Organization at this time. To access both the Internet network and any computer on the internal network of the Organization, we need to manually add route records to the internal network of the organization in the client system.

For example, if we want to allow successful VPN connection, the Windows 7 client system can remotely access the 192.168.6.0 network of the Organization (assuming that the internal network uses the gateway address 192.168.6.1, when the network mask address is 255.255.255.0), we first switch the Windows 7 client to the DOS command line status, and then directly execute the "route add 192.168.6.0 mask 255.255.255.0 192.168.6.1 metric 1" command, then, run the route print command in Windows to view the route table of the VPN Client in Windows 7. Then, the client system contains two default routes and one route pointing to the local Internet gateway, another gateway pointing to the internal network of the Organization. In this case, the Windows 7 system can normally access the Internet network and the internal network of the Organization.

1. Collect route tables on win7, WINXP, and VPN servers respectively. In addition, please tell me whether the VPN Server is ISA, RRAS, or hardware VPN Server.
2. A brief introduction to the network topology of the remote network
3. Check whether the LAN Nic of the VPN Server can be pinged.
4. Run tracert 192.168.11.64 on Windows 7. Please inform the result
5. If the problem persists, try to delete and recreate the VPN connection (remember to clear the default gateway check box on the remote network)
