What to do when Win7 connection VPN cannot access intranet

Workaround:

A problem that is easy to connect to VPN under the corporate Unit network, because the VPN connection is global and can change native IP, resulting in the inability to access the internal network of the company. To solve this problem is not difficult, with the help of the modified routing table to bypass, so that access to the internal network or through the local gateway, the following describes the operation methods, such as Windows system for example.

Open the Notepad program and add the following to save as a Bypass.bat file. Modify the code appropriately and change the following 192.168.1.0 to your own gateway. Note that the last must be 0, such as your gateway is 192.168.1.1, then write 192.168.1.0 (gateway information can be seen in the network connection state, you can also use cmd ipconfig command query).

@echo off

for/f "Tokens=3"%%* in (' route print ^| findstr ' <0.0.0.0> ') do set "gw=%%*"

Ipconfig/flushdns

Route add 192.168.1.0 Mask 255.255.255.0%gw% Metric 25

Run this batch file before connecting to VPN to set up the routing table to use. If you need to delete a routing table modification, save the following as a revocation.bat file and run it (the following gateway IP replaces the one you set before).

@echo off

Route Delete 192.168.1.0

One, 720 error "cannot establish a connection to a remote computer. You may need to change the network settings for this connection "workaround

This error tip is the most common, possibly setting & use environment issues, or VPN line problems. Try connecting several times or using a different environment, such as connecting a friend to the same line. If all is the same mistake, probably is the VPN line problem, the specific contact VPN service provider solves. If you suspect a local problem, try the following methods:

1, restart the computer and network, reset a VPN connection, you need to ensure that the setup process is correct.

2, check the router and so on have no close PPTP/L2TP protocol support, check the method view here.

3, using Winsockfix and other network repair software to try to repair the network.

4, unloading load to install the network card driver, can be used to drive life and other software.

5, reset TCP/IP protocol, the method can be seen Microsoft official help document.

6, replace other VPN protocol connection use, for example OpenVPN connection way.

Two, 720 error "PPP Control Protocol Not configured" workaround

When you try to connect to a remote Access Service (RAS) server by using the TCP/IP protocol, you may receive the following error message: "The PPP Control protocol is not configured" and this problem occurs if your computer and the RAS server do not have a shared protocol or a RAS configuration is incorrect. The workaround is as follows:

1. Find out what protocol the RAS server is running and make sure that the RAS service is properly installed and configured (or ask your system administrator to do this).

2. After you figure out what protocol the RAS server is running, make sure that your windows-based computer is running the same protocol as the one that is running on the RAS server:

A, the control Panel to open the "Network connection" option (WIN7/8 system is "Network and Sharing Center"-"Change adapter Settings")

B, the right mouse click VPN connection, and then click Properties.

C, in the VPN Connection Properties dialog box, click the Network tab to ensure that you have a protocol running on the RAS server.

3. If you do not have a protocol running on the RAS server, add the required protocols:

A, click Install, click Protocol, and then click Add.

B, click the protocol that you want to install, and then click OK.

C, in the VPN Connection Properties dialog box, click Close.

The above is Win7 connected VPN can not access the intranet solution, in fact, the solution is still very easy to grasp, I hope to help.
