Now that I've discussed reasons why a connection might be refused, let's take a look at the opposite problem in which unauthorized connections are accepted.

This problem is much less common than not getting connected at all, but is much more serious because of the potential security issues. If you look at a user's properties sheet in the Active Directory Users And Computers console, you'll notice that the Dial In tab contains an option to control access through the remote access policy. If this option is selected and the effective remote access policy is set to allow remote access, the user will be able to attach to the VPN.

Although I have been unable to re-create the situation personally, I have heard rumors that a bug exists in Windows that causes the connection to be accepted even if the effective remote access policy is set to deny a user's connection, and that it's best to allow or deny connections directly through the Active Directory Users And Computers console. Another common VPN problem is that a connection is successfully established, but that the remote user is unable to access the network lying beyond the VPN server.

By far, the most common cause of this problem is that permission hasn't been granted for the user to access the entire network. If you have ever worked with Windows NT 4. This particular setting doesn't exist in Windows , but there is another setting that does the same thing.

To allow a user to access the entire network, go to the Routing And Remote Access console and right-click on the VPN server that's having the problem. Select the Properties command from the resulting shortcut menu to display the server's properties sheet, and then select the properties sheet's IP tab.

If the check box is not selected, these users will be able to access only the VPN server, but nothing beyond. The problem could also be related to other routing issues. For example, if a user is dialing directly in to the VPN server, it's usually best to configure a static route between the client and the server.

This will cause Windows to display the Static Routes dialog box. Click the Add Route button and then enter the destination IP address and network mask in the space provided. The metric should be left at 1. If you're using a DHCP server to assign IP addresses to clients, there are a couple of other problems that could cause users not to be able to go beyond the VPN server.

One such problem is that of duplicate IP addresses. If the DHCP server assigns the user an IP address that is already in use elsewhere on the network, Windows will detect the conflict and prevent the user from accessing the rest of the network. Another common problem is the user not receiving an address at all. However, there are situations in which an address assignment fails, so Windows automatically assigns the user an address from the If the client is assigned an address in this range, but this address range isn't present in the system's routing tables, the user will be unable to navigate the network beyond the VPN server.

If everything seems to be working well, but you can't seem to establish a tunnel between the client and the server, there are two main possibilities of what could be causing the problem.

The first possibility is that one or more of the routers involved is performing IP packet filtering. IP packet filtering could prevent IP tunnel traffic. I could not find a solution at the Cisco site nor via googling.

What do the logs say? Click right on the Anyconnect icon and choose logs. Did you tried to uninstall and reinstall the client yet? Thanks a lot for the quick reply,Uninsatall and installed 2 times, but found not solved, wait a minute, i will copy and paste the logs, ie. Dear Maxim, i pasted the log in paste bin, pastebin. It's not the correct log.

Try to find the "message history". We have to find out what happens when your client is trying to create the vpn tunnel.
