Each Web-based VPN connection typically uses two various IP addresses for the VPN customer computer system. This is the IP address that's utilized to establish the preliminary TCP/IP connection to the VPN server over the Web.

This IP address generally has the very same subnet as the local network and thus enables the client to interact with the regional network. When you set up the VPN server, you must configure a DHCP server to assign addresses to customers, or you can create a bank of IP addresses to appoint to customers directly from the VPN server.

If this choice is chosen and the reliable remote gain access to policy is set to permit remote access, the user will be able to connect to the VPN. I have actually been not able to re-create the circumstance personally, I have actually heard reports that a bug exists in older Windows servers that can cause the connection to be accepted even if the effective remote gain access to policy is set to reject a user's connection.

Another common VPN problem is that a connection is successfully established however the remote user is unable to access the network beyond the VPN server. By far, the most typical cause of this problem is that consent hasn't been given for the user to access the whole network. To allow a user to access the whole network, go to the Routing and Remote Access console and right-click on the VPN server that's having the problem.

At the top of the IP tab is an Enable IP Routing check box. If this check box is allowed, VPN users will be able to access the rest of the network, presuming network firewall programs and security-as-a-service settings allow. If the checkbox is not chosen, these users will be able to gain access to just the VPN server, however nothing beyond.

If a user is dialing directly into the VPN server, it's usually best to configure a fixed route in between the client and the server. You can set up a fixed route by going to the Dial In tab of the user's properties sheet in Active Directory Users and Computers and selecting the Apply A Static Path check box.

Click the Include Path button and then get in the location IP address and network mask in the area offered. The metric should be left at 1.

Other concerns can contribute to this issue, too. Make sure the resources the user is attempting to access are in fact on the network to which the user is linking.

A VPN connection to the other subnet might, in reality, be needed. A firewall or security as a service option could also be to blame, so do not forget to examine those services' settings, if such elements exist between the VPN server and the resources the user seeks to reach.

The very first possibility is that one or more of the routers involved is performing IP packet filtering. I suggest examining the customer, the server and any makers in between for IP package filters.
