For the connection to be established, the settings of the connection attempt must:. For more information about an introduction to remote access policies, and how to accept a connection attempt, see the Windows Server Help and Support Center. Cause : The settings of the remote access policy profile are in conflict with properties of the VPN server.
The properties of the remote access policy profile and the properties of the VPN server both contain settings for:. If the settings of the profile of the matching remote access policy are in conflict with the settings of the VPN server, the connection attempt is rejected. Solution : Verify that the settings of the remote access policy profile aren't in conflict with properties of the VPN server.
Cause : The answering router can't validate the credentials of the calling router user name, password, and domain name. Solution : Verify that the credentials of the VPN client user name, password, and domain name are correct and can be validated by the VPN server.
Solution : If the VPN server is configured with a static IP address pool, verify that there are enough addresses in the pool. If all of the addresses in the static pool have been allocated to connected VPN clients, the VPN server can't allocate an IP address, and the connection attempt is rejected.
If all of the addresses in the static pool have been allocated, modify the pool. Solution : Verify the configuration of the authentication provider. Solution : For a VPN server that is a member server in a mixed-mode or native-mode Windows Server domain that is configured for Windows Server authentication, verify that:.
If not, create the group and set the group type to Security and the group scope to Domain local. You can use the netsh ras show registeredserver command to view the current registration. You can use the netsh ras add registeredserver command to register the server in a specified domain. To immediately effect this change, restart the VPN server computer. For more information about how to add a group, how to verify permissions for the RAS and IAS security group, and about netsh commands for remote access, see the Windows Server Help and Support Center.
If not, type the following command at a command prompt on a domain controller computer, and then restart the domain controller computer:.

Cause : The appropriate demand-dial interface hasn't been added to the protocol being routed. Solution : Add the appropriate demand-dial interface to the protocol being routed.
For more information about how to add a routing interface, see the Windows Server Help and Support Center. Cause : There are no routes on both sides of the router-to-router VPN connection that support the two-way exchange of traffic.
Create routes on both sides of the router-to-router VPN connection so that traffic can be routed to and from the other side of the router-to-router VPN connection. You can manually add static routes to the routing table, or you can add static routes through routing protocols. For more information about how to add an IP routing protocol, how to add a static route, and how to perform auto-static updates, see Windows Server online Help.
Cause : A two-way initiated, the answering router as a remote access connection is interpreting router-to-router VPN connection. Solution : If the user name in the credentials of the calling router appears under Dial-In Clients in Routing and Remote Access, the answering router may interpret the calling router as a remote access client. Verify that the user name in the credentials of the calling router matches the name of a demand-dial interface on the answering router.
If the incoming caller is a router, the port on which the call was received shows a status of Active and the corresponding demand-dial interface is in a Connected state.
For more information about how to check the status of the port on the answering router, and how to check the status of the demand-dial interface, see Windows Server online Help. Cause : Packet filters on the demand-dial interfaces of the calling router and answering router are preventing the flow of traffic. Solution : Verify that there are no packet filters on the demand-dial interfaces of the calling router and answering router that prevent the sending or receiving of traffic.
For more information about how to manage packet filters, see Windows Server online Help. Cause : Packet filters on the remote access policy profile are preventing the flow of IP traffic. Skip to main content. This browser is no longer supported.

However, if we use this method, we need to open port on our router to allow VPN connections through the router. For instructions about how to open the port, please see the documentation from the router manufacturer. More information:. Virtual Private Networks. Hope this helps. This worries me.
This is asking for trouble. So is adding remote access which effectively makes the DC multihomed as soon as a client connects. Giving a DC more than one IP may cause all sorts of odd problems with name resolution and computer browsing. If you're on a smaller network, or only need to access resources on the local subnet, disable this gateway feature.
On the Advanced settings window, uncheck the box "Use default gateway on remote network". Short version: If you need to access resources on multiple networks at your company, use the remote gateway.
If not, don't use the remote gateway. The Advanced tab does not have any options that would be useful for a typical connection. You can configure the Windows firewall and Internet Connection Sharing from this tab, though. Now that you're connection is configured, you can click the Connect button on the main window. After you do so, you can select the connection in Network Connections and view its properties. You will get screen similar to the ones shown below in Figures O and P.
