Setup vpn access server 2003

First, are two communications devices enabled at the server? At least one of them should be a network adapter.

After all, the point of a remote access VPN is to provide access to internal network resources from outside the organization. To provide users with access to resources on the internal network via a VPN connection, you must distribute IP addresses to them. Allowing and restricting access Any type of remote access to a network opens up the potential for abuse and unauthorized access, although you can take steps to mitigate these risks. In addition, you can create strict policies, such as time of day restrictions, maximum session times, and MAC address restrictions, at the server to reduce the inherent security risk.

Network adapters are really cheap and separation makes the connections easier to secure. In this example, I've selected the second local area network connection see Figure D , a separate NIC from the one that connects this server to the network.

Notice the checkbox labeled "Enable security on the selected interface by setting up Basic Firewall" underneath the list of network interfaces. It's a good idea to enable since option it helps to protect your server from outside attack. A hardware firewall is still a good idea, too. With the selection of the Internet-connected NIC out of the way, you need to tell the RRAS wizard which network external clients should connect to in order to access resources.

Notice that the adapter selected for Internet access is not an option here. Just like every other client out there, your external VPN clients will need IP addresses that are local to the VPN server so that the clients can access the appropriate resources. Second, you can have your VPN server handle the distribution of IP addresses for any clients that connect to the server. To make this option work, you give your VPN server a range of available IP addresses that it can use. This is the method I prefer since I can tell at a glance exactly from where a client is connecting.

If they're in the VPN "pool" of addresses, I know they're remote, for example. So, for this setting, as shown in Figure F below, I prefer to use the "From a specified range of addresses" option. Make your selection and click Next. If you select the "From a specified range of addresses" option on the previous screen, you now have to tell the RRAS wizard exactly which addresses should be reserved for distribution to VPN clients.

To do this, click the New button on the Address Range Assignment screen. Cause : The name of the client computer is the same as the name of another computer on the network. Solution : Verify that the names of all computers on the network and computers connecting to the network are using unique computer names. For more information about how to turn on the remote access server, see the Windows Server Help and Support Center.

For more information about how to configure ports for remote access, see the Windows Server Help and Support Center. For more information about how to view properties of the remote access server, see the Windows Server Help and Support Center.

To do so, click Ports in Routing and Remote Access. Cause : The VPN client and the VPN server in conjunction with a remote access policy aren't configured to use at least one common authentication method.

Solution : Configure the VPN client and the VPN server in conjunction with a remote access policy to use at least one common authentication method. For more information about how to configure authentication, see the Windows Server Help and Support Center. Cause : The VPN client and the VPN server in conjunction with a remote access policy aren't configured to use at least one common encryption method. Solution : Configure the VPN client and the VPN server in conjunction with a remote access policy to use at least one common encryption method.

For more information about how to configure encryption, see the Windows Server Help and Support Center. Cause : The VPN connection doesn't have the appropriate permissions through dial-in properties of the user account and remote access policies.

Solution : Verify that the VPN connection has the appropriate permissions through dial-in properties of the user account and remote access policies.

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.

Also he can't get internet access from the local router. I tried a lot of cofigurations but can't solve the problem.

Maybe I need to configure Static Route? My server has one network adapter with these details: ip: With some routers, port remapping PPTP may only allow one user at a time. I would suggest contacting the router's manufacturer for more information.

Regarding VPN users can't access internal resources and just the server itself, it appears that 'routing' was not enabled during RRAS setup. Here are some links that may help you with the setup:. Updated: January 21,
