The example, shown below in Figure G , contains the username and password, which I provided. Before you hit the Connect button, take a little time to adjust the client settings. To do so, click the Properties button. I will go through most of the screens, and provide explanation where I recommend that you change the default settings.
There isn't much to change here, except if you need to change the name or IP address of the server to which you will connect. You can also configure this connection to dial a different connection before attempting to connect to the VPN.
This is useful for clients that need to establish a dial-up connection before connecting to the VPN as it reduces the number of steps the remote user must take to attach to your server. Also located on this tab is a checkbox that enables the network adapter icon to appear in the system tray whenever this connection is active. Short version: You don't need to make changes here if you provided all of the necessary information during the wizard. The Options tab provides choices for how to handle the initial connection and any subsequent redial attempts.
The word "dial" on this screen is a little misleading since the options aren't strictly for modem-only users. On this screen, you can dictate whether the system should provide you with information about the connection status and how user names, passwords and domain names should be handled. Further, you can tell Windows what to do if the connection is dropped—should it be automatically redialed or not, for example?
As you can imagine, this is where you specify security settings for the connection. If you set up your VPN server as per the instructions in the previous article, you shouldn't need to change these settings.
If you want to increase security, though, select the "Advanced custom settings " option and make sure those match your server setup. I won't be going into these options in this article, however. This article series' scope is simply to get a PPTP server up and running and accepting connections from clients. One option I never recommend that you enable is the "Automatically use my Windows logon name and password and domain if any " option since it can result in a big, gaping security hole.
Basically, if you forget to log out, or whatever, anyone that walks up to the client computer could connect to your organization's network and do what they will. It's not that much work to type a user name and password. 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.
Sample diagram below:. The next screen entitled VPN Connection, asks you to determine which network adapter is used to connect the system to the Internet. For VPN servers, a separate network adapter should be installed and used.
Select outside NIC which is connecting to the Internet. It will select what network your VPN client will access, which in this case is the private network. Click Next.

Before you try to ping from a computer on one subnet to the other NetA or NetB , type ipconfig at a command prompt. Start Network Monitor, and then on the Capture menu, click Networks. Try to ping the computer. If the ping is not successful, check the security and system logs. Also check the security log.
If the remote gateway is also a Windows Server node, remember that:. This gateway can route packets because routing is enabled in Routing and Remote Access. To view the Windows Server Resource Kit and other technical documentation, visit the following Microsoft Web site:. Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice.

Click to clear the Mirrored check box. Click to select the filter action that you just created. Click Close. If the Windows Server gateway is multihomed with two or more network adapters on the same external network or two or more networks that can reach the destination tunnel IP 3rdExtIP , the potential exists for the following: Outbound tunnel traffic leaves on one interface, and the inbound tunnel traffic is received on a different interface.
To avoid sending outbound tunnel traffic on the wrong interface, define a static route to bind traffic to NetB to the appropriate external interface: In the Routing and Remote Access MMC, expand your server tree, expand the IP Routing subtree, right-click Static Routes , and then click New Static Route. In the Gateway box, type 3rdextip. Click Close , and then click OK. Start the IP Security Monitor tool. Need more help? Expand your skills.
