Bridge

Warning !!! Bridge is only for advanced VPN system administrator.

• Purpose: Lets you use a remote LAN IP address, and you can use that IP to communicate with other machines in the remote LAN directly.
  
  
• Typical cases: I need to access our office LAN from an airport or other place, and also let remote LAN computers access my laptop.

VPN-X server on the Windows platform supports Bridge operation.

Network topology:

Note: You should have a very special LAN ip address to avoid conflicting with another local network. It’s a bad idea to use bridge mode with 192.168.1.0 or 192.168.0.0 network, because your coffee bar or airport local wireless network may also be using this network address.

The office LAN ip range: 192.168.100.1~254.
192.168.100.1~199 for real machine IPs
192.168.100.200~254 for VPN users.

The VPN-X Server LAN IP : 192.168.100.50
Gateway: 192.168.100.1
The public IP address for this LAN is : 61.173.25.162 (assumed)

After the network interface cards (NIC keep in mind, VPN-X is a Virtual NIC) are installed and connected, go to the bridging computer and open Control Panel, click Network and Internet Connections, and then click Network Connections.

Note: To create a network bridge you must select at least two network connections that are not being used by Internet Connection Sharing (ICS) or the Internet Connection Firewall (ICF).

Next click both network connections (if you have several segments, hold down the Ctrl key and click all the connections that correspond to all the LAN segments you want to bridge), right-click one, and then click Bridge Connections.

After the bridge configuration is complete, you'll end up with a Network Connections window that looks like the one below.

We should set the Network Bridge manually. Because we want to use the same IP address as the Local area connection setting: 192.168.100.50.

Right-Click the Network bridge and select the “Properties”, then select “Internet Protocol (TCP/IP)”, and change the IP address and gateway… click “Ok” and close all configuration windows.

Startup VPN-X server and change the VPN server setting as follows:
You should use the same network address to the VPN virtual Address as the LAN IP.

Click “Apply” to make your VPN server use the new settings.

Create a new VPN account in User Management Panel. The first account IP should be 192.168.100.201. The second account IP should be 192.168.100.202, and so on. You can change the IPs as needed, but you should make sure all VPN accounts’ addresses are in the same network, for example: 192.168.100.0  netmask  255.255.255.0

You can use the VPN account to login VPN-X from the remote VPN-X client.

Run this command on your client after client login:
Ping 192.168.100.1

If you receive a response, your VPN-X server with a Bridge office network is configured successfully.
Note: In this example, you should use 192.168.100.50 to access the VPN-X server.
Don’t use 192.168.100.200, because the “192.168.100.200” is a dummy address for starting the VPN account IP pool.
