VPN and LAN Switching: Setting Up a VPN with Multiple Routers and 100+ Hosts

VPN and LAN Switching: Setting up a VPN with Multiple Routers for 100+ Hosts

In this article, we will discuss how to set up a VPN (Virtual Private Network) with multiple routers for a LAN (Local Area Network) of 100+ hosts. This guide will provide a detailed explanation of the key concepts and steps involved in the process, with subtitles and code blocks to help illustrate each point.

Setting up the Network

Before we begin, it is important to note that the LAN in this example consists of 192.168.0.1 to 254. The ISP (Internet Service Provider) has provided two routers for this network: one regular internet router and one access Huawei VPN router. The regular internet router will be used for DHCP (Dynamic Host Configuration Protocol) and NAT (Network Address Translation) purposes, while the VPN router will be used to establish the VPN connection.

Configuring the Regular Internet Router

To configure the regular internet router, follow these steps:

1. Connect the regular internet router to the modem provided by the ISP.
2. Log in to the router's web-based management interface.
3. Set the router's IP address to 192.168.0.254.
4. Set the DHCP server to assign IP addresses in the range of 192.168.0.100 to 192.168.0.200.
5. Enable NAT to allow the LAN hosts to access the internet through the router.

Configuring the VPN Router

To configure the VPN router, follow these steps:

1. Connect the VPN router to the regular internet router using an Ethernet cable.
2. Log in to the VPN router's web-based management interface.
3. Set the router's IP address to 192.168.0.253.
4. Configure the VPN connection settings, such as the VPN server address, VPN user name, and VPN password.
5. Enable the VPN connection and verify that it is working properly.

Configuring the LAN Hosts

To configure the LAN hosts, follow these steps:

1. Connect each host to the regular internet router using an Ethernet cable or Wi-Fi.
2. Configure each host's network settings to use the regular internet router as its default gateway and DNS server.
3. Configure each host's VPN settings to use the VPN router as its VPN server and specify the VPN user name and password.

Verifying the Setup

To verify that the VPN and LAN switching setup is working properly, follow these steps:

1. Ping the regular internet router's IP address (192.168.0.254) from a LAN host.
2. Ping the VPN router's IP address (192.168.0.253) from a LAN host.
3. Ping a remote host on the internet from a LAN host.
4. Check the VPN connection status on the VPN router.

In this article, we have discussed how to set up a VPN with multiple routers for a LAN of 100+ hosts. This process involves configuring the regular internet router for DHCP and NAT, configuring the VPN router for the VPN connection, and configuring the LAN hosts to use the VPN connection. By following these steps, you can ensure that your LAN is secure and can access the internet through the VPN.
