OpenVPN: How to reach a specific ip on client network side?

OpenVPN is a popular and secure virtual private network (VPN) solution that allows you to connect to a remote network securely over the internet. It provides a secure tunnel for your data to travel through, ensuring your privacy and protecting your information from potential threats. However, sometimes you may need to access a specific IP address on the client network side while connected to OpenVPN. In this article, we will explain how you can achieve this.

When you connect to a remote network using OpenVPN, your device is assigned an IP address from the remote network. This IP address is used to route your internet traffic through the VPN tunnel. By default, all your internet traffic is routed through the VPN, meaning that you can access resources on the remote network but cannot directly access devices or services on your local network.

To reach a specific IP address on your client network side while connected to OpenVPN, you need to configure your OpenVPN client and server appropriately. Here's how you can do it:

Step 1: Configure OpenVPN Server

The first step is to configure your OpenVPN server to allow access to the specific IP address on the client network side. This involves modifying the server configuration file. Here's what you need to do:

1. Open the OpenVPN server configuration file (usually located in the /etc/openvpn/ directory).
2. Add the following directive to the file, replacing "x.x.x.x" with the specific IP address you want to access: push "route x.x.x.x 255.255.255.255"
3. Save the configuration file and restart the OpenVPN server for the changes to take effect.

Step 2: Configure OpenVPN Client

Next, you need to configure your OpenVPN client to route traffic to the specific IP address through the VPN tunnel. Here's how you can do it:

1. Open the OpenVPN client configuration file (usually located in the config directory of your OpenVPN installation).
2. Add the following directive to the file, replacing "x.x.x.x" with the specific IP address you want to access: route x.x.x.x 255.255.255.255 vpn_gateway
3. Save the configuration file and restart the OpenVPN client for the changes to take effect.

Once you have made these configuration changes, you should be able to access the specific IP address on your client network side while connected to OpenVPN. Your internet traffic will still be routed through the VPN, but requests to the specific IP address will be directed to the client network instead of the remote network.

It's important to note that modifying the OpenVPN server and client configurations requires administrative access to the respective systems. If you are not familiar with server administration or are using a managed OpenVPN service, you may need to contact your system administrator or service provider for assistance.

By following these steps, you can easily reach a specific IP address on your client network side while connected to OpenVPN. This can be useful when you need to access devices or services on your local network while connected to a remote network securely.
