Connecting a Device to Another Subnet using a 3rd Device Proxy: A Solution for HTTPS Web Portal Access

Connecting to a Device on Another Subnet using a 3rd Device as a Proxy: Solution for HTTPS Web Portal Access

In today's interconnected world, it is common to encounter situations where you need to access a device on a different subnet. This could be due to various reasons such as network configuration, firewall settings, or physical limitations. In this article, we will discuss a solution for connecting to a device on another subnet using a 3rd device as a proxy, specifically for accessing an HTTPS web portal.

Understanding the Concept

When two devices are on different subnets, they cannot communicate directly with each other due to the way that IP addresses are structured. A proxy server can be used to facilitate communication between the devices by forwarding requests and responses between them. In this scenario, we will use a 3rd device as a proxy to access a device on another subnet that hosts an HTTPS web portal.

Prerequisites

Before we begin, ensure that you have the following:

• Three devices connected to the same network
• Access to the device that hosts the HTTPS web portal
• Basic knowledge of networking and HTTPS web portals

Steps to Connect to a Device on Another Subnet using a 3rd Device as a Proxy

Follow these steps to connect to a device on another subnet using a 3rd device as a proxy:

1. Identify the IP addresses of all three devices.
2. Configure the 3rd device as a proxy server.
3. Configure the device that you want to connect to the HTTPS web portal to use the 3rd device as a proxy.
4. Access the HTTPS web portal using the IP address of the device that hosts the portal.

Configuring the 3rd Device as a Proxy Server

To configure the 3rd device as a proxy server, follow these steps:

1. Open the web browser on the 3rd device.
2. Enter the IP address of the 3rd device in the address bar.
3. Log in to the device using your credentials.
4. Navigate to the network settings section.
5. Enable the proxy server feature.
6. Configure the proxy server settings, including the IP address and port number of the device that hosts the HTTPS web portal.

Configuring the Device to Use the 3rd Device as a Proxy

To configure the device to use the 3rd device as a proxy, follow these steps:

1. Open the web browser on the device.
2. Enter the IP address of the 3rd device in the address bar.
3. Log in to the device using your credentials.
4. Navigate to the network settings section.
5. Enable the proxy server feature.
6. Configure the proxy server settings, including the IP address and port number of the 3rd device.

Accessing the HTTPS Web Portal

To access the HTTPS web portal, follow these steps:

1. Open the web browser on the device.
2. Enter the IP address of the device that hosts the HTTPS web portal in the address bar.
3. Enter your credentials to log in to the portal.

Connecting to a device on another subnet using a 3rd device as a proxy can be a useful solution for accessing an HTTPS web portal. By following the steps outlined in this article, you can configure the 3rd device as a proxy server and connect your device to the HTTPS web portal. This solution can help you overcome network configuration issues, firewall settings, and physical limitations that may prevent direct communication between devices.
