Soft Router- A Guide to Soft Routing

Soft router is gaining traction as one of the most efficient bandwidth management techniques. Today, managing network services is easier than ever with the soft router system for many companies. 

So what is soft routing, and what are some of the Open Source Router OS options? 

Join us as we explore everything about soft routing in this comprehensive guide.

We will cover all the key insights of this routing solution and the wide range of its applications in facilitating access across networks. 

What is a Soft Router?

A conventional network switch 

As the name suggests, it's similar to the conventional hardware router.

However, unlike hard routing, where there's a hardware component, soft routing involves wireless access to a network via software. 

Soft routing software can run either on a desktop or a server.

It enables access control to a router, eliminating the need for sophisticated hardware devices. 

Features of Soft Routering

A soft router offers multiple access methods, unlike hard routers. 

Among the key properties of soft routering systems include the following:  

1. A robust firewall function and efficiency in bandwidth management.
2. It guarantees email security and resistance to cyber threats and can block illegal websites, thus avoiding legal risks. 
3. Also, they come with multiple access methods and high work efficiency. 
4. A user-friendly management interface and reduced network management expenses. 

Advantages and Disadvantages of Soft Routing

You can set up a soft router on any PC.

Best Open Source Router OS Software

Here are the 13 great open-source router OS:

VyOS

VyOS router OS guarantees high-performance routing for all types of networks. It is primarily through supporting dynamic routing protocols that include 

• RIPng
• OSPF
• BGP
• Policy-based routing. 

Also, only internal users can access internal resources as it blocks out unauthorized users via stateful firewalls. 

RouterOS from MicroTik

RouterOS from MicroTik works on the Linux kernel.

It is the operating system for MicroTik router board hardware, which functions on the Linux kernel.

The open-source router OS comes with a wide range of features, such as: 

• Source firewall
• Bandwidth management
• Backhaul link
• A VPN server
• Hotspot gateway. 

RouterOS is also renowned for its wireless access point and other network services.

It's among the most popular systems owing to its ease of installation and user-friendly interface.  

OpenWRT

The OpenWRT software targets embedded devices and allows users to customize the router firmware.

Among its key upsides is access to numerous routing capabilities. It is similar to having numerous network ports in the conventional hard router. 

Accessing networks on OpenWRT is cost-efficient as this is free, open-source software.

Advanced Tomato

It is an open-source GUI-based router software that operates on Broadcom-based routers. The software allows you to perform a variety of operations that include: 

• Running custom scripts
• Access to a bandwidth usage monitor to manage internet connections
• Network port forwarding 
• Ability to perform a wireless site survey
• Access to  wireless client modes and WDS 

Note: The primary downside to this firmware is that its developers haven't updated it in years. 

Fresh Tomato

It's similar to Advanced Tomato as both are open-source routing firmware for Broadcom-based routers.

However, unlike Advanced Tomato, the Fresh Tomato firmware still receives updates from its programmers. 

Its other key upside is that access to router firmware is free. 

Others

The other open-source router operating systems include: 

• Pfsense software 
• ClearOS 
• IPFire
• DD-WRT
• Zeroshell
• Fli4I
• Sophos XG Home Firewall/Router
• OPNSense

Building a Home Soft Router and NAS with a ReComputer

Here's a stepwise illustration of how to build a home soft routing system and NAS. 

Hardware Assembly

You’ll need an SSD state solid drive disk.

Below are some of the key components you'll require and their specifications. 

• An 8GB RAM + 64GB eMMC ReComputer motherboard
• A m.2 SATA SSD
• Grove - OLED Display 0.96"
• Cooling fan- 8cm, 4-pin.
• An enclosure
• Fan cables, SSD cables, and grove cables. 

Note that acrylic sheets thickness < 3mm are best for the enclosure.

Most importantly, the cooling fan cables should be suitable for a 12V power supply. 

Assembly

1. 1. Connect the Grove - OLED Display 0.96" to the enclosure, then attach the cooling fan and 2.5" SSD. 
   2. Afterward, it would be best if you connected the 4-pin cooling fan. The four pins include the TACH pin, the PWM pins for connection to Arduino, the power supply pin, and the GND pin. 
   3. Next, link the Grove - OLED Display 0.96" to I2C, PWR, and the ground. 
   4. Now connect the SAMD21 serial port to the Intel CPU serial port, and once done, reconnect the front and rear lids of the enclosure. 

   Note that the fans enable cooling in this system by wafting cold air, which flows over the SSD and CPU cooling fans.

   The feature ensures that the heat dissipation of the system is super efficient. 

Proxmox VE Virtual Environment installation and configuration

You need an 8GB flash drive. 

• You need to install an open-source server management platform; in our case, we'll use Proxmox VE Virtual Environment. It requires an 8GB flash drive to install. Start by plugging in the USB drive with the program to the computer to install it.
• Press the F7 key numerous times to activate the boot device selection interface.
• Also, if you're having problems with the installation, consult the installation document for reference. 
• Note that the ReComputer features dual network ports. Let one of the ports be used exclusively in the management network of the PVE. Connect the remaining port to the soft router system's WAN port. 

Arduino Programs

Here is the Arduino Program that you will require to run this system:
