Description

Business-VPN module WHMCS

 Order now | Download | FAQ

The Business VPN module provides an opportunity to sell the Virtual Private Network service for business clients.

The module is designed as a professional solution for companies and corporations, which enables remote access to company resources from anywhere in the world in a safe and monitored manner. The biggest difference from common VPN solutions such as NordVPN, EasyVPN etc. is the professional nature of the service.

 

What makes Business VPN different from regular, widely offered VPNs

The end customer of the service receives such opportunities as:

• Dedicated permanent IP address
• Full management of VPN accounts to the end buyer: Create, modify, delete and block VPN accounts
• Forward TCP/UDP protocol ports from a public address to any IP address on the internal network
• Convenient and informative VPN account connection statistics

Thanks to our solution, the client does not have to delegate the company's resources to carry out this activity, but focus on the practical side of using it, thanks to which he saves money.

This model of operation allows IT departments in companies to configure in detail and securely internal Firewall, passing specific ports, detailed traffic monitoring, or to keep through internal IDS which is not possible when using commonly offered solutions.
Such a VPN becomes an integral part of the company's IT infrastructure and is ideally suited to the conditions of a given client.

 

Who and why needs such a service that this module provides.

The service offers to the end customer a fully fledged private network.

1. The service combines all nodes that are connected via VPN into one private network. This allows you to communicate with each other from different physical locations. An example of use is, the remote work of the company's staff, having private remote access to each other.  Also, due to the fact that each connected VPN user will be presented on the Internet with the public address of the service, it is possible to configure access to the company's servers only from the IP address of the service. Thus restrict access only to everyone except users of the service.
2. If your employees need to have access to some sites on the Internet and be represented by a public address of a certain geographic location, then this service allows you to implement it. The public address of the service is not changed during the entire time of using the service.
3. Ability to connect network devices, such as measuring instruments, to the same network, creating remote access to network equipment.

 

Module Functions:

• Auto create and deploy VPN account/accounts
• Suspend/Unsuspend/Terminate/Change Package/Change Password/Reset connection
• Use only Mikrotik API
• Possibility to set Bandwidth speed limits
• Module supports multilingualism
• Account limit per package

Basic concepts and requirements

Requirements for the successful operation of the module

• Minimal WHMCS version 8+
• Mikrotik/CHR router OS 7+
• Public network for the needs of NAT implementation

An IP address class must be reserved for the solution. Each end customer receives one IP address after activating the service.

 

Please refer to the basic mode of operation of the module to better understand its operation and functionality.

The basic logic of the module

During the creation of a service for the end client, the module does the following actions:

1. Automatically selects a free public IP address from the server available in the settings. When choosing an available IP address, services in the terminated state are not taken into account, i.e. previously used IP. (Previously used IP addresses for services that have not been extended and have expired will be used to activate the service for the new client.)
2. The module configures the selected public IP address on the network interface of the router.
3. The module creates firewall rules such as:
   
   • NAT rules for accessing the Internet private network
   • Allowing firewall rules for communication between IP's of a private network
   • Block rules that block traffic between all other private networks.

Mikrotik management schema

• When a user creates a VPN account, the module creates a VPN user Mikrotik on the router, adds queues with a bandwidth limit.
• When a user deletes a VPN Account, the module deletes the VPN user on Mikrotik and deletes the bandwidth-limiting queue.
• When a user creates port forwarding, the module creates rules on the Mikrotik router in the firewall that implement port forwarding from a public address to a private one.
• During service suspension, the module disables all VPN client accounts and resets all active connections.
• During service unsuspension, the module enables all VPN client accounts.
• During service termination, the module deletes all VPN client accounts, deletes all firewall rules associated with the service, and also deletes the public IP from the router's network interface.
