For organizations managing multiple advertising accounts or e-commerce storefronts, sharing a single IP address carries a high risk of collateral bans (chain-bans). SoftEther VPN Server Multi IP is the optimal solution for establishing an Identity Isolation mechanism, assigning each user a unique, static Public IP on the same server system.

Automated Installation (Quick Setup)

You can deploy an advanced SoftEther VPN Server Multi IP system using just a single command via the SoftEther VPN Server Multi IP Auto Installer Script developed by VietHosting

BASH / TERMINAL
curl -O https://mirrors.viethosting.com/scripts/softether-installer-multi-ip.sh && bash softether-installer-multi-ip.sh

The tool automates the entire process: provisioning Virtual Hubs, configuring Local Bridges, setting up 1:1 SNAT routing, and managing intelligent IP allocation.

1. What is the SoftEther VPN Server Multi IP Auto Installer?

The SoftEther VPN Server Multi IP Auto Installer is an enterprise-grade Bash automation tool developed by VietHosting, designed to deploy a scalable Multi-IP VPN gateway on VPS or dedicated servers.

It implements a Virtual Hub + Subnet + 1:1 SNAT architecture, allowing each user group (or individual user) to operate under a dedicated public IP, ensuring full identity isolation and eliminating risks associated with shared IP reputation.

Key Features (Multi-IP Edition):

  • High Scalability: Supports up to 254 isolated Virtual Hubs, each functioning as an independent LAN using the 10.8.x.0/24 subnet architecture.
  • Identity Isolation: Each hub is assigned a dedicated Exit IP, ensuring that traffic is completely separated between users or systems.
  • 1:1 NAT Mapping (SNAT Architecture): Each private subnet is mapped to a unique public IP, creating fully independent network footprints with zero cross-contamination.
  • Automated Networking Stack: Built-in DHCP (via dnsmasq), routing, and NAT configuration — no manual network setup required.
  • SaaS-ready CLI Management: Interactive CLI menu allows:
    • Public IP allocation per user/hub
    • Instant VPN user creation
    • Automatic .ovpn export
    • Clean removal with rule garbage collection
  • Smart Firewall & SSL Automation: Automatically detects iptables or nftables, integrates with UFW/Firewalld, and provisions Let's Encrypt SSL for secure SSTP (HTTPS 443) tunnels.

2. Network Architecture After Installing SoftEther VPN Server Multi IP

Unlike the Single IP version, the Multi IP edition implements a complex network architecture designed to isolate user identities at the infrastructure level:

  • Identity Isolation Mechanism: Each user (or group) is hard-bound to a specific Public IPv4 address.
  • Virtual Hub Isolation: Automatically provisions and manages up to 254 independent Virtual Hubs on the VPN Server, each with its own internal network range.
  • Multi-Protocol per IP: Full support for L2TP/IPsec, MS-SSTP, and OpenVPN for every allocated IP address.
  • Automated Management: Automatically configures SNAT (Source NAT) and cleans up routing rules via a Garbage Collection feature upon account revocation.

3. Why Businesses Need a Multi IP VPN Server Solution?

This solution is specifically designed for businesses requiring absolute network footprint cleanliness and separation when operating a VPN Server:

Criteria Standard VPN Server (Single IP) SoftEther VPN Server Multi IP
Exit IP Address All users access the Internet via a single Server IP. Each user exits via a unique, assigned Public IP.
Collateral Risk One banned account may affect the entire system. Complete isolation; zero risk for other IPs.
Network Admin Potential identity confusion during parallel tasks. Strict control over User-to-IP Mapping.
Infrastructure Cost Requires buying multiple fragmented small VPS (Expensive). Leverage 1 powerful server with an IP Subnet (Cost-effective).

4. Deploying the System via SoftEther VPN Server Multi IP Auto Installer

The SoftEther VPN Server Multi IP Auto Installer script is optimized by VietHosting to handle the most difficult parts of Linux routing, ensuring safety with a professional file locking (flock) mechanism.

System Requirements

  • A Dedicated Server or Large VPS with additional IPv4 addresses pre-assigned.
  • Operating System: Ubuntu 20.04+, Debian 10+, or CentOS/Alma/Rocky 8+.
  • root access via SSH.
BASH / TERMINAL
curl -O https://mirrors.viethosting.com/scripts/softether-installer-multi-ip.sh && bash softether-installer-multi-ip.sh

5. Managing IP Allocation and Users via CLI

All VPN Server administrative tasks are performed through an intuitive CLI Menu. To manage, simply re-run:

BASH / TERMINAL
bash softether-installer-multi-ip.sh

Real CLI interface of SoftEther VPN Server auto-installer script - VietHosting

  • Add a new VPN User (Assign IP): The script lists available Public IPs on the Server. Simply select the IP index, and the system automatically programs the Virtual Hub and SNAT routing.
  • Revoke a VPN User: When deleting a user, the system terminates active sessions and automatically cleans up virtual network cards and firewall rules if the Hub is no longer in use.
  • List VPN Users & IP Maps: Displays an accurate statistics table of which User is assigned to which IP on the VPN Server.

6. Verifying User Identity Isolation

To ensure isolation works correctly, ask employees to access ifconfig.me after connecting to the VPN Server. If the returned IP matches the assigned dedicated IP (and differs from the server's primary IP), your Identity Isolation system is working perfectly.
