VPN Gateway

A VPN Gateway establishes an encrypted site-to-site connection between a Network on LANIT Cloud and a remote network (a data center, an office, or another cloud provider). Once the tunnel is up, your virtual machines on LANIT Cloud talk to remote hosts as if they were on the same private network — over IPsec on the public Internet.

One gateway per account

Each LANIT account can create only one VPN Gateway. On that single gateway you can configure multiple IPsec connections to different remote peers.

When to use a VPN Gateway

ScenarioGood fit?
Connect an on-premise office to virtual machines on the cloud
Hybrid cloud — extend an existing data center onto LANIT
Replicate a database across two regions (LANIT ↔ AWS / GCP)
Remote workers accessing internal VMs△ prefer a client-to-site VPN (OpenVPN/WireGuard inside a VM)
Exposing SSH/RDP to one or two users✗ a Security Group with IP restrictions is enough

VMs

The VPN Gateway owns its own Public IP allocated by LANIT. On the remote side you need an IPsec-capable device (Cisco ASA, MikroTik, pfSense, FortiGate, Linux strongSwan…) configured to peer with that Public IP.

Left / Right convention

LANIT follows the strongSwan convention:

  • Left = this side (LANIT Cloud).
  • Right = the remote side (the peer).
