Hamachi - Virtual LAN

Hamachi is a VPN tool by LogMeIn that creates virtual local networks over the internet. You and up to four other people (on the free plan) get connected as if you were on the same LAN. The main reason people install it is to play older games that only support LAN multiplayer - Hamachi tricks the game into thinking everyone is on the same local network.

It also works for remote file sharing and accessing computers on a private network without setting up port forwarding or messing with your router. The free version supports up to 5 computers per network. Paid plans go up to 256.

What it does

Create a network (Network > Create a New Network), pick an ID and password, and share those with whoever needs to join. Each computer gets a virtual IP address in the 25.x.x.x range. Once connected, you can ping each other, share folders, use remote desktop, or host LAN game sessions as if you were in the same room.

The connection indicator next to each member tells you the status: green dot means direct tunnel, yellow means traffic is relayed through Hamachi's servers (slower), red means no connection. If you are stuck on relay, it usually means a firewall is blocking the direct connection.

Advantages

  • Simple setup for LAN gaming over the internet
  • No router configuration or port forwarding needed
  • AES 256-bit encryption
  • Works on Windows, Mac, and Linux

Drawbacks

  • Free version limited to 5 computers per network
  • Connections sometimes fall back to relay mode, which adds latency
  • Radmin VPN and ZeroTier offer similar features with higher free limits
  • Tailscale is a more modern alternative using WireGuard

Who it is for

Hamachi is mostly used for LAN gaming with friends who are not on the same network. If you need more than 5 connections for free, Radmin VPN or ZeroTier are better options. For anything more serious than gaming, Tailscale or WireGuard are worth looking at.

How do I play LAN games with Hamachi?
