Server 1
CONNECTIVITY FEATURE
HaruHost Tunnels - a public server in seconds
Skip the firewall setup, CGNAT issues, and manual port forwarding that usually turn self-hosting into hours or days of headaches. The in-app how-to-connect guide prepares the tunnel automatically and leads you through the exact steps needed to get connected.
Best for
Home-hosted servers, CGNAT, and setups where normal port forwarding is the blocker.
Outcome
A cleaner route from “server is running” to “players can actually join.”
Next step
Use the matching guide for the game so the final in-game join flow stays accurate.
How It Works
How Game Server Tunneling Works
A tunnel gives your server a public path through HaruHost, so players connect through the relay instead of trying to reach your home network directly. That helps avoid the usual blockers around firewalls, routers, and public IP setup.

Frequently Asked Questions
Tunnel-specific frequently asked questions.
Quick answers for the most common questions around CGNAT, reachability, home IP exposure, and relay-based connection flow.
The non hosting related answers are intended as general guidance for common Tunnel questions. Exact behavior can vary by game, server setup, and future product changes.
What is HaruHost Tunnel?
HaruHost Tunnel is a built-in reachability feature for supported servers. Your server still runs on your own machine, while HaruHost provides the public connection path that players join through.
Why would I want to use a HaruHost Tunnel?
The main reason to use HaruHost Tunnel is that it can save hours or even days of firewall, port forwarding, and general reachability headaches. Instead of manually configuring each layer yourself, Tunnel gives supported games a simpler path that makes the server just work.
It is also easier to control. You can turn the Tunnel off or on inside HaruHost whenever you need to. Manual firewall rules and port forwarding rules usually stay open until you remove them yourself.
How do I enable a Tunnel?
Open the game server page and press How to connect. For supported servers, HaruHost will guide you through the flow and set up the Tunnel for you. It is the easiest way to get started.
Does HaruHost Tunnel host the game server?
The game server continues running on your own self-hosted hardware. HaruHost Tunnel does not host, move, or transfer the server to HaruHost infrastructure. It only provides the network path that allows players to connect to the server running on your hardware.
Does HaruHost Tunnel help with CGNAT?
Tunnel is designed for cases where CGNAT or similar network limits make normal direct reachability difficult. Instead of relying on direct inbound access to your home network, the server connects outward through HaruHost.
Do I still need port forwarding if I use Tunnel?
Port forwarding is generally not needed when using Tunnel. One of the main reasons to use it is to avoid the usual manual router port forwarding setup for supported games.
Do I need to set up firewall rules if I use Tunnel?
Firewall setup is generally not needed when using Tunnel. One of the main reasons to use it is to avoid the usual manual firewall and router setup for supported games.
Does Tunnel hide my home IP?
When you use a Tunnel, HaruHost Relay provides a relay address for your game server, allowing players to connect through that address instead of directly to your home IP. In that sense, your home IP is not directly exposed to people connecting through the relay — the relay IP is.
However, this does not guarantee that your real IP is completely hidden or untraceable. Depending on how the game server or its plugins/tools are implemented, your real IP could still be exposed to external services or even to clients in some cases.
So the most accurate answer is: a Tunnel can make your home IP harder to trace, but it does not guarantee full IP masking. If you need stronger privacy protection, a VPN is usually the better solution.
Think of a Tunnel as giving your server an additional public address to connect through, rather than as a complete anonymity or IP-hiding solution.
Can I switch the relay regions?
Yes. You can select any of the available relay regions, but it is generally recommended to choose the one closest to you or your players for the best latency.
Does HaruHost provide unlimited bandwidth?
HaruHost does not provide unlimited bandwidth because it does not have unlimited bandwidth resources. The Tunnel feature is currently experimental, and specific per-plan bandwidth ceilings are in place and monitored to keep traffic fair. For most game servers this usually should not be a concern because game server traffic itself is relatively small, unless you are running a very highly populated server.
Can Tunnels in HaruHost be used for things other than game servers?
HaruHost Tunnel is only for supported game servers. It is not intended for other uses.
How do I turn the Tunnel off?
Open the game server page, go to the Details tab, and use the Tunneling switch to turn it off or back on.
If someone DDoSes the tunnel address, who is affected?
If a DDoS attack targets the tunnel address, the attack is directed at the relay service, not directly at the machine using the tunnel. In other words, a tunnel connection means the relay receives the attack, not the user's own connection.
However, this does not mean the machine behind the tunnel is completely immune to DDoS attacks. That is a separate topic and can depend on many other factors, such as server configuration, other exposed services, or whether the real IP is known through other means.
So the most accurate way to put it is: if the tunnel address itself is attacked, the relay is the one affected, not the server behind it.
Who can see the traffic when using a Tunnel?
A Tunnel does not automatically provide end-to-end encryption. Traffic sent through a Tunnel is still subject to the same encryption properties as it would be without the Tunnel. In other words, if the game or application traffic is not encrypted, using a Tunnel does not make it encrypted — it simply adds another point in the route through which the traffic passes.
Does Tunnel increase latency?
Tunneling adds some latency because traffic goes through a relay region, but for most casual servers that added delay is usually negligible unless the chosen region is far away. More important is having a stable internet connection on the self-hosted side where the server is running.
