Hosting a game server at home is reasonably safe for a small group of friends you trust, as long as you keep the server software updated, only open the ports the game needs, and only install mods from trusted sources. The main risks are that everyone who joins learns your home IP address, an open port is a door into your network if the software has a flaw, and a busy server can slow your household's internet. This guide explains each risk honestly and what you can do about it.
Short answer
| Risk | How serious for a friends server | How to reduce it |
|---|---|---|
| Your home IP is shared | Low with friends, higher with strangers | Only share with people you trust, or use a tunnel or host |
| Open ports | Low if the software is updated | Forward only the game's ports, keep the server patched |
| Malicious mods or plugins | Medium | Only install from well known sources |
| Someone attacks your connection | Low with friends, real on public servers | Keep the server private, or host elsewhere |
| Upload speed and household lag | Common | Wired connection, limit players, or host elsewhere |
| Electricity and hardware wear | A cost, not a danger | Use an efficient spare machine |
Risk 1: everyone who joins sees your IP
When friends connect to a server at home, they connect to your public IP address. Anyone with that address can find your approximate location (usually city or region, not your street) and your internet provider, and could try to flood your connection with traffic.
With a handful of real life friends, this is rarely a problem. It becomes one when the server address is posted publicly, shared in a big Discord, or listed in a public server browser, because now strangers have it too. Arguments in game have led to people knocking a host's whole household offline.
How to reduce it:
- Only share the address with people you know.
- Keep the server off public server lists.
- Use a tunnel service, which gives friends the tunnel provider's address instead of yours. See how to host a game server without port forwarding.
- Or run the server somewhere else, so your home IP is not involved at all.
Risk 2: open ports
Port forwarding opens a specific port on your router and sends that traffic to one PC. The port itself is not dangerous. The risk is the software listening behind it. If the server program has a security flaw, an attacker could use it to reach your PC.
This has happened. In 2021 the Log4Shell flaw in a common Java logging library affected Minecraft servers, and unpatched servers could be taken over by a crafted chat message. Mojang released fixes quickly, and servers that updated were safe.
How to reduce it:
- Forward only the ports the game needs. Never use a "DMZ" setting that exposes your whole PC.
- Keep the server updated. Updates fix security holes as well as bugs.
- Do not forward admin ports like RCON unless you really need them, and use a strong password if you do.
- Leave UPnP off unless you need it, since any program on your network can use it to open ports.
- Run the server as a normal user, not as an administrator, and ideally on a machine that is not your main PC with your personal files.
Risk 3: mods and plugins
Mods and plugins are code that runs on your PC. Almost all are fine, but malicious ones have been found in the wild, including Minecraft mods and plugins that stole browser data and login tokens.
How to reduce it:
- Download from the main platforms: CurseForge, Modrinth, Hangar and SpigotMC for Minecraft, Thunderstore for Valheim, the Steam Workshop, uMod or Carbon for Rust.
- Be wary of files sent directly in Discord or from unknown sites.
- Prefer popular, recently updated mods with a visible author.
Risk 4: griefers and uninvited players
If your address gets around, strangers can join and wreck builds. That is not a security risk for your PC, but it is a risk to your world.
How to reduce it: use a whitelist or password. On Minecraft set white-list=true in server.properties and add friends with whitelist add <name>. Most other games have a server password setting. Take regular backups.
Risk 5: your internet and your household
A game server uses your upload bandwidth, which on many home plans is a fraction of the download speed. Every player uses some of it. When someone in your house starts a video call or uploads files, the server lags, and when the server is busy, their call lags. Why is my game server lagging goes deeper.
Also check your internet provider's terms. Some residential plans technically do not allow running servers, though a small private game server is rarely noticed.
Risk 6: electricity, heat and wear
A PC left on around the clock costs money and runs warm. A gaming desktop might add roughly 10 to 20 USD a month to the power bill depending on hardware and local rates, and fans and drives wear faster when they never rest. Make sure the machine has airflow and is not tucked in a closed cupboard.
A safe home hosting checklist
- Use a spare machine if you can, not the PC with your personal files and logins.
- Reserve its local IP in the router and forward only the game's ports.
- Allow only those ports in the firewall.
- Keep the server and the operating system updated.
- Turn on a whitelist or password.
- Install mods only from trusted platforms.
- Keep the address private.
- Back up the world regularly to another drive.
The alternative: host it elsewhere
If you would rather not share your home IP or open anything on your router, the server has to run somewhere else. A hosted server runs on dedicated hardware in a data center, so friends connect to its address, not yours. There are no ports to forward, your household's upload is untouched, and the world stays online when your PC is off.
On GamezServers you pick a game and plan and the server is live in about 60 seconds. You still get the full console, a file manager and SFTP, so nothing is locked away. Split the bill with Split with friends at checkout and each person pays their own share: a 9.99 USD Minecraft server split 4 ways is about 3.50 USD each. More in game server hosting you can split with friends.
FAQ
Can people find my address from my game server?
They can see your public IP, which shows your approximate area and internet provider. It does not show your street address.
Is port forwarding dangerous?
Not by itself. The risk comes from outdated or flawed software listening on the forwarded port. Forward only what the game needs and keep it updated.
Can someone hack my PC through a Minecraft server?
It is rare with an updated server, but outdated software and malicious plugins have been used this way before. Keep the server patched and install plugins only from trusted sites.
Is it safer to use a hosting provider?
It removes the home specific risks: your IP is not shared, nothing is open on your router, and the server does not run on your personal PC.
Keep your home network out of it
Browse the games page to put your server in a data center instead. You can see everything you control in the control panel docs.
