Home Internet DDoSed After Hosting a Game Server? What to Do

If your whole home internet drops out whenever a certain player is upset, or right after you post your server address, you are probably being hit by a DDoS attack aimed at your public IP. The attack hits your connection itself, so no router or firewall setting at home can block it. The fix is to shut the server down, get a new public IP from your ISP (or by changing the router's WAN MAC address on some cable connections), report it to your ISP, and then only bring the server back behind something that hides your home address.

Signs it is a DDoS, not a normal outage

The internet for the whole house dies, not just the game, and comes back when the attack stops, often after a few minutes to an hour.
It lines up with game events: a player getting banned, a raid, a wipe announcement, an argument in voice chat.
Your modem shows it is online and synced, but nothing loads, or speed tests fail.
The router's traffic graph shows huge download usage while nobody in the house is downloading.
Your ISP's outage page shows no problem in your area.

A one off drop with none of these signs is more likely an ordinary outage. Repeated drops tied to the server are the giveaway.

Why your router cannot stop it

A DDoS floods your connection with more traffic than it can carry. By the time the traffic reaches your router, the line from your ISP is already full. Router firewalls, "DoS protection" checkboxes and Windows Firewall only filter traffic that has already arrived, which is too late. Real protection happens upstream, on networks big enough to absorb the flood, which is what game hosts and DDoS protection services do. Our DDoS protection explainer covers how that works.

Step 1: take the target away

Stop the game server.
Remove the port forwarding rules so nothing at home answers on those ports.
Take the address off any public listing, Discord channel or website.

The attack targets your IP, not the server, so this alone does not end it. It does stop you feeding the attacker information (for example, seeing the server come back online).

Step 2: get a new public IP

This is what ends it. Ways to change your public IP, depending on your ISP:

Ask the ISP. Call support, explain that your IP is under attack, and ask for a new public IP. Many ISPs can do it on the spot. This is the most reliable route.
Leave the modem unplugged. On many cable and DSL connections, unplugging the modem for several hours (sometimes overnight) lets the lease expire, and you get a new address when it reconnects. Not guaranteed.
Change the router's WAN MAC address. On cable ISPs where your own router talks to the modem, the IP is often tied to the router's MAC. Many routers have a MAC clone or MAC address option on the WAN settings page. Change it, restart the modem and router, and you usually get a new address. ASUS, Netgear and TP-Link routers all have this option.
Fiber and PPPoE connections often give a new IP on reconnect. Reconnect the WAN in the router.

Confirm by searching "what is my IP" and comparing with the old address.

Step 3: report it

Tell your ISP. They can see the attack traffic and sometimes filter it upstream. Repeated attacks on a residential line are also something they will want to know about, rather than finding out from their own monitoring.
Save evidence. Screenshots of drops, times, player names, any threats. DDoS attacks are illegal in many countries, including the US and UK. If someone threatened you or the attacks continue, report it to local police or the relevant cybercrime reporting service.
Ban the suspect from the server and your community spaces, but do not tell them why or when.

Step 4: find out how they got your IP

When you host at home with port forwarding, everyone who joins can see the server address, which is your home IP. Other leaks:

Posting the address in a public Discord, forum or server list.
A DDNS hostname that resolves straight to your home IP.
Peer to peer voice chat or game features that connect players directly.
Server admin tools or plugins that show IPs to moderators.

Any of these is enough. It does not take hacking skill; it takes one angry player and a few dollars for a "booter" service.

Step 5: come back without exposing your IP

If you bring the server back the same way, the same thing can happen with your new IP. Safer options:

A tunnel such as playit.gg. Players connect to playit's address, and your home IP is not shown to them. See playit.gg game server setup.
A private virtual LAN (Tailscale, ZeroTier) for trusted friends only. Nobody outside the group can reach the server at all. See Tailscale for game servers.
A hosted server. The server's address belongs to a data center with DDoS protection in front of it. Your home IP is never involved.
Private server only. Password, whitelist and no public listing reduce the chance of a stranger joining. See how to make a game server private.

What does not help

A VPN on your PC. It hides your IP when you browse, but your home connection is still the server's address if you port forward.
Changing the game's port. The attack targets your IP, not a port.
Router "DoS protection" settings. They stop small floods and port scans, not a full DDoS on your line.
Buying faster internet. Attack traffic can easily exceed any home plan.

A scene from Rust

Keep the attacks away from your house

The surest way to stop your family's internet going down over a game is to move the server off your connection. A GamezServers server has its own address and always on DDoS protection, so an attack is aimed at a network built to absorb it, not your home line. It is live about a minute after checkout for most games, and you can upload your existing world. See Rust hosting.

FAQ

Can someone DDoS me from my game server?

Yes, if players can see your home IP, which they can when you host with port forwarding. They target your internet connection, not the game.

Will restarting my router stop a DDoS?

Not usually. The attack continues on the same IP. You need a new public IP, which a router restart alone rarely gives you.

How long does a DDoS attack last?

Most attacks on home connections last minutes to an hour, but they can repeat for days if the attacker keeps your IP.

Is DDoSing a game server illegal?

In many countries, including the US and UK, launching a DDoS attack is a crime. Keep evidence and report persistent attacks.
