Protect Your Game Servers
with Neurowall.

Keep game traffic available, prioritize legitimate players, and reduce unwanted network traffic before it reaches your servers. Neurowall combines firewall enforcement, eBPF/XDP acceleration, nftables policies, optional QoS, and OSSEC detection in one workflow.

How it works

One protection workflow.

A guided setup makes each proposed change visible before activation.

Neurowall shows whether each rule will be enforced through eBPF/XDP or nftables before anything is applied.

Capabilities

Built for game infrastructure.

Firewall Protection

Allow gameplay traffic from trusted clients and restrict unwanted networks. Keep SSH administrator access separate.

Fast Host Enforcement

When XDP is available, exact host-specific rules can be installed in the eBPF dataplane before traffic reaches the application.

Network-Level Policies

CIDR and broader network policies use nftables when they cannot be expressed as exact eBPF host tuples.

Optional QoS

Prioritize gameplay traffic with SQM/CAKE where supported. Existing enabled bandwidth profiles are reused rather than silently changed.

Safe Rule Ownership

Workflow-created rules are grouped and labeled, so protection for one server can be reviewed or removed independently.

Deployments

Designed for real deployments.

Review

See exactly what will be applied.

The review screen lists every important policy element before activation. No hidden rule generation and no silent truncation.

Boundaries

Understand the protection boundary.

Neurowall provides host and network-edge protection. It does not replace upstream volumetric DDoS scrubbing or provider-level traffic filtering.

When an attack saturates your uplinkCombine Neurowall with ISP, cloud, or upstream DDoS mitigation. Local filtering cannot recover bandwidth already saturated before traffic reaches the host.

FAQ

Frequently asked questions.

What does Neurowall Game Server Protection do?

It provides a guided workflow for firewall enforcement, optional QoS prioritization, and optional OSSEC detection for selected game servers.

Does every rule use eBPF/XDP?

No. Exact host rules may use eBPF/XDP when available. Broader CIDR and unrestricted rules use nftables, and the review screen shows the placement.

Does Neurowall stop attacks larger than my internet connection?

No. Attacks that saturate an upstream connection require mitigation from an ISP, cloud, or upstream provider.

Can I remove one server’s protection without affecting others?

Yes. Workflow-owned rules are grouped and labeled so they can be reconciled and removed per protected server.
