Before you start
Record advertised client endpoints, TCP and UDP allocations, file destinations and administration access. Identify the origin and any proxies. Keep artifact and resource versions, file backups and a consistent database copy. Arrange maintenance and a recovery access method before restricting the origin.
Map the traffic in your installation
Start with the actual configuration and panel-assigned ports. Separate gameplay, txAdmin, file services and external services. Record protocols and destinations instead of copying a list of default ports. A custom allocation remains the reference for your instance.
Also check domain addresses, old public addresses and endpoints advertised by FXServer. A secondary service may expose the origin even when the main link uses a proxy. Use this inventory to establish the scope with the provider.
Combine HTTP proxying with gameplay protection
The HTTP connection proxy and downloads serve a different role from gameplay transport. Cfx documentation distinguishes these paths; a working web proxy does not certify protection of UDP traffic. Establish what is filtered, relayed or left directly reachable.
If you use a file cache, check destinations and access conditions. Proxy and file settings depend on the FXServer version. A setting in newer documentation may be absent from an older artifact: confirm availability before changing configuration.
Restrict the origin with a rollback method
A directly reachable origin can allow protection bypass. Before restricting it, validate legitimate sources, return routes and each service protocol. Include downloads, voice and monitoring. Test a complete connection with a recovery configuration available.
Keep precise, documented trusted-source lists. A global allowance or incorrect proxy address can undermine protection; a misplaced block can stop players joining. Rotating an IP or port does not replace origin protection, and should not be described as automatic without a delivered mechanism.
Secure txAdmin and sensitive access
Use individual administration accounts, strong secrets and permissions appropriate to each role. Revoke former access and avoid sharing a primary account. Backups, configuration files and logs can hold credentials, so protecting them is part of securing the server.
Do not expose a database or administration tool publicly without an identified need and appropriate controls. The hosting panel and txAdmin are separate environments; protecting one does not guarantee the security of the other. Maintain software and review access after team changes.
Validate events and scripts on the server
Network filtering cannot repair a game event that trusts client-supplied values. Resources must validate permissions, expected state and relevant values on the server before performing sensitive actions. Avoid expensive calculations or writes that can be triggered without controls.
Monitor repeated errors and operations that become costly under load. Test changes on a copy, retain previous versions and manage dependencies. Frameworks and resources require maintenance; adding protection does not automatically make scripts safe.
Prepare validation and incident handling
After a change, test normal connection, resource downloads, entering the game and essential functions from representative networks. Compare logs and measurements at matching times. Decide in advance how to restore a working configuration.
During an incident, retain the time, affected networks, messages and available mitigation events. Distinguish saturation, false positives, resource faults and administration errors. Coordinate active tests with the provider rather than sending improvised load traffic to production.
For your situation
| Situation | Next check |
|---|---|
| Managed FiveM hosting | Use the ports and tools actually supplied by the panel. Establish protected protocols and keep resources and access maintained. |
| Remote FiveM protection | Validate HTTP and UDP paths, files, voice and origin restrictions. Confirm proxy or tunnel prerequisites. |
| Expensive scripts or events | Fix server-side controls and measure affected operations. Network protection does not replace validation of game actions. |
