DayZ Standalone DDoS Protection
This legacy page is kept for existing links. The current VxShield dashboard workflow is documented in the VxShield Firewall Guide.
VxShield is default closed. If you want your DayZ server to be reachable, each public DayZ port must be added in VxShield with the correct protocol and filter.
DayZ Ports and Filters
Section titled “DayZ Ports and Filters”DayZ commonly uses separate ports for game traffic, Steam query traffic, and RCON. Each port should be added separately unless you use the DayZ preset.
| Purpose | Common port | Protocol | Filter |
|---|---|---|---|
| Game traffic | 2302 | UDP | DayZ |
| Steam query | 2303 or 27016 | UDP | A2S Query Cache |
| RCON | 2305 | UDP | Generic UDP Rate Limiter |
If your DayZ server uses custom ports, use your configured ports instead of the common examples above.
