Network & ports

Each server gets a public IPv4 address and primary public port assigned during setup. The Network tab is the source of truth for the address your players should use.

Common game ports

• 25565/tcp — Minecraft Java internally. Your public port may be different; use the Network tab.
• 28015/tcp/udp — Rust game traffic.
• 28017/udp — Rust server browser query.
• 7777/udp — Satisfactory game traffic.
• 24454/udp — voice chat plugins (Simple Voice Chat, Plasmo Voice).
• 8123/tcp — Dynmap web view (only if you install it).

• 34197/udp - Factorio game traffic.
• 8211/udp - Palworld game traffic.
• 27015/udp - Palworld query traffic.

Discord bots do not expose a public game port by default.

Minecraft Bedrock crossplay

Bedrock crossplay through Geyser uses UDP. Use the Network tab as the source of truth:

• Server Address: the public IP shown under Bedrock server address.
• Port: the Bedrock UDP port shown by Kyrbit.

Do not assume the Bedrock port is 19132 or the same as the Java port. Some servers listen internally on 19132 while Kyrbit exposes a different public UDP port. Players should use the Bedrock port shown in the panel.

Custom ports

Kyrbit assigns one primary port per server. Dynmap can be opened from the server Network tab through a dashboard-hosted Kyrbit page while the plugin listens on 8123/tcp inside the server. If you need a raw extra public port, such as Simple Voice Chat on 24454/udp, open a support ticket and we'll add it deliberately.

Firewall

Kyrbit networking is restricted by default. Only ports we explicitly expose or relay through an authenticated dashboard route are reachable from outside. Plugin ports that bind to localhost are not directly reachable from the public internet, by design.

RCON

Minecraft RCON is not exposed publicly, ever. Use the panel console instead — it's the same thing, with auth that isn't a single shared password. Rust RCON is set up for Kyrbit management and should not be shared with players.
