Network & ports

Each server gets a public IPv4 address and primary public port assigned at provisioning time. 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).

• 2456-2458/udp - Valheim game/session traffic.
• 34197/udp - Factorio game traffic.
• 8211/udp - Palworld game traffic.
• 27015/udp - Palworld query traffic.

Discord bot workloads do not expose a public game port by default.

Custom ports

Kyrbit assigns one primary port per server. If you need an extra exposed port (Dynmap, Bluemap, voice chat), open a support ticket and we'll add it. We don't auto-allocate extra ports during beta.

Firewall

Kyrbit networking is restricted by default. Only ports we explicitly expose are reachable from the public internet. Plugin ports that bind to localhost are not reachable from outside, 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 provisioned for Kyrbit management and should not be shared with players.
