# WHATPORT(1119)

## NAME

port 1119 — Battle.net (bnetgame) — Blizzard's Battle.net chat/game protocol — an outbound port your games use, not something that listens on your machine.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registers 1119 as bnetgame, "Battle.net Chat/Game Protocol". Blizzard's client stack uses it for the Battle.net connection behind titles like World of Warcraft, StarCraft II, Diablo III and Overwatch, which is why home firewall and router guides list TCP 1119 as one of the outbound ports to permit. On a desktop this is a connection going out to Blizzard's servers; a host listening on 1119 is not a Blizzard client and should be identified.

## EXPOSURE

**Fine to expose.** Allowing outbound TCP 1119 is normal for a machine that plays Blizzard games. Nothing on a home or server network should be accepting inbound connections on it.

## CHECK

```sh
sudo lsof -nP -iTCP:1119
```
