Project Zomboid

Project Zomboid is the ultimate in zombie survival. Alone or in MP: you loot, build, craft, fight, farm and fish in a struggle to survive. A hardcore RPG skillset, a vast map, a massively customisable sandbox and a cute tutorial raccoon await the unwary. So how will you die?

Server Ports

Project Zomboid requires one port for Steam and an additional one port per player. Additional ports are allocated as they connect.

For example, when configured with a base allocation of 27016:

Zomboid Steam Server started, ports 27016 and 27016 must be open on the router
Connected new client kubi ID # 0 and assigned DL port 27017
Connected new client kubi2 ID # 1 and assigned DL port 27018

If you're experiencing issues with players connecting it's likely because you have not allocated enough ports. These ports must be in order following the Steam port.

Port	default
Game	8766
Player1	8767
Player2	8768
...	8769
