How to set up the server and connect

Extract the contents of the client archive into your game folder (where Fallout3.exe is located). Run vaultmp/vaultmp.exe or vaultmp/vaultmpd.exe and query the master server to get a list of online servers. If you can't see any servers then there likely is none online. Check the forums / main page for news.

If you want others to be able to connect to your dedicated server (from the internet), you have to forward port 1770 (default) in your router configuration and in your firewall (or define an exception). The server ships with a configuration file (vaultserver.ini) which you can edit in order to customize your server.

General settings:

master	Address of the master server (IP:port). The port is optional. Defaults to "vaultmp.com"
port	The port the server will listen on. Defaults to 1770
host	The IP address to listen on
query	Can be either 0 or 1. Enables direct server query. Defaults to 1
players	Number of player slots. Defaults to 4
spawn	Determines the spawn cell of new players (hexadecimal cell ID). Defaults to Vault101Exterior (Fallout 3) and Goodsprings (New Vegas)
fileserve	Can be either 0 or 1. Enables file downloading from the server. Defaults to 0
