# IMPORTANT: If you are behind a firewall, to allow outside users to
#            connect to your server, you will need to:
# ----------
# 1. set the -clientPortStart and -clientPortEnd options below
# 2. configure your firewall to forward the specified UDP ports as well
#    as the contact port (15345/udp) to the XPilot server host

# Set OTHEROPTIONS to any additional options desired when the XPilot NG
# server starts, e.g.
#
# -timerResolution 100
#       This hack attempts to make the frame rate more accurate.
#       Without it, the server will be a fraction of a frame per second
#       slower than the specified value.  However, on a loaded system
#       (e.g. running the distributed.net client) it has been found
#       that -timerResolution is not effective, and ends up further
#       slowing down the framerate.
#
# -clientPortStart 40000 -clientPortEnd 40009
#       If the server is run behind an IP masquerading firewall which is
#       set up to port-forward a range of UDP ports to the server machine,
#       this pair of switches establishes that range of ports which is
#       used between each client and the server after a connection is
#       negotiated (as distinct from the XPilot NG server port, which
#       defaults to 15345/udp and is only used to initially establish
#       the connection).
