Problem mit Simutrans server public announcement

Code:
###################################network stuff##############################

#

# Synchronized networking is always a trade off between fast response and safe

# connections. A more relaxed timing will cause delay of commands but is more

# likely to compensate for clients running slightly faster than the rest.

#

 

# Sets the local addresses Simutrans should listen on and use for making outgoing connections

# By default it will use all local IPv4 and IPv6 addresses

# This setting has no effect if Simutrans has been compiled with the USE_IP4_ONLY flag set!

# The addresses listed will be tried in the order specified

# A DNS name may be specified, this will be resolved and Simutrans will attempt to listen

# on all of the addresses returned.
