- My advertising server does not show up in list at servers.openttd.org
- Run openttd with the '-d net=2' parameter, as this will show whether it

- is most likely that you need to configure your router to forward ports
- 3979 (both TCP and UDP) to the computer that is hosting the game.
+ Run openttd with the '-d net=2' parameter. That will show which incoming

+ communication from an admin tool reach the programme. See section 1
+ 'Starting a server' further up for the ports and protocols used by OpenTTD.
+ The ports can be configured in the config file.
