I have the problem that I can not create a fully functionale TS3 Server while beeing connected with ethernet so not W-LAN just with a cable. I have done all the ports on my local Internet provider and I also added the ports on my Windows Firewall. My question here is if it is even possible to create a TS3 Server while beeing connected to your internt with just a cable and when it is is there any specific things you have to take into account before the TS3 Server can work properly?
In the attachaments you can see the ports I have on my provider and if they are TCP or UDP and in the other attachment you can see the ports I have added.
