on my server is already running a teamspeak3 server with port 9987. Now i want to install another teamspeak server for my friend. Obviously i need to change to port. But i don’t know how. Can someone help me?
Have you a License for your TeamSpeak?
if you have a License and you have Admin Server Query, then you can create a second Server with a another Port via YatQa.
if not, then no you cant also run multiple instances on one vServer - one instance per IP address.
How many IP addresses you can create depends on the provider. I don’t have any recommendations about providers.
Is it possible to create a second server with a sponsered by teamspeak license?
You could also just use multiple docker container or VMs.
