Ts3 server on Ubuntu 18.04 with firewalld

TeamSpeak Server
1

Hello,

I have installed a new server with the structure Virtualmin/Webmin.

The TS3 server has its own user and is running.

The problem is, if firewalld is on, no connections to the TS3 Server are possible, even if I open the needed ports.

But if I turn off firewalld now, everything works fine.

Can anyone help me here ?

Thanks a lot.

Iā€™m not a linux pro but that should set a rule where traffic and port are free to use from outside

-A INPUT -p udp --dport 9987 -j ACCEPT

or when you use ufw

sudo ufw allow 9987/udp
