Hello friends, my first time creating a teamspeak server and I'm having this problem, I'm not very experienced with linux.
My Virtual Private Server: Linux Ubuntu 14.04 Server X86
I follow this step to install the server:
r4p3.net
I tried this command but I did not succeed:
iptables -A INPUT -p tcp --dport 9987 -j ACCEPT
iptables -A INPUT -p udp --dport 9987 -j ACCEPT

My Virtual Private Server: Linux Ubuntu 14.04 Server X86
I follow this step to install the server:
