Hello everybody,
I don’t really know where to turn, but I thought in the Teamspeak forum that could be right because it is also Teamspeak specific:
I once put together a few firewall rules, but I have a little problem: Unfortunately the Sinusbot page was not accessible 
(sinusbot.mydomain.tld)
iptables -N SERVICES
iptables -A SERVICES -p tcp -m tcp --dport 53 -m comment --comment “Erlaube: DNS” -j ACCEPT

I quickly tinkered in the accounting port today so that I wouldn’t lose my license
