If I use iptable, I can't join and say me: Could not connect to a default or fallback server, please try again later: io.netty.channel.ConnectTimeoutException Code (Text): iptables -F iptables -X iptables -N bungee iptables -A bungee --src 1.2.3.4 -j ACCEPT #1.2.3.4 is my ip iptables -A bungee -j DROP iptables -I INPUT -m tcp -p tcp --dport 25566:25570 -j bungee And if I use IPWhitelist, it say me the playerKickMessage: "&cYou have to join through the proxy." Solved: I use OnlyProxyJoin
