我当前正在尝试在Raspberry Pi 3B +上配置OpenVPN服务器。我通过IPTables打开了端口1194：
iptables -A INPUT -i $local -m state --state NEW,ESTABLISHED,RELATED -p udp --dport 1194 -j ACCEPT
iptables -A OUTPUT -i $local -m state --state ESTABLISHED,RELATED -p udp --sport 1194 -j ACCEPT
，我将同一端口从我的房子重定向到了木箱。不幸的是，您在帖子标题中看到的错误每次都会发生，我不明白原因。我已经搜索了很多帖子，但没有任何效果。 这是尝试连接时的完整日志：
