我有一台新服务器,但对 iptables 不太确定。我试过打开端口(25565,如下所示),但仍然无法连接。iptables -L 说明如下;
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:25565

我认为这与拒绝与 icmp-host-prohibited 有关,但我真的不知道这意味着什么。
关闭 iptables 允许访问,因此问题不是正在运行的服务。
提前致谢!
接受的规则应该在拒绝一切的规则之前添加到 INPUT 链中。
以下应该工作:
iptables -I INPUT 4 -p tcp --dport 25565 -j ACCEPT

如果有效,请清除您的 OUTPUT 链并保存您的 iptables 设置:
iptables -F OUTPUT
/etc/init.d/iptables save
