问题描述
我从没使用过iptables,而且在线文档似乎有点不透明.
I've never used iptables, and the documentation online seems a bit opaque.
除来自特定IP地址的请求外,我想阻止对服务器上端口8000的所有请求.如何使用iptables做到这一点?
I'd like to block all requests to port 8000 on my server except those coming from a specific IP address. How do I do that using iptables?
推荐答案此问题应该在服务器故障上.不过,假设您正在谈论TCP,而您要允许的IP是1.2.3.4,则以下方法应该可以解决问题:
This question should be on Server Fault. Nevertheless, the following should do the trick, assuming you're talking about TCP and the IP you want to allow is 1.2.3.4:
iptables -A INPUT -p tcp --dport 8000 -s 1.2.3.4 -j ACCEPT iptables -A INPUT -p tcp --dport 8000 -j DROP更多推荐
