By default, UFW will block all of the incoming connections and allow all outbound connections. This means that anyone trying to access your server will not be able to connect unless you specifically open the port, while all applications and services running on your server will be able to access the outside world. 本文最先发布在： 如何在 Ubuntu 20.04 上使用 UFW 来设置防火墙防火墙是一个用来监视和过滤进出网络流量的工具。它通过定义一系列安全规则，来决定是否允许或者屏蔽指定的流量。. 1.关闭ubuntu的防火墙 ufw disable 2.卸载了iptables apt-get remove iptables. 1.用iptables -F这个命令来关闭防火墙,但是使用这个命令前,千万记得用iptables -L查看一下你的系统中所有链的默认target,iptables -F这个命令只是清除所有规则,只不会真正关闭iptables.想象一下,如果你的链默认target是DROP,本来你有规则来允许一些.

| interface string | Specify interface for the rule. The direction (in or out) used for the interface depends on the value of direction. See interface_in and interface_out for routed rules that needs to supply both an input and output interface. Mutually exclusive with interface_in and interface_out. | |
| interface_in added in 0.2.0 of community.general | Specify input interface for the rule. This is mutually exclusive with direction and interface. However, it is compatible with interface_out for routed rules. | |
| interface_out added in 0.2.0 of community.general | Specify output interface for the rule. This is mutually exclusive with direction and interface. However, it is compatible with interface_in for routed rules. | |
