tcp、udp:默认的链规则匹配条件只支持-sd(源/目的IP)、-p(协议)、-lo(网卡输入/输出接口),加载该模块后可以支持--dport、--sport匹配条件,使用模块对应的功能时通常需要携带-m mod参数,但该模块的使用可以不携带-m参数,iptables默认会根据-p指定的tcp/udp来隐式加载对应的模块。例,iptables -t filter -I ...
ufw route allow proto udp from any port 53 to any port 1024:65535 Because DNS is a very common service, so there is already a firewall rule to allow a bigger port range to receive DNS packages. The reason for choosing ufw-user-forward, not ufw-user-input using ufw-user-input Pro:...
