multiport:该模块支持--sports、--dports匹配条件,允许指定多个不连续的端口号,增强了--sport/--dport匹配条件只能指定单个端口或连续端口的缺陷。 例,iptables -t filter -I OUTPUT -d 192.168.1.146 -p udp -m multiport --sports 137,138 -j REJECT; iprange:该模块支持--src-range、--dst-range匹配...

$ sudo ufw allow 1234/udp 允许一个IP段(IP range)访问 $ sudo ufw allow from 192.168.0.0/16 允许一个IP段访问特定的端口 $ sudo ufw allow from 192.168.0.0/16 to any port 3306 这就是ufw的常见用法了。
下面是一个简单的类图,展示了UFW和Docker之间的关系: Docker-id: string-name: string-ipAddress: string+getIpAddress() : stringUFW+install() : void+isActivated() : boolean+addRule(ipAddress: string, port: number, description: string) : void 结论 通过上述步骤,我们可以使用UFW来过滤Docker映射端口,...
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 ...
Previously we have added rules based onserviceorport. Ufw also allow you to add rules based onIP Address. Here’s the sample command. $ sudo ufw allow from 192.168.0.104 You can also use asubnet maskto wider the range. $ sudo ufw allow form 192.168.0.0/24 ...
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:...
7. Deny all UDP traffic to ports in range 8412:8500: # ufw deny proto udp from any to any port 8412:8500 8. Delete a particular rule. The rule number can be retrieved from the `ufw status numbered` command: # ufw delete rule_number ...
4.2. Enable Ports or a Range of Ports Without an Application Profile Suppose we’ve created a special-purpose server on a nonstandard port (55530/TCP), running concurrently with Apache.In this case, we don’t have an application profile. However, we can manually specify the rule: ...
sudo ufw allow from [IP_address] to any port [port_number]Copy The rule limits access to the specified port only. 5. Toallow access to a port range, specify the range values and the protocol type (TCPorUDP). For instance, the following command allows connections from ports 2000 to 2004...
