SIP话机的防火墙功能的配置及应用

介绍

防火墙的作用

防火墙功能可以设定防火墙的输入输出规则,利用这些设定可以防止一些恶意的网络存取,或限制内部使用者存取外部网络的一些资源,提高安全性。

防火墙功能配置的详细描述
防火墙通过此页面可以设定是否启用输入,输出防火墙,这个功能支持两种规则: 输入规则和输出规则。每条规则都将分配一个序号,最大允许每种规则各设定10条。
考虑到防火墙设定的复杂性,下面将以一个实例来进行说明:
防火墙类型
防火墙功能配置
字段名称                       说明


开启输入规则                     表示启用输入规则应用。开启输出规则 表示启用输出规则应用。


输入/输出                           为选择当前添加规则是输入还是输出规则; 禁止/允许 为选择当前规则配置是禁止还是允许;


协议类型                            过滤的协议类型,共有四种:TCP,UDP,ICMP,IP。


过滤端口范围                     过滤的端口范围


源地址                              为源地址。源地址可以是主机地址、网络地址,也可以是全部地址0.0.0.0;也可以是类似*.*.*.0的网络地址,如:192.168.1.0。


目的地址                           为目的地址,目的地址可以是具体IP地址,也可以是全部地址0.0.0.0;也可以是类似*.*.*.0的网络地址,如: 192.168.1.0。


源子网掩码                        为源地址掩码,当配置为255.255.255.255时即说明是具体主机,当设置为                                                    255.255.255.0类型的子网掩码时, 说明过滤的是一个网段;


目的子网掩码                    为目的地址掩码,当配置为255.255.255.255时即说明是具体主机,当设置为255.255.255.0类型的子网掩码时,说明过滤的是一个网段;


本话机IP:192.168.1.114
当设定好后点击【新增】,会在防火墙输出规则里新增一项,如下图所示:
新增防火墙配置
然后选择开启输出规则,并点击按钮【提交】。操作步骤及现象:
1. 当话机(192.168.1.114)运行:ping 192.168.1.118,就会因为输出规则的禁止而无法发送数据包到192.168.1.118。


2. 话机(192.168.1.114)运行:ping 192.168.1.0 ~ 192.168.1.255网段的其它IP也无法发出ICMP数据包。


3. 设备(192.168.1.118)运行:ping 192.168.1.114,抓包可以看到(192.168.1.118)发出了ICMP数据包,(192.168.1.114)可以收到数据包,但是因为禁止输出规则导致(192.168.1.114)没有回复。


注:话机ping功能在 lcd的菜单->应用->Ping
删除防火墙设定
选取想要删除的列表编号,点击【删除】即能删除掉选定的列表;
