1 配置需求或说明

1.1  适用的产品系列

本案例适用于软件平台为Comware V7系列防火墙：F100-X-G2、F1000-X-G2、F100-WiNet、F1000-AK、F10X0等

注：本案例是在F100-C-G2的Version 7.1.064, Release 9510P08版本上进行配置和验证的。

1.2  配置需求

如下组网图所示，在原有的网络中增加防火墙来提高网络安全性，但又不想对原有网络配置进行改动，所以需要防火墙采用透明模式部署；其中GigabitEthernet 1/0/1接口接原有路由器的下联口，GigabitEthernet 1/0/3接口接原有的交换机上联口。

3 配置步骤

3.1配置连接路由器接口

#把1/0/1端口设置成二层模式

<H3C>system-view

[H3C]interface GigabitEthernet 1/0/1

[H3C-GigabitEthernet1/0/1]port link-mode bridge

[H3C-GigabitEthernet1/0/1]quit

#将1/0/1端口加入到Untrust域

[H3C]security-zone name Untrust

[H3C-security-zone-Untrust]import interface GigabitEthernet1/0/1 vlan 1 to 4094

[H3C-security-zone-Untrust]quit

3.2配置连接核心交换机接口

#把1/0/3端口设置成二层模式

[H3C]interface GigabitEthernet 1/0/3

[H3C-GigabitEthernet1/0/3]port link-mode bridge

[H3C-GigabitEthernet1/0/3]quit

#将1/0/3端口加入到Trust域

[H3C]security-zone name Trust

[H3C-security-zone-Trust]import interface GigabitEthernet1/0/3 vlan 1 to 4094

[H3C-security-zone-Trust]quit

3.1  安全策略配置

防火墙目前版本存在两套安全策略，请在放通安全策略前确认设备运行那种类型的安全策略？以下配置任选其一。

1. 通过命令“display cu | in security-policy”如果查到命令行存在“security-policy disable”或者没有查到任何信息，则使用下面策略配置。

[H3C]display cu | in security-policy

 security-policy disable

配置安全策略将Trust到Untrust域内网数据放通

#创建对象策略pass。

[H3C]object-policy ip pass

[H3C-object-policy-ip-pass] rule 0 pass

[H3C-object-policy-ip-pass]quit

创建Trust到Untrust域的域间策略调用pass策略。

[H3C]zone-pair security source Trust destination Untrust

[H3C-zone-pair-security-Trust-Untrust]object-policy apply ip pass

[H3C-zone-pair-security-Trust-Untrust]quit

配置安全策略将Trust到Local域、Local到Trust、Local到Untrust域数据全放通策略

#创建Trust到Local域的域间策略调用pass策略。

[H3C]zone-pair security source Trust destination Local

[H3C-zone-pair-security-Trust-Local]object-policy apply ip pass

[H3C-zone-pair-security-Trust-Local]quit

#创建Local到Trust域的域间策略调用pass策略。

[H3C]zone-pair security source Local destination Trust

[H3C-zone-pair-security-Local-Trust]object-policy apply ip pass

[H3C-zone-pair-security-Local-Trust]quit

#创建Local到Untrust域的域间策略调用pass策略。

[H3C]zone-pair security source Local destination Untrust

[H3C-zone-pair-security-Local-Untrust]object-policy apply ip pass

[H3C-zone-pair-security-Local-Untrust]quit

2. 通过命令“display cu | in security-policy”如果查到命令行存在“security-policy ip”并且没有查到“security-policy disable”，则使用下面策略配置。

[H3C]display cu | in security-policy

security-policy ip

创建安全策略并放通local到trust和trust到local的安全策略。

[H3C]security-policy ip

[H3C-security-policy-ip]rule 10 name test

[H3C-security-policy-ip-10-test]action pass

[H3C-security-policy-ip-10-test]source-zone local

[H3C-security-policy-ip-10-test]source-zone Trust

[H3C-security-policy-ip-10-test]source-zone Untrust

[H3C-security-policy-ip-10-test]destination-zone local

[H3C-security-policy-ip-10-test]destination-zone Trust

[H3C-security-policy-ip-10-test]destination-zone Untrust

[H3C-security-policy-ip-10-test]quit

3.4保存配置

<H3C>save force

3.5查看与验证

配置完成后终端可以上网，路由器和交换机不需要更改配置
