3 配置步骤

3.1  SWA配置

3.1.1  配置交换机下联防火墙接口

交换机配置vlan 10将下联防火墙的15和16接口加入vlan10，并创建vlan10接口IP地址为1.1.1.1

system

[H3C]vlan10

[H3C-vlan10]port GigabitEthernet 1/0/15 GigabitEthernet 1/0/16

[H3C]interface Vlan-interface 10

[H3C-Vlan-interface10]ip address 1.1.1.1 24

配置到内网网段的回程路由，下一跳为防火墙Reth1接口地址。

[H3C]ip route-static 2.2.2.0 24 1.1.1.2

注：实际组网中应该将内网网段全部添加进回程路由。

3.2  SWB配置

3.2.1  配置交换机上联防火墙接口

交换机配置vlan 20将下联防火墙的14和15接口加入vlan20，并创建vlan20接口IP地址为2.2.2.1。

system

[H3C]vlan20

[H3C-vlan20]port GigabitEthernet 1/0/14 GigabitEthernet 1/0/15

[H3C]interface Vlan-interface 20

[H3C-Vlan-interface20]ip address 2.2.2.1 24

配置默认路由到防火墙Reth2接口地址。

[H3C]ip route-static 0.0.0.0 0 2.2.2.2

3.3  防火墙配置

3.3.1  FWA与FWB建立堆叠

具体配置可参考防火墙虚拟化配置举例，本章不做介绍。

3.3.2  配置冗余接口关联上下行物理端口

1. 创建Reth1接口

创建Reth1接口配置IP地址为1.1.1.2/24，并配置1/0/15成员优先级为255，2/0/15成员优先级为50。

system-view

[H3C] interface reth 1

[H3C-Reth1] ip address 1.1.1.2 24

[H3C-Reth1] member interface gigabitethernet 1/0/15 priority 255

[H3C-Reth1] member interface gigabitethernet 2/0/15 priority 50

[H3C-Reth1] quit

2. 创建Reth2接口

创建Reth2接口配置IP地址为2.2.2.2/24，并配置1/0/14成员优先级为255，2/0/14成员优先级为50。

system-view

[H3C] interface reth 1

[H3C-Reth1] ip address 2.2.2.2 24

[H3C-Reth1] member interface gigabitethernet 1/0/14 priority 255

[H3C-Reth1] member interface gigabitethernet 2/0/14 priority 50

[H3C-Reth1] quit

3.3.3  配置冗余接口关联上下行物理端口

配置track检测上下行端口的物理状态

[H3C] track 1 interface gigabitethernet 1/0/15 physical

[H3C-track-1] quit

[H3C] track 2 interface gigabitethernet 1/0/14 physical

[H3C-track-2] quit

[H3C] track 3 interface gigabitethernet 2/0/15 physical

[H3C-track-3] quit

[H3C] track 4 interface gigabitethernet 2/0/14 physical

[H3C-track-4] quit

3.3.4  配置冗余组关联冗余接口

1. 创建节点1与防火墙A所有接口绑定

[H3C] redundancy group aaa

[H3C-redundancy-group-aaa] node 1

[H3C-redundancy-group-aaa-node1] bind slot 1

[H3C-redundancy-group-aaa-node1] priority 100

[H3C-redundancy-group-aaa-node1] track 1 interface gigabitethernet 1/0/15

[H3C-redundancy-group-aaa-node1] track 2 interface gigabitethernet 1/0/14

[H3C-redundancy-group-aaa-node1] quit

2. 创建节点2与防火墙B所有接口绑定

[H3C-redundancy-group-aaa] node 2

[H3C-redundancy-group-aaa-node2] bind slot 2

[H3C-redundancy-group-aaa-node2] priority 50

[H3C-redundancy-group-aaa-node2] track 3 interface gigabitethernet 1/0/15

[H3C-redundancy-group-aaa-node2] track 4 interface gigabitethernet 1/0/14

[H3C-redundancy-group-aaa-node2] quit

3.3.5  将冗余接口加入冗余组

[H3C-redundancy-group-aaa] member interface reth 1

[H3C-redundancy-group-aaa] member interface reth 2

[H3C-redundancy-group-aaa] quit

3.3.6  开启会话热备

[H3C] session synchronization enable

3.3.7  安全策略配置

1. 将Reth1加入安全域

将Reth加入Untrust区域

[H3C]security-zone name Untrust

[H3C-security-zone-Untrust]import interface Reth1

将Reth2加入trust区域

[H3C]security-zone name trust

[H3C-security-zone-trust]import interface Reth2

[H3C-security-zone-trust]quit

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。

2. 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

#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 local

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

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

[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

[H3C]zone-pair security source Untrust destination local

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

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

[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

[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

3. 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

4 检验配置结果

4.1.1  正常时查看冗余组状态

查看冗余组状态，可以看到节点1为主节点。

显示Reth信息。可以看到Reth1和Reth2中优先级高的成员接口处于激活状态。

4.1.2  当FWA宕机后时查看冗余组状态

查看冗余组状态，可以看到节点2为主节点。（将1/0/14接口关闭）

显示Reth信息。节点2成员接口处于激活状态。

重新打开1/0/14接口后，冗余组主动切回。
