华为防火墙USG6000V（防火墙直路部署，上下行连接交换机） _交换机

男儿欲遂平生志，五经勤向窗前读。这篇文章主要讲述华为防火墙USG6000V：防火墙直路部署，上下行连接交换机相关的知识，希望能为你提供帮助。
网络需求
拓扑如下，企业的两台FW的业务接口都工作在三层，上下行分别连接二层交换机。上行交换机连接运营商的接入点，运营商为企业分配的IP地址为1.1.1.1。现在希望两台FW以主备备份方式工作。正常情况下，流量通过FW_A转发。当FW_A出现故障时，流量通过FW_B转发，保证业务不中断。
业务接口工作在三层，上下行连接交换机的主备备份组网

配置步骤
1.完成网络基本配置。

FW1	FW2
# 配置FW各个接口的IP地址。
< FW1> system-view [FW1] interface GigabitEthernet 1/0/1 [FW1-GigabitEthernet1/0/1] ip address 10.2.0.1 24 [FW1-GigabitEthernet1/0/1] quit [FW1] interface GigabitEthernet 1/0/3 [FW1-GigabitEthernet1/0/3] ip address 10.3.0.1 24 [FW1-GigabitEthernet1/0/3] quit [FW1] interface GigabitEthernet 1/0/6 [FW1-GigabitEthernet1/0/6] ip address 10.10.0.1 24 [FW1-GigabitEthernet1/0/6] quit	< FW2> system-view [FW2] interface GigabitEthernet 1/0/1 [FW2-GigabitEthernet1/0/1] ip address 10.2.0.2 24 [FW2-GigabitEthernet1/0/1] quit [FW2] interface GigabitEthernet 1/0/3 [FW2-GigabitEthernet1/0/3] ip address 10.3.0.2 24 [FW2-GigabitEthernet1/0/3] quit [FW2] interface GigabitEthernet 1/0/7 [FW2-GigabitEthernet1/0/6] ip address 10.10.0.2 24 [FW2-GigabitEthernet1/0/6] quit
# 将FW各接口加入相应的安全区域。
[FW1] firewall zone trust [FW1-zone-trust] add interface GigabitEthernet 1/0/3 [FW1-zone-trust] quit [FW1] firewall zone dmz [FW1-zone-dmz] add interface GigabitEthernet 1/0/6 [FW1-zone-dmz] quit [FW1] firewall zone untrust [FW1-zone-untrust] add interface GigabitEthernet 1/0/1 [FW1-zone-untrust] quit	[FW2] firewall zone trust [FW2-zone-trust] add interface GigabitEthernet 1/0/3 [FW2-zone-trust] quit [FW2] firewall zone dmz [FW2-zone-dmz] add interface GigabitEthernet 1/0/6 [FW2-zone-dmz] quit [FW2] firewall zone untrust [FW2-zone-untrust] add interface GigabitEthernet 1/0/1 [FW2-zone-untrust] quit
# 在FW上配置缺省路由，下一跳为1.1.1.10，使内网用户的流量可以正常转发至AR1。
[FW1] ip route-static 0.0.0.0 0.0.0.0 1.1.1.10	[FW2] ip route-static 0.0.0.0 0.0.0.0 1.1.1.10

2.配置VRRP备份组。

FW1	FW2
# 在FW1上行业务接口GE1/0/1上配置VRRP备份组1，并设置其状态为Active。在FW2上行业务接口GE1/0/1上配置VRRP备份组1，并设置其状态为Standby。需要注意的是如果接口的IP地址与VRRP备份组地址不在同一网段，则配置VRRP备份组地址时需要指定掩码。
[FW1] interface GigabitEthernet 1/0/1 [FW1-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 1.1.1.1 24 active [FW1-GigabitEthernet1/0/1] quit	[FW2] interface GigabitEthernet 1/0/1 [FW2-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 1.1.1.1 24 standby [FW2-GigabitEthernet1/0/1] quit
# 在FW1下行业务接口GE1/0/3上配置VRRP备份组2，并设置其状态为Active。在FW2下行业务接口GE1/0/3上配置VRRP备份组2，并设置其状态为Standby。
[FW1] interface GigabitEthernet 1/0/3 [FW1-GigabitEthernet1/0/3] vrrp vrid 2 virtual-ip 10.3.0.3 active [FW1-GigabitEthernet1/0/3] quit	[FW2] interface GigabitEthernet 1/0/3 [FW2-GigabitEthernet1/0/3] vrrp vrid 2 virtual-ip 10.3.0.3 standby [FW2-GigabitEthernet1/0/3] quit

指定心跳口并启用双机热备功能。

FW1	FW2
[FW1] hrp interface GigabitEthernet 1/0/6 remote 10.10.0.2 [FW1] hrp enable	[FW2] hrp interface GigabitEthernet 1/0/6 remote 10.10.0.1 [FW] hrp enable

在FW1上配置安全策略。双机热备状态成功建立后，FW1的安全策略配置会自动备份到FW2上。
# 配置安全策略，允许内网用户访问Internet。

HRP_M[FW1] security-policy
HRP_M[FW1-policy-security] rule name trust_to_untrust
HRP_M[FW1-policy-security-rule-trust_to_untrust] source-zone trust
HRP_M[FW1-policy-security-rule-trust_to_untrust] destination-zone untrust
HRP_M[FW1-policy-security-rule-trust_to_untrust] source-address 10.3.0.0 24
HRP_M[FW1-policy-security-rule-trust_to_untrust] action permit
HRP_M[FW1-policy-security-rule-trust_to_untrust] quit
HRP_M[FW1-policy-security] quit

在FW1上配置NAT策略。双机热备状态成功建立后，FW1的NAT策略配置会自动备份到FW2上。
# 配置NAT策略，当内网用户访问Internet时，将源地址由10.3.0.0/16网段转换为地址池中的地址（1.1.1.2-1.1.1.5）。

HRP_M[FW1] nat address-group group1
HRP_M[FW1-address-group-group1] section 0 1.1.1.2 1.1.1.5
HRP_M[FW1-address-group-group1] quit
HRP_M[FW1] nat-policy
HRP_M[FW1-policy-nat] rule name policy_nat1
HRP_M[FW1-policy-nat-rule-policy_nat1] source-zone trust
HRP_M[FW1-policy-nat-rule-policy_nat1] destination-zone untrust
HRP_M[FW1-policy-nat-rule-policy_nat1] source-address 10.3.0.0 16
HRP_M[FW1-policy-nat-rule-policy_nat1] action source-nat address-group group1

配置Switch和内网PC。

分别将两台Switch的三个接口加入同一个VLAN，具体配置命令请参考交换机的相关文档。
将内网PC的默认网关设置为VRRP备份组2的虚拟IP地址，具体步骤略。

配置AR1
# 在AR1上配置到FW的等价路由，路由下一跳指向VRRP备份组1的虚拟IP地址。

结果验证

在FW1和FW2上执行display vrrp命令，检查VRRP组内接口的状态信息，显示以下信息表示VRRP组建立成功。

在FW1和FW2上执行display hrp state verbose命令，检查当前VGMP组的状态，显示以下信息表示双机热备建立成功。

AR1位于Untrust区域。在Trust区域的PC端能够ping通Untrust区域的AR1。分别在FW1和FW2上检查会话。
