防火墙概览系列又更新了! 本文会简单介绍下 huawei usg6000 的防火墙。

提示

输入 ‘?’ 号 可以命令提示,tab 补全命令,quit 或者 ctrl + z 可以退回上个层级

进入配置 configure 模式

system-view

huawei usg Configuring NAT

Static NAT (1 对 1)

使用 static nat 来进行目的地址转换

设备:cisco asa 192.168.1.204

华为墙做 nat 墙

命令:

security-policy
rule name untrust_2_dmz_c0dbd
description create by NAP 97e5819c-2c2c-435b-9e29-5e40d8715f9a
source-zone untrust
destination-zone dmz
source-address address-set WS_172.16.205.1_32
destination-address address-set ws_10.1.206.1
service Any
action permit
nat server untrust_2_dmz_b9fe1 global 12.1.214.33 inside 10.1.206.1

cisco 设备上设置路由:

在 cisco 上 ping 12.1.214.33

转换结果

Source NAT

源 NAT 策略用于实现内网主机使用私网地址访问 Internet。系统会将内网主机报文的源 IP 由私网地址转换为公网地址。在配置时,转换前的源地址应选择私网地址或地址组(可多选),转换后的源地址可以使用 NAT 地址池或使用报文出接口的公网 IP 地址。

nat-policy
[USG6000V2-policy-nat]
rule name snat1
[USG6000V2-policy-nat-rule-snat1]
description test
[USG6000V2-policy-nat-rule-snat1]
destination-zone untrust
[USG6000V2-policy-nat-rule-snat1]
source-zone trust
[USG6000V2-policy-nat-rule-snat1]
source-address address-set WS_192.168.1.11_32
[USG6000V2-policy-nat-rule-snat1]
destination-address address-set WS_2.3.1.120_32
[USG6000V2-policy-nat-rule-snat1]
service TCP_241
[USG6000V2-policy-nat-rule-snat1]
action nat address-group test2            //test2为地址池里面的地址
[USG6000V2-policy-nat-rule-snat1]
Destination NAT

image.png

将公网 ip12.1.214.33 的 443 端口 映射到私有 ip 10.1.206.1 的 999

nat server untrust_2_dmz_b9fe1 protocol tcp  global 12.1.214.33 443 inside 10.1.206.1 9999

所以我们会通过 nat-server 的方式来进行 dnat 的配置
