问题描述：
请教，我单位准备用内网的硬盘录像机挂载联通的5G摄像头，我公司内网和联通边界设备为H3C F100-C-G2防火墙。要求：在防火墙上做一对一地址转换，将外部联通网摄像头地址转换为我单位内网的IP地址，使用硬盘录像机管理摄像头。请教各位大神，如何配置。最好是具体配置，谢谢！路由为联通公司工程师用联通公司自带的华为AR2220做的路由，想换为我公司的防火墙。谢谢各位大神！

最佳答案
内网用户通过NAT地址访问外网配置举例（静态地址转换）
1. 组网需求
内部网络用户10.110.10.8/24使用外网地址202.38.1.100访问Internet中的地址为201.20.1.1/24的 Server。
2. 组网图
图2-3 内网用户通过NAT地址访问外网配置组网图（静态地址转换）
3. 配置步骤
(1) 配置接口IP地址
# 根据组网图中规划的信息，配置各接口的IP地址，具体配置步骤如下。
<Device> system-view
[Device] interface gigabitethernet 1/0/1
[Device-GigabitEthernet1/0/1] ip address 10.110.10.1 24
[Device-GigabitEthernet1/0/1] quit
请参考以上步骤配置其他接口的IP地址，具体配置步骤略。
(2) 将接口加入安全域
# 请根据组网图中规划的信息，将接口加入对应的安全域，具体配置步骤如下。
[Device] security-zone name trust
[Device-security-zone-Trust] import interface gigabitethernet 1/0/1
[Device-security-zone-Trust] quit
[Device] security-zone name untrust
[Device-security-zone-Untrust] import interface gigabitethernet 1/0/2
[Device-security-zone-Untrust] quit
(3) 配置静态路由
本举例仅以静态路由方式配置路由信息。实际组网中，请根据具体情况选择相应的路由配置方式。
# 请根据组网图中规划的信息，配置静态路由，本举例假设到达Server所在网络的下一跳IP地址为202.38.1.2，实际使用中请以具体组网情况为准，具体配置步骤如下。
[Device] ip route-static 201.20.1.0 24 202.38.1.2
(4) 配置安全策略
# 配置名称为trust-untrust的安全策略，保证Trust安全域内的Host可以访问Untrust安全域中的Server，具体配置步骤如下。
[Device] security-policy ip
[Device-security-policy-ip] rule name trust-untrust
[Device-security-policy-ip-1-trust-untrust] source-zone trust
[Device-security-policy-ip-1-trust-untrust] destination-zone untrust
[Device-security-policy-ip-1-trust-untrust] source-ip-host 10.110.10.8
[Device-security-policy-ip-1-trust-untrust] destination-ip-host 201.20.1.1
[Device-security-policy-ip-1-trust-untrust] action pass
[Device-security-policy-ip-1-trust-untrust] quit
[Device-security-policy-ip] quit
(5) 配置NAT功能
# 配置内网IP地址10.110.10.8到外网地址202.38.1.100之间的一对一静态地址转换映射。
[Device] nat static outbound 10.110.10.8 202.38.1.100
[Device] interface gigabitethernet 1/0/2
[Device-GigabitEthernet1/0/2] nat static enable
[Device-GigabitEthernet1/0/2] quit
4. 验证配置
# 以上配置完成后，内网主机可以访问外网服务器。通过查看如下显示信息，可以验证以上配置成功。
[Device] display nat static
Static NAT mappings:
Totally 1 outbound static NAT mappings.
IP-to-IP:
Local IP : 10.110.10.8

# 通过以下显示命令，可以看到Host访问某外网服务器时生成NAT会话信息。

您好，请知：
以下是NAT server映射的配置案例，请参考：
组网说明：
本案例采用H3C HCL模拟器的F1060来模拟NAT server典型组网配置，内网和外网在网络拓扑图中已经有了明确的标识，FW1作为内网的出口设备，不仅保护内网的安全，也提供地址转换的服务。内网申请了202.1.100.2-202.1.100.3这两个公网地址，其中202.1.100.2用于FW1与外网互联使用。202.1.100.3用于给内网的WEB服务器转换并对外网提供WEB服务。由于模拟器及物理机的局限性，因此采用H3C HCL模拟器的S5820交换机开启WEB功能模拟成WEB服务器。
配置步骤
1、按照网络拓扑图正确配置IP地址
2、Web_server开启WEB功能，并创建相应账户及赋予权限
3、FW1配置NAT地址转换，并配置默认路由指向外网
4、FW1配置nat server，并发布内网的WEB服务器
配置关键点

请教，针对GRE这种怎么做NAT呢？
GRE的话 网络可达就行了呀 目的不就是摄像头通录像机吗
