1、企业背景
某集团经过业务发展，总公司在广州市体育中心附近，在海珠区和白云区有二个分公司，为了实现快捷的信息交流和资源共享，需要构建统一网络，整合公司所有相关业务流程。总公司采用双核心的网络架构模式，采用专线接入互联网，二个分公司分别租用二条专线光纤线路进行连接，特向ISP供应商取得如下公网IP地址：202.16.10.5~20/24，现要求组建网络，总体要求如下：
1、保证整个网络的稳定性、可靠性。
2、各单位部门能通过地址转换连接上互联网。
3、各部门划分VLAN，只有经理室才能访问分公司。
4、要求集团各部门能通过FTP服务器进行文件传输。
5、内网和外网均能访问公司的主页(WEB1 服务器)。
6、只有财务部和经理部的人员才能访问(WEB2 服务器)
