网络配置综合实验(3)

interface Ethernet0/1 no shutdown

switchport access vlan 20 end

write memory 配置NAT转换 config terminal

nat (inside) 1 0.0.0.0 0.0.0.0

global (outside) 1 10.4.110.31-10.4.110.40 netmask 255.255.255.0 end

write memory 配置路由 config terminal

route outside 0.0.0.0 0.0.0.0 10.4.110.1 1 route inside 172.16.2.0 255.255.255.0 12.1.1.2 1 route inside 23.1.1.0 255.255.255.0 12.1.1.2 1 end

write memory

三、服务器配置

1、 FTP服务器

ftp服务器环境：window 7 工具：serv-u

ftp服务器地址： IP:172.16.2.252

子网掩码：255.255.255.224 默认网关：172.16.2.254 IP访问规则：

即只有采购部网段172.16.2.128-172.16.2.158才能访问FTP服务器，进行共享文件，其他部门不能登录

2、 DNS服务器

Dns服务器系统环境：linux5

Dns服务器地址：

服务器所需软件包：

[root@sevice1 ~]# rpm -qa|grep bind bind-chroot-9.3.4-6.P1.el5 bind-libs-9.3.4-6.P1.el5 bind-9.3.4-6.P1.el5 ypbind-1.19-8.el5 bind-utils-9.3.4-6.P1.el5

caching-nameserver-9.3.4-6.P1.el5 基本配置文件 对主配置文件的配置 /etc/named.conf // named.rfc1912.zones: //

// Provided by Red Hat caching-nameserver package //

// ISC BIND named zone configuration for zones recommended by // RFC 1912 section 4.1 : localhost TLDs and address zones //

// See /usr/share/doc/bind*/sample/ for example named configuration files. // options {

directory \};

zone \ type hint; file \};

zone \ type master;

file \ allow-update { none; }; };

zone \ type master; file \ allow-update { none; }; };

zone \ type master; file \ allow-update { none; }; };

zone \ type master;

file \ allow-update { none; }; };

zone \

type master;

file \ allow-update { none; }; };

zone \ type master; file \ allow-update { none; }; };

zone \

/bin/bash: indent: command not found file \ allow-update { none; }; };

zone \ //自己添加的正向区域 type master;

file \ //正向区域文件名 allow-update { none; }; };

zone \ //自己添加的反向区域 type master;

file \ //正向区域文件名 allow-update { none; }; }

生成正向区域文件和方向区域文件： /var/named/chroot/var/named/2.16.172.zone
