华为设备acl配置
拓扑图：
需求：
1、-vlan10内所有的主机,只能通过http访问vlan30-server的服务器;不能访问vlan40-server服务器
2、-vlan20-pc1主机,可以访问vlan40-server服务器,不能访问vlan30-server服务器
3、-vlan30-pc1主机,不能访问vlan20-server服务器,可以访问vlan40-server服务器
4、-PublicServer服务器对vlan10和vlan20 仅仅提供ftp服务
5、-PublicServer服务器对vlan30-server和vlan40-server仅仅提供http服务
6、-PublicServer服务器对所有pc提供dns服务
7、-所有节点和主机均能够ping通

分析规则:
1、-vlan10内所有的主机,只能通过http访问vlan30-server的服务器;不能访问vlan40-server服务器
192.168.10.0 0.0.0.255 网段要带掩码, 192.168.30.200 0 ip 掩码可简写为 0
rule permit tcp source 192.168.10.0 0.0.0.255 destination 192.168.30.200 0 destination-port eq 80
rule deny ip source 192.168.10.0 0.0.0.255 destination 192.168.40.200 0.0.0.0
返回规则
rule permit ip source 192.168.30.200 0 destination 192.168.10.0 0.0.0.255
2、-vlan20-pc1主机,可以访问vlan40-server服务器,不能访问vlan30-server服务器
rule permit ip source 192.168.20.100 0 destination 192.168.40.200 0
rule deny ip source 192.168.20.100 0 destination 192.168.30.200 0
返回规则
rule permit ip source 192.168.40.200 0 destination 192.168.20.100 0
3、-vlan30-pc1主机,不能访问vlan20-server服务器,可以访问vlan40-server服务器
rule deny ip source 192.168.30.100 0 destination 192.168.20.200 0
vlan30 和vlan40 不跨路由器规则 无需设置规则
返回规则
无
4、-PublicServer服务器对vlan10和vlan20 仅仅提供ftp服务
rule permit tcp source 192.168.10.0 0.0.0.255 destination 192.168.100.200 0 destination-port eq 21
rule permit tcp source 192.168.20.0 0.0.0.255 destination 192.168.100.200 0 destination-port eq 21
返回规则
rule permit ip source 192.168.100.200 0 destination 192.168.10.0 0.0.0.255
rule permit ip source 192.168.100.200 0 destination 192.168.20.0 0.0.0.255
5、-PublicServer服务器对vlan30和vlan40-server仅仅提供http服务
rule permit tcp source 192.168.30.0 0.0.0.255 destination 192.168.100.200 0 destination-port eq 80
rule permit tcp source 192.168.40.200 0 destination 192.168.100.200 0 destination-port eq 80

rule permit ip source 192.168.100.200 0 destination 192.168.40.0 0.0.0.255
6、-PublicServer服务器对所有pc提供dns服务
rule permit udp source any destination 192.168.100.200 0 destination-port eq 53
返回规则
rule permit ip source 192.168.100.200 0 destination any
7、-所有节点和主机均能够ping通
rule permit icmp source any destination any
以上规则在三个路由接口的outbound(出站)总结为:
int g0/0/1: acl3000
即是:vlan10,vlan20及PublicServer服务器,在int g0/0/1的outbound规则
rule permit tcp source 192.168.10.0 0.0.0.255 destination 192.168.30.200 0 destination-port eq 80
rule permit ip source 192.168.20.100 0 destination 192.168.40.200 0
rule deny ip source 192.168.10.0 0.0.0.255 destination 192.168.40.200 0.0.0.0
rule deny ip source 192.168.20.100 0 destination 192.168.30.200 0
rule permit icmp source any destination any
rule deny ip source any destination any
int g0/0/0: acl3001
即是:vlan30,vlan40及PublicServer服务器,在int g0/0/0的outbound规则
rule permit ip source 192.168.30.200 0 destination 192.168.10.0 0.0.0.255

rule permit ip source 192.168.100.200 0 destination any
rule permit icmp source any destination any
rule deny ip source any destination any
int g0/0/2 acl3002
即是:vlan10,vlan20,vlan30,vlan40,在int g0/0/2的outbound规则
rule permit tcp source 192.168.10.0 0.0.0.255 destination 192.168.100.200 0 destination-port eq 21
rule permit tcp source 192.168.20.0 0.0.0.255 destination 192.168.100.200 0 destination-port eq 21
rule permit tcp source 192.168.30.0 0.0.0.255 destination 192.168.100.200 0 destination-port eq 80
rule permit tcp source 192.168.40.200 0 destination 192.168.100.200 0 destination-port eq 80
rule permit udp source any destination 192.168.100.200 0 destination-port eq 53
rule permit icmp source any destination any
rule deny ip source any destination any

测试:
1、-vlan10内所有的主机,只能通过http访问vlan30-server的服务器;不能访问vlan40-server服务器
vlan10 只能通过http访问vlan30-server服务器
vlan10 访问vlan30-server的http正常
6、-PublicServer服务器对所有pc提供dns服务
当pc通过域名解析访问服务器时,必须满足其它规则里也不冲突.
1、-vlan10内所有的主机,只能通过http访问vlan30-server的服务器;不能访问vlan40-server服务器
