五、访问控制列表
1.放开特权IP地址权限
access-list 100 permit ip host 192.168.0.2 any
access-list 100 permit ip host 192.168.0.3 any
access-list 100 permit ip host 192.168.0.4 any
access-list 100 permit ip host 192.168.0.5 any
access-list 100 permit ip host 192.168.0.6 any
access-list 100 permit ip host 192.168.0.7 any
access-list 100 permit ip host 192.168.0.8 any
2.允许其他用户使用的协议
access-list 100 permit tcp any any eq 135
access-list 100 permit udp any any eq domain
access-list 100 permit icmp any any
3.开放MSN
access-list 100 permit tcp any any eq 1863
access-list 100 permit tcp any any eq 3389
access-list 100 permit tcp any any eq 1503
access-list 100 permit tcp any any eq 6891
access-list 100 permit tcp any any eq 443
4.开放QQ
access-list 100 permit tcp any any range 6891 6900
access-list 100 permit tcp any any range 4000 4010
access-list 100 permit tcp any any range 8000 8010
5.开放MAIL
access-list 100 permit tcp any any eq smtp
access-list 100 permit tcp any any eq pop3
access-list 100 permit tcp any any eq 143
6.开放特定网站
access-list 100 permit tcp any host 60.28.30.73 eq www
access-list 100 permit tcp any host 61.135.150.104 eq www
access-list 100 permit tcp any host 61.135.150.98 eq www
7.开放SKYPE
因为全部用户需要使用SKYPE,而SKYPE软件使用UDP协议,且通信端口并不固定,故全部开放UDP端口。
access-list 100 permit udp any any
access-list 100 permit tcp any host 61.135.159.159 eq www
access-list 100 permit tcp any host 130.117.72.81 eq www
access-list 100 permit tcp any host 198.173.5.35 eq www
access-list 100 permit tcp any host 61.135.159.183 eq www
access-list 100 permit tcp any host 61.135.158.236 eq www
access-list 100 permit tcp any host 58.61.33.32 eq www
因网络需求较多,网络的管理模式较为死板,以后将给网络管理带来很多不变,如新进员工,或者客人到访时,首先需要选择IP地址,调整IP地址与MAC地址对应关系,最后调整DHCP服务。今后可以考虑对员工的桌面进行管理,将网络需求转化为软件需求,减少网络的负责程度。总之,网络需求越少管理越简单,网络需求越多,管理越麻烦。
