近段時(shí)間生產(chǎn)平臺(tái)服務(wù)上看到不少IP地址發(fā)起大量線程，本來打算利用APF或者腳本來阻止這些連接。但想想為何在最后的防御上面做啦？這里我使用防火墻的訪問控制列表拒絕就行了，考慮控制列表經(jīng)常維護(hù)操作平凡建議創(chuàng)建組。貼上我的實(shí)例：

object-group network deny_ddos

host 70.39.96.146

object-group network permit_other

any

ip access-list extended deny_ddos

deny   ip object-group deny_ddos any

permit ip object-group permit_other any

interface FastEthernet0/0/0

description Out-Web80-1 (CNportal)

ip address 115.85.150.130 255.255.255.248

ip access-group deny_ddos in

no ip redirects

no ip unreachables

no ip proxy-arp

ip nat outside

ip virtual-reassembly in

duplex auto

speed auto
