Access control lists, their function, and proper implementation are covered in Cisco exams, but the concepts and deployment strategies are also covered in certifications like Security + and CISSP. In this articl
Solved: Hello, I am trying to create ACL on Cisco router which will allow all traffic from inside to internet and only allow specific traffic from internet to inside. This is what I've configured and puted on Router's interface connected to ISP: 10
Inbound Access Lists is applied on the In traffic, when the router receives a packet on its interface the Cisco IOS checks the criteria statements of the ACL for a match, if the packet is permitted the software continuous to process the packet, if the packet is denied the Cisco IOS discar...

On most Cisco devices, a packet with IP options is not switched in hardware, but requires control plane software processing (primarily because there is a need to process the options and rewrite the IP header), so all IP packets wi...
In Cisco IOS® Software Release 12.3(7)JA, the ACL number can be any number from 1 to 99. Standard ACLs can also use the extended range of 1300 to 1999. These additional numbers are expanded IP ACLs. When a standard ACL is configured to deny access to a client, the client still as...

网络中常说的 ACL 是 CISCO IOS 所提供的一种访问控制技术,初期仅 在路由器上支持,近些年来已经扩展到三层交换机,部分最新的二层交换机如 2950 之 类也开始开始提供 ACL 的支持。只不过支持的特性不是那么完善而已。在其他厂商的路 由器或多层交换机上也提供类似的技术,不过名称和配置方法都可能有细微的差别。
The basic syntax used to create a standard numbered access control list on a Cisco router is as follows: Router (config)# access-list (1300-1999) (permit | deny) source-addr (source-wildcard) The various parts mean the following:
