How to configure an IP access list to control directed broadcasts for the Cisco Wake-on-LAN setup

Cisco Wake-on-LAN Setup

How to configure an IP access list to control directed broadcasts for the Wake-on-LAN setup.

In order to configure an IP access list to control directed broadcasts, complete one of these steps:

Step 1:

Configure the ip directed-broadcast command directly on an interface:

Hostname(config)#interface FastEthernet
Hostname(config-if)#ip directed-broadcast


Step 2:

Configure an access control list (ACL) in order to permit traffic only from a trusted source.

For example, 192.168.10.10 is the Wake-on-LAN (WoL) server.

Hostname(config)#access-list 10 permit 192.168.10.10


Then, apply that under the VLAN interface:

Hostname(config)#interface Vlan
Hostname(config-if)#ip address x.x.y.y subnet mask
Hostname(config-if)#no ip redirects
Hostname(config-if)#ip directed-broadcast 10
!--- 10 is the ACL number.
