The IP's '10.10.1.255' are the broadcast addresses of the VLAN's you want to send WoL packets too the above example will mean that the suitable WoL packets for the MAC address you are interested in will be sent to the subnets '10.10.1.0/24'. If you prefer Mac computers - then you can use osx safe mode Once installed just edit '/var/www/html/fog/wol/wol.php' to match something like: It has no concept of support for cross-subnet WoL and shockingly you need to use sudo to create a UDP packet that can be created by a regular user using root pointlessly (a webserver should never run a command directly as root).Īs most of your are Deadrat weenies (Debian users just type 'aptitude install wakeonlan') so you should from download the wakeonlan tool (the file) and install it running as root: ![]() If you want to be able to send WoL packets from other machines on your network then obviously add additional whitelisted of IP's to the access-list.Īlas we have not finished yet, we need to fix some serious problems in FOG servers methology when doing WoL. You create a standard access-list (numbered '50' in our example):Īccess-list 50 remark directed broadcast permits (ie WoL)Īnd for all the VLAN's you want to use WoL on you slip into the configuration: To actually forward the WoL packets to VLAN's without opening yourself up to being the source of a Smurf Attack's you need to use 'ip directed-broadcast' with care. these affect only broadcast traffic on these UDP ports, not the functionality of, for example, unicast TFTP traffic on your network Now you want to turn off broadcast forwarding for all of the other services, you would have to be crazy to want them to spill over, with: To disable the forwarding of broadcast packets to specific addresses, use the no form of this command. To have the Cisco IOS software forward User Datagram Protocol (UDP) broadcasts, including BOOTP, received on an interface, use the ip helper-address interface configuration command. If an IP helper address is specified and UDP forwarding is enabled, broadcast packets destined to the following port numbers are forwarded by default. We shall assume you wimped out configuring your own DHCP server (if you do not know about 'ip helper-address') and your FOG server is the center of life on your network. 5 The Simple One Modification Method: Modify wol.php. ![]()
