Please log in for more thread options (http://www.corega-international.com/4/54/273/chprd.html). I have been trying to wake up my PC from a remote location sending a WOL magic packet over the Internet. In my router I have added the following firewall service: Name: WOL Type: UDP Start port: 5850 Finish port: 5850 Then I have added the following incoming firewall rule: Service: I have selected the service I have previously created Action: allow always Comment: Wake On Lan Send to LAN Server: I have selected my PC (it is the only one connected to the router) WAN users: Any Log: Always When I send a Wake On Lan magic packet over the Internet with the Depicus tool (http://www.depicus.com/wake-on-lan/wake-on-lan-gui.aspx) I am able to wake up my PC :-) But this works only within a certain amount of time that my PC has been switched off :-( After a while it does NOT work anymore. How is that and how can I fix it? thanks for your support Lucia Italy | ||||||||||||||||||||||||||||

Does your PC have a fixed IP address or does it haved a dynamic (DHCP) address? DHCP addresses have a limited lifetime (lease time). -- Ian Shef 805/F6 * These are my personal opinions Raytheon Company * and not those of my employer.

Please log in for more thread options Generally, WOL is not considered to work on anything other than the same
local subnet. That it can be done via a firewall UDP port is admirable but not expected. Not to mention a bit of a security risk. If it's failing after some interval that might be due to the router clearing it's cache of known arp destinations. I don't know of too many routers that have the ability to retain arp mappings, let alone be programmed with them ahead of time. There may not be a way to resolve this. But you'd have to check with the router maker to be sure. > I have a PC connected to the Internet via a Corega router

Add a static ARP entry to the router for the PC. You might also want to make the IP address of the PC static if it isn't already, though hopefully if the router allows the firewall entry to point to the PC it understands as much.
