![]() ![]() Some factory routers images I think from asus has the ability to access the router itself remotely and then ask it to send the data to wake your computers mac address. Once you do that you might as well just use the application that is also available on many of these router images that lets you remotely login to the router and have it send a real wake on lan. There are methods to do stuff like map static ip ARP entries to broadcast mac addresses but I have not see a router running factory firmware that can do that you have to load third party firmware. This is why you people posting that misinformation. So during that amount of time you can think you have "wake on WAN" functional. If the machine was active the router will have a ARP entry cached that maps a IP to the mac but this normally only last maybe 15 minutes. There is no way to forward a mac address because internet is based on IP address not mac addresses.Īlthough people claim to get this to work using port forwarding it only works for a short time. On a router you can only do things like set the main wan ip to a internal lan ip. Ethernet has no concept of IP addresses or ports it only understands mac addresses. The main problem is when a pc is asleep the OS and main cpu are not running. There is no such thing as "wake on WAN" everything you find is a hack that does not work with most consumer routers. The method of port forwarding though the router does not really work. You of course need to leave a machine on and connected to team viewew all the time. Their method of using a slave computer that you remotely access to have it send the wake on lan to a computer that is off will work. You would also need to put in a port forward to this dummy so you can send from the outside.I am surprised team viewer publishes incorrect information., then again it may not be an employee that wrote that. You would need to map a dummy ip to mac address. Otherwise you need to have a router that you can put in a static arp which as far as I know only ones with third party firmware. The best method is a router that you can access remotely and ask it to send a actual WoL packet on your behalf. You probably will need to reboot your router. Enter the TCP and UDP ports that you need to forward for Teamviewer in the corresponding boxes in your router. Put the IP address of your computer in the proper box in your router. Locate your routers port forwarding section. Select on Enable Port Forwarding, and click on Add profile. The way to forward a port is: You can start by logging in to your router. Click on WAN, and choose Virtual Server. When the arp entry times out in the router the router attempt to issue a ARP command to map the IP to the MAC but since the PC is turned off it does not respond to ARP messages so the router never gets a way to remap the ip to the mac.īottom line is you likely can not make this work with your router. Open your browser, type in and go to Advanced Settings. What happens when there is a ARP entry in the router the WoL packet is sent mac of the actual machine rather than the broadcast. ![]() The reason you can get it to work sometimes is many PC accept data they technically should not to wake. Wake on LAN sends a very special packet to the broadcast mac address with the mac of your machine in it. When the machine is shutdown the OS is not running so there are no IP addresses. The MAC address in the static ARP entry isnt even relevant - if its unknown or its node is down its flooded to the entire network anyway. My router can wake any computer that is accessed, so i setup a forwarded port that i block with windows firewall. ) it might be easier to not use teamviewer for WOL. If youre forwarding to a specific (unicast) IP address with a static ARP entry in the router you can minimize the risk. December 2016 What have you done so far Give us some more information (router model, ip-adressing fixed or dynamic, dyndns already setup. The problem is that my router does not allow me to forward anything to the broadcast IP. 1 Any port forwarding is a security risk. What is happening is you attempting to use a IP address instead of a MAC address. Im trying to setup Wake-on-Lan for some of the LAN computers at home and it seems that I need to open a UDP port (7 or 9 being the most common) and forward all requests to the broadcast IP, which in my case is 192.168.1.255. The reason it likely works from home is you did not wait many hours after you shut the machine down to test it. You likely have the standard problem because there is no such thing as wake on WAN. ![]()
