(For that matter, many home routers don't even have the function to edit routes.) ![]() It's not something that a typical user would need to do practically the only uses it sees are either WoL via port-forwarding or a poor attempt at "securing" the network. Many home routers indeed don't have this function (or at least not in the web UI). I am not at home for the next 3 weeks and I don't recall my router having the possibility to edit the ARP table (I might be mistaken tho) Yes, if you're trying to use port-forwarding for WoL, that's correct. The second part of my question is: I read here that I am supposed to edit the ARP table of the router to have a static mapping between my pc MAC address and IP so that it doesn't get flushed out. However, the general consensus is that this is a HIGHLY NON RECOMMENDED practice. If your router has an option to send WoL packets to machines in LAN, enable remote management of your router via HTTPS so you can access the router's web gui via browser. Use a low-power raspberry pi to be on 24/7, direct the wol packet to it via ssh and broadcast it via LAN, as explained here. If you can't edit the ARP table, there are two more options: Even then, you might be facing a castrated system allowing a very small subset of commands, like in my case. Editing the ARP table is also not necessarily straightforward: seemingly most routers don't have that option in their web gui, and therefore you have to SSH into them. Having a static DHCP reservation doesn't work because they carry out different functions, as explained here. ![]() One can either:Īdd a static binding to the ARP table. If your router doesn't allow directed broadcasting (apparently most of them), sending a wake on WAN packet to a machine becomes a tad more complicated. So, is there a way I can SSH remotely to the router?Įdit - for those that will stumble in the same issue: I am not at home for the next 3 weeks and I don't recall my router having the possibility to edit the ARP table (I might be mistaken tho). So my question is, is there a way I can circumvent this problem, and be able to turn on my pc remotely even after a it's been in shutdown for a while? I thought step 3 would fix the ARP table flushing, but apparently it didn't (I thought DHCP configs and ARP table were the same thing?). I tested it on 4G and it properly delivers the packet.Īs I said above, everything works fine until remote PC stays turned off for a while. Lastly, I have downloaded an app on my phone ( this one) that sends a magic packet with my remote PC MAC address.Then, in the DHCP config, I mapped my remote PC MAC address to its own IP.Since the router doesn't allow broadcasting, I cannot bind the port to 192.168.1.255 (it says "invalid ip"), and hence I bound it to the IP address of my remote machine. I forwarded port 7 on my router listening to UDP packets.Setup a DDNS service, allowed WoL in BIOS, allowed NIC to WoL on magic packets, disabled fast startup on windows 10 etc.I understood that this is due to the ARP table flushing, and I thought I had addressed this problem by mapping my remote PC IP address to its own MAC address in the DHCP config of its router. I have followed several guides to enable it and it seemed to be working, at first, except that after my remote PC has been turned off for a while, it doesn't work anymore. I setup a system where I can turn on my home computer remotely using Wake on LAN / WAN. My knowledge of networks didn't go beyond what an IP address is until 3 days ago, and a lot of this is still very alien to me. Recap of the possible solutions at the bottom -įirst of all I apologize if I write something that makes no sense.
