What I do is using OliveTin behind a reverse proxy (traefik with auth) on a Pi. I then have a button in olivetin that sends WoL commands through local network to turn in my ‘big’ server. You can probably run it without issues on a Pi0.

Alternatively, if you have a VPN to your home network, is using an app on your phone to send WoL commands when connected to the VPN. I have tested with both ‘Magic Packet’ and ‘Net Status’ on iOS through WireGuard.

A lot of people are saying WOL doesn't work over the internet, but I've got it working.

Basically port forward UDP 9 to your broadcast address (the last possible IP in your subnet), eg. 192.168.1.255. Then send the WOL to your public IP which will then get broadcasted out over your network by your router.

Typing this out, I realised this seems like a horrible security practice, so I'll probably disable it soon anyway, now that I've got multiple servers and a failover VPN.

I suggest to read up on the way Wake On Lan works, it's pretty neat. it has to send a packet to a local broadcast address. I don't think that can route over the internet so you need some device to send the packet from on the network or over a VPN connection.

For the KVM part, that model server should have some form of remote control. I think they called it the Integrated Management Module (IMM) on those things. The IMM is running as long as the server has power, it's a tiny independent system. They have various licenses/feature sets but at minimum it should get you a web interface to see status of the server as well as power it on & off. It may also have remote console and media options but those are add-on costs so not everybody buys them. The default login information should be somewhere on the chassis unless it was removed or got lost. The old defaults used to be username all uppercase 'USERID' with password exactly 'PASSW0RD' with a zero instead of the letter O. I don't recall when they changed to newer methods but it's worth a try.

Do the lights on the network card light up when it's connected but off? I believe you should have blinking lights if the card is on. Might be some kind of power setting in the bios to keep the network card on/off?

I have had hit and miss WoL on some of my machines, one work around is to use a smart plug of some kind to turn the power on/off, and there should be a setting to boot the PC when the power reconnects? May not directly help you, but might also be easier?

In my experience, you don't, because it never works.

But the server should have an IPMI that allows power control.

Considering it's an IBM wol will likely only work on the lan1 port or the imm port.

However, the server doesn’t have the best power consumption, so I’d like to use WoL to remotely turn it on.

When you say remotely you mean over the internet, right? Or did you mean remotely within the same LAN e.g. from your living room or wherever.

By default WOL doesn't work over the internet AFAIK. The wikipedia page mentions it a bit https://en.wikipedia.org/wiki/Wake-on-LAN#Subnet_directed_broadcasts

Like others said you may be able to get that going with a VPN or anything VPN-like that allows broadcasts between connected systems. Or if your motherboard supports IPMI / IMM you should be able to connect to the system & perform power functions that way.

In my case my motherboard doesn't have those sort of management functions so in the end I settled on logging into my router remotely & initiated WOL through there. That could be another option for you if your network router is capable of sending WOL packets to the LAN.

However, the server doesn’t have the best power consumption, so I’d like to use WoL to remotely turn it on.

I was using windows desktop machines with teamviewer and anydesk and both could wol without port forwarding. Recently I switched to linux and rustdesk and I couldnt figure out how to do the same. So I got workaround, using upsnap docker container that has simple gui with button to turn on devices over wol. So i login to upsnap, turn on machine and then login with remote control. Still looking for all in one solution. I use wireguard to connect to upsnap (wg port open) but Im using it for other services as well.

Other than bios, I remember I had to enable WOL in windows to make it work, not sure is it different for win server.
