+Nothing is eternal, especially the relevance of documentation. I think help.ubuntu.com is an absolute winner, holding the largest number of outdated and irrelevant pages. But that's not a topic for today's post.
+One of my Proxmox cluster nodes can't power itself on after the outage. But it supports wake-on-LAN, so I decided that another node could power it on. And the simplicity of this task was overrated by me.
+
+<!-- truncate -->
+
+:::warning
+
+Wake on LAN doesn't work across VLANs. Magic packets could be sent and received only inside a single subnet.
+
+:::
+
+## The victim
+
+First of all, even after enabling "Wake up on PCI event" or something in BIOS it was not working because WoL was still disabled on a software level. It can be checked with: 
+
+```bash
+ethtool enp1s0
+```
+
+Where `enp1s0` is a physical network interface of a Proxmox node, not a bridge.
+
+There should be `Wake-on:` setting among others. In my case it was `Wake-on: d`, which means that wake-on-LAN is disabled, according to `ethtool` documentation:
+
+```
+p  Wake on phy activity
+u  Wake on unicast messages
+m  Wake on multicast messages
+b  Wake on broadcast messages
+a  Wake on ARP
+g  Wake on MagicPacket(tm)
+s  Enable SecureOn(tm) password for MagicPacket(tm)
+d  Disable (wake on nothing).  This option clears  all  previous
+    options.
+```
+
+We need to set it to wake by the MagicPacket(tm). We need to create a config file for this to be enabled on system start. But first we need to:
+
+```bash
+ip link show enp1s0
+```
+
+and write down our network device MAC address. Then create a file:
+
+```bash
+nano /etc/systemd/network/90-wakeonlan.link
+```
+
+with the next content:
+
+```
+[Match]
+MACAddress=<mac-address-here>
+
+[Link]
+NamePolicy=kernel database onboard slot path
+MACAddressPolicy=persistent
+WakeOnLan=magic
+```
+
+After that we need to reboot and check WOL status again:
+
+```bash
+ethtool enp1s0
+```
+
+Now `Wake-on` should be set to `g`.
+
+## The one who bothering
+
+On another node we need to install an util that will be sending a magic packet:
+
+```bash
+apt update
+apt install etherwake
+```
+
+Now we can power the victim off and try to wake it with:
+
+```bash
+etherwake -i vmbr0 <mac_address>
+```
+
+Where `vmbr0` is a bridge network interface of current Proxmox node, and `<mac_address>` is a MAC address of the victim's physical network interface.
+
+If it works, we can now add a cron job to wake our victim upon current node startup, adding some delay to make sure the network is ready:
+
+```bash
+crontab -e
+```
+
+Cron job line to add:
+
+```
+@reboot sleep 30s && /usr/sbin/etherwake -i vmbr0 <mac_address>
+```

+This is my project of publicly available documentation of my home servers and self-hosted services.
 
-Working on it...
+## Network
+
+The gate to my HomeLab is a **UniFi Cloud Gateway Ultra**. It is connected to a **1 Gbps** fiber optic from my ISP and manages **3 static WAN IP** addresses.
+
+The local network is separated into **four VLANs**.
+
+The gateway is also a DNS server for all local network and VPN clients.
+
+WiFi network is delivered by **two UniFi U6+** access points powered with the **Switch Lite 8 PoE**.
+
+[More on network](network.md)
+
+## Servers
+My family home cloud is provided by the **Synology DS423+**. It is for photos and documents hosting and sharing.
+
+I also have a **DIY NAS with TrueNAS Community Edition** on it that hosts most of the services for personal and family use, that are not from Synology.
+
+The third one is the **Asus PN42** min PC with an Intel N100 CPU with the **Proxomox VE** on it. It hosts public services, like this website, my Gitea instance, and others.
+
+I also have a mighty **Home Assistant Blue** with... well **Home Assistant** on it. It does not depend on other servers and has a separate Cloudflare tunnel to it from the outside to be available even when all other servers fail.
