# Documentation for Hemera Network and Hemera Link
Hemera Network is a private network based on Netmaker to allow users to connect to a subnet behind a NAT.
Devices act either as coordination nodes, hosts, or clients.
- Coordination devices are available via a public IP and have ports open to the outside world. They handle connections between devices that are behind a NAT.
- Hosts are nodes that are behind a firewall that can act as gateways for their subnet or act as standalone machines that are accesable by other devices on the network.
- Clients are stock wireguard clients and need a Coordination node to proxy all data through them, when connected via wireguard your data enters through a coordination node and exits through a host that has signed up to be an exit node for a given network.
Based on Hugo and the ["Stack"](https://github.com/CaiJimmy/hugo-theme-stack) theme from CaiJimmy on Github.
