If you want to access Atsumeru server outside of local network, it is strongly recommended to protect requests to it with https (especially since the main authorization method is Basic)

Spring Boot (opens new window), which is the heart of server, supports https out of the box, but you must configure it yourself, and self-signed and Let's Encrypt (opens new window) certificates are not supported

# Reverse Proxy

The best option is to use CloudFlare Reverse Proxy, CloudFlare Tunnel or Caddy

Any of the above methods will require your own domain name with ability to change NS-server

# CloudFlare Reverse Proxy

HTTPS certificate will be issued for free and automatical

This method only works if you have a static/white IP and with ports 80, 8080 or 443. If your server is behind NAT or you want to use a different port, use CloudFlare Tunnel

  • You need to register in CloudFlare (opens new window)
  • Click Add Site button on the quick access panel
  • Follow instructions to add and configure your domain
  • Open control panel
  • Go to DNS section
  • Set up a redirect to the actual server address

It is also possible (and preferable) to enable requests proxying to cache them in CloudFlare and hide the real IP/address of server

# CloudFlare Tunnel

HTTPS certificate will be issued for free and automatical

  • You need to register in CloudFlare Zero Trust (opens new window)
  • Open Access section
  • Open Tunnel subsection
  • Click on Create a tunnel and follow instructions to create a tunnel
  • After tunnel is created and connector is activated, open created tunnel in control panel
  • In Public Hostnames tab add your domain specifying the IP/address of server and its port

If necessary, in Public Hostnames tab you can add subdomains for your domain, setting a different IP/server address or port

# Caddy

Caddy (opens new window) supports automatic generation of Let's Encrypt (opens new window) certificates

You need to install Caddy (opens new window)

Configuration examples:

# Caddy (v2):

<your domain> {
  reverse_proxy http://<ip/server address>:<port>


  [email protected]
  http_port 80
  https_port 443

<your domain> {
  reverse_proxy http://<ip/server address>:<port>
