 ## How to make your node routable
 
 - make sure the computer on which the node is running has a static public IP address (IPv4 or IPv6). You can retrieve the
-public IP address of your computer by opening ipify
+public IP address of your computer by opening ipify (https://api.ipify.org or https://api64.ipify.org)
 - if the computer running the node is behind a router/NAT, you will need to configure your router:
     - if the router uses DHCP, the MAC address of the computer running the node must be set to have a permanent DHCP
     lease (a local IP address that never changes, usually of form 192.168.X.XX)
     - incoming connections on TCP ports 31244 and 31245 must be directed towards the local IP address of the computer
     running the node
 - setup the firewall on your computer to allow incoming TCP connections on ports 31244 and 31245 (example: `ufw allow
 31244 && ufw allow 31245` on Ubuntu, or set up the Windows Firewall on Windows)
+- you can then test if your ports are open by typing your public IP address and port 31244 in https://portchecker.co (then again

 - edit the file `massa-node/config/config.toml` (or create it if absent) with the following contents:
 ``` toml
 [protocol]
 routable_ip = "AAA.BBB.CCC.DDD"
 ```
 where `AAA.BBB.CCC.DDD` should be replaced with your public IP address (not the local one !). IPV6 is also supported.
 - run the massa node

+- Additionally, in your massa-client, you can check that the `get_status` command shows your `Node's IP: <your_public_ip_address>`.
+If it shows `No routable IP set` instead, please check again your configuration.
