Auto open/close 80 port for letsencrypt challenge certificate renew

[Enrique Garcia Polo]

Hi

I want to use port 80 challenge with letsencrypt proxmox certificate update automatically but I wan't have port 80 open alltime. Searching I have found a certbot script with pre and post commands that opens and closes 80 port in the router via uPnp (https://darjchen.medium.com/using-certbot-http-01-challenge-using-upnp-on-a-home-router-2f51a88bb9b5).

Is it possible to do the same in Proxmox?
Is there any script file that I can modify to do this? I understand that the gui bottom "request certificate now" starts the certbot script, isn't it?


Thanks for any answer.

Best regards,

I have found the command:
pvenode acme cert renew

I installed miniupnpc, and I have written a mini script like this:

#!/bin/bash

upnpc -a 192.168.2.180 80 80 tcp
pvenode acme cert renew
upnpc -d 80 tcp

but my router (wich has upnp activated) answer me: 606 Action Unathorized....
