I wanted to use a different firewall, so I checked what firewalld rules were active on my fresh install and compared them to the list of ports displayed at the end of the installation.
This is a screenshot of a YouTube video, I did not screenshot my own.
I noticed there were 2 firewall rules active that were not in this list:
- 7080 for OLS
- 995 for mail
So this built in piece of documentation is likely outdated.
