Resolved No Firewall in Plesk

[stevland]

I recently migrated from a VPS with Plesk 12.5.

My current setup:

‪CentOS Linux 7.3.1611 (Core)‬
Plesk Onyx Version 17.0.17 Update #11

There is no Firewall listed under Tools & Settings > Security.

Is that because my default CentOS 7 installation already had Firewalld enabled before I installed Plesk Onyx?

I'm also confused about who is managing my ProFTPD service... is it Plesk or CentOS 7?

I have psa-proftpd 1.3.5b-cos7.build1700161026.16 listed under Tools & Settings > Plesk Components.

But there is nothing related to FTP under Tools & Settings > Services.

All of my hosting accounts are intermittently getting "failed to retrieve directory listing" when connecting via FTP and I am spinning my wheels trying to resolve it!

Nevermind.

It turns out the the issue is local to my router. If I put my computer into a DMZ I have no trouble using FTP.

Meh. I have never encountered an FTP / router issue like this one. It just happened to coincide with my new VPS. But it turns out to have nothing to do with Plesk or CentOS.
