PA-220 fw for internet access. An old workhorse, Synology DS1812+, for filesharing. A mac mini with Ubuntu running Plex and Roon also hosting Dashy in docker. A Hwg-ste to measure temp in my cabinet. I host a RIPE probe. An RPI4 running Zabbix. My next project is moving from PA-220 to something in the 400 series (probably 415) so I can upgrade to newer PANOS.
