Aktuelles ISPConfig auf Ubuntu 16.10
Serverkonfiguration > Firewall: ufw (wurde nicht geändert)
Einträge > TCP: 20,21,22,25,53,80,81,110,143,443,587,993,995,3306,8080,8081
Einträge > UDP: 53,3306
ufw in der Shell enabled, Plugin gesymlinkt, Einträge gelöscht und zugefügt (muss man auch alles erst mal wissen).

Ports wie zB 80 und 443 gehorchen diesen Einstellungen, werden geblockt, wenn man sie aus der Liste entfernt.

Andere Ports (zB 9200 - Elasticsearch) sind immer offen, obwohl sie es nicht sein sollten...

$ ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), deny (routed)
New profiles: skip
