- Plesk Onyx 17.5 for Linux
iptables-servicespackage is installed.
- Plesk Firewall rules are flushed from iptables if restart or reload the iptables service.
This is Plesk bug with ID PPPM-7293 which is planned to be fixed in future product updates.
As a workaround:
Connect to the server using SSH .
Download attached file , unpack and execute it:
# wget https://plesk.zendesk.com/hc/article_attachments/115003630473/WA-PPPM-7293.tar.gz
# tar -xvzf WA-PPPM-7293.tar.gz
In order to remove workaround, detele created service file:
# rm -f /etc/systemd/system/iptables.service
