Could someone kindly post a general ISPConfig3 web server firewall configuration for Bastille Firewall.... thank you in advance.
I'm not sure I understand what you're wanting, but ports to allow for any firewall would be 80 and 443 for web, 22 for ssh, and 21 plus a range of ports (for passive mode data connections) for ftp. If you run the ispconfig interface on that same web server, you would need port 8080, if that's where ispconfig runs. And port 3306 for mysql connections from any slave ISPConfig servers. A last note, unless you know a very specific/good reason you need bastille, you should use ufw, which is nor feature-full, creates a better firewall rule set, and id's current/supported. I believe bastille is no longer maintained/updated, and may not be officially supported in ISPConfig anymore.
