The firewall in ispconfig 3 is kind of basic no geo blocking is there a way to disable ispconfig 3 firewall and install cfs instead?.
looks like bastille firewall is gone websites are all gone or down odd it has not been updated in some time.
You can use any Firewall with ispconfig but only Bastille Firewall and UFW in ispconfig. So as long as you dont activate the firewall in ispconfig, you can use the csf firewall on your server.
But thats not caused by deactivating the firewall. Which is the exact error message that you get in the bwowser when you access one of your sites?
