Hello everyone, While updating ISPConfig today, I saw this: Code: [...] Reconfigure Permissions in master database? (yes,no) [no]: yes Service 'firewall_server' has been detected (currently disabled) do you want to enable and configure it? (yes,no) [no]: [...] I'm unsure what this is about, could you please tell me what "firewall_server" is supposed to do? I initially followed the instructions to install "the perfect server" so I'm wondering if I missed something and if I should consider activating it? And just to let you guys know, it's a multiserver install on Debian Jessie with 2 servers running all services. Any comments and advice welcome. Thanks!
