@hescominsoon said in Why Pfsense is free and who is mysterious benefactor we should be grateful ?:
yes it could..but why? That would lead to it being more insecure by default.
That was just to demonstrate my point that pfsense is just an interface on top of BSD and does nothing that couldn't be done by BSD alone. It would mean manually configuring all the various services, including pf, but it could be done. It's the same on Linux, where the configuration app (Yast) configures everything, including IPTables. Without that app, you could still make a good firewall, but it would take more work.
BTW, I go back to the days when everything on computers was done from the command line (I was working with VAX/VMS long before I ever saw PC/MS-DOS and IBM mainframes before I bought my XT clone) and when I first heard about the Mac, I wondered why anyone would need a graphical interface.
Putting Wireshark would take a lot more work than I'm prepared to do. I do use Packet Capture frequently and download the captures to examine with Wireshark. I can also put a managed switch, configured as a data tap in line with any connection to pfsense.
