Hi guys, stupid question I think, as it relates to a windows feature put to use in FreeBSD, but I beg you not to bite my head off for this ;-) Once upon a time, I was using pcconseal firewall (its too bad its not around like it used to be, it was a pretty good windows firewall program). What I remember about it was that it used to "know" what programs were opening the ports in question. Now I'm setting up a firewall on a gateway for my LAN. This sort of characteristic would be a great help, imho (of course I have more limited knowledge in UNIX), for properly allowing passive ftp transfers through. I'm messing with IPFilter at the moment, I'm wondering if there's a way, in FreeBSD for it (or any other firewalls?) to know what service is opening a port, so that it may be opened only for a particular service. Or is that something that should be defined within the ftpd itself (I'm not talking about setting a specific portrange for passive transfers... a little more than just that... making sure that only ftpd can use say ports 15000-19000 outbound) Thanks in advance...
