The very first pflog0 entry is:
Code:
rule 0/(match) block out on rl0: 192.168.191.254.26486 > 192.168.192.115.21:
Rule #0 is your first filter rule: "block log all". This is traffic from a high number, random port from a computer at the factory, destined to port 21, the FTP control port, on your FTP server at 192.168.192.115.
There is no pass rule matching this traffic.
