Hey guys/gals,

-> I'm doing some FireWall testing on one of my servers and while scanning the machine with different scan types... i noticed that the FIN scan (using nmap) came back with all open ports... I mean everything from 1 to 31337 was listed as open. Obviously i know this not to be true... I'm trying to figure out why nmap would say this...

-> I'm using a FreeBSD machine as the Firewall/NAT
-> All of the servers are up-to-date Win2k Servers

---------------------------------------------------->
now, same with UDP scan... all UDP ports are listed as open?
only -sS and -sT scan types seem to be working?
