Since installing 13.0.208.000, FTP connections with Windows XP FTP client (ftp.exe) have failed after login to the FTP server with ZAISS blocking PORT command packets from the local machine to the server port 20. Not the return packets, but the PORT command packets attempting to leave the local machine themselves.
Failed attempts at solution:
1) Firewall Settings -> Advanced -> Allow uncommon protocols at high security, checked
2) Application Control Settings -> View Programs -> File Transfer Program -> Options -> Expert Rules -> Add (Source: My Computer, Protocol: TCP and UDP, Destination Port: FTP Data)
