I have a problem with checkpoint firewall-1 (FTP) by upload and download.
Authentication - OK.
...
TCP PRINT hSocket, "TYPE I" <-- Ok
...
TCP PRINT hSocket, "PASV" <-- Ok
...
TCP OPEN PORT ... AT ... AS hSocket <-- open data port on Firewall, Ok
...
TCP PRINT hSocket, "STOR " + remoteFile <-- Firewall blocked this command with
550 Security server forbids STOR before PORT/PASV.
I have no problem with ftp-proxy servers. Data communication (upload/download) works fine.
Is this false command sequence for checkpoint firewall-1?
Where is mistake in this procedure?
Thanks
