I've got a Win2K client on the Internet trying to initiate an FTP connection to a Win2K FTP server on the Internal network (Inside Interface). Short of posting tons of TCP dumps & sniffer info, some packets pass back & forth, but a complete connection is not established, to actually move any data.
I need to mention that the FTP server sits behind a Nokia appliance running Checkpoint; the packets must first pass thru my PIX 525 running 6.2(2). FTP Fixup is enabled on port 21.
FTP Client--->PIX FW ----> Nokia FW ----> FTP Server
I know this is a fairly generic & general description, but does this raise any red-flags with anyone?
