I've got a PIX 515 v7.2.1 configured as just a firewall (no nat). We are experiencing issues with FTP outbound. We can connect to one FTP site without issues (doesn't matter which, just the first one we connect to). When we attempt to connect to others after this they are disconnected after attempting to connect. If we reboot the pix, we can connect to a different FTP server, but once again no more than 1.
Config:
PIX Version 7.2(1)
