Am I sure? Well, I'm telling TidFTP to use passive. Also, FileZilla shows
in detail the commands and responses. Clearly, it sets PASV and gets a
response. Then when it tries to LIST, the server never responds.
Unfortunately, I haven't got that kind of instrumentation in my app, but "it
seems reasonable" that the same cause is blocking both filezilla and my app,
since they both worked fine before. On the other hand, sonicwall is adamant
that they CAN connect to our server through the same firewall and transfer
files using whatever client they are using. Seems pretty clear that the
clients are handling passive differently.
