Ftp is. Telnet is not. That's why telnet really should work; it's just
a single-stream connection. Ftp, using multiple streams, is more
problematic.

In your first message, you said that you get nothing after the password
prompt when telneting, but it sounds like you're getting further than
that, if you are able to type 'pine' and 'ls -l' commands.

Both of these commands cause a large amount of text to be sent at once.
Likewise, the 'dir' command in ftp might send a small amount of data,
while the 'get' command might require a larger amount to be transmitted.

That number, 61005, is in the "masquerade" port range. Hmm. Is that
the IP address of the masq box, shown? If so, I think that is correct
output.

I think it's probably more a problem when a large amount of data needs
to be sent. That points to something like an IP fragmentation problem,
perhaps related to MTU sizes. Maybe some other list-member can offer
some advice in this regard.
