I'm not sure on your second question as I do not see a
getHostAddress()
method in the FTPSession. Please clarify further.
Oops, I meant FTPSession.getServerAddress.
Here's the behavior that I see for each, using this basic flow (please
correct me if I have over simplified things and that I'm wrong in
describing it this way):
Server's Local IP (1.1.1.1) <-NAT-> Server's External IP (2.2.2.2) <--
> User's router/public IP (3.3.3.3) <-NAT-> User's local IP (4.4.4.4)
FTPSession.getClientAddress: Server's External IP (2.2.2.2)
FTPSession:getServerAddress: Server's Local IP (1.1.1.1)
I would've expected FTPSession.getClientAddress to return User's
router/public IP of 3.3.3.3. I suppose it returns 2.2.2.2 instead
because the server is behind a NAT/firewall, and the last IP that it
knows that it's coming from is the one immediately behind the NAT. Is
that correct?
Thanks!

Hey all,
It seems like if I do ftpSession.getClientAddress().toString() in
an Ftplet
methods (onLogin, etc.), it won't get the actual user's address for
me. I'm
wondering if that is because of NATs/Firewalls/etc., or if it's a
bug? It
seems to get the last address the "hop" came from, rather than the
original
origin.
On the side note, if I do ftpSessoin.getHostAddress().toString(),
it'll get
the internal IP, rather than the external IP address that the user
used to
ftp to that machine. Is that also behaving the way it's supposed to
work?
Thanks!
