RE: Can't access FTP sites requiring authentication

Hello Terence,
I did not get the chance to try your steps yet. I intend to do this today.
I was only stating the fact that I had already tried beforehand the
'ftp://user:pwd@xxxxxxxxxxxxxxx/' but it does not allow me to upload anything.
I will definitely try your steps today. I will send you all required logs
and post my results.
Thank you for your time.

I'm glad to hear that you can upload file to the FTP site now.

I am just writing to see whether there is anything further I can do for
you. If you have any concerns on this thread, please feel free to let me
know. I am glad to be of assistance. :-)

Thank you and have a nice day,

DOES
| NOT allow me to post and/or upload any files whereas outside of our LAN,
we

| Please advise. Thank you.
