Right. What is the topology of this setup? Is the client behind WG of the server behind WG?

[budg4]

it is the client behind wingate, the as400 is behind NAT with a router

[genie]

Sorry, I re-read the first message and found the answer there. Looks like the FTP server is blocked by another firewall - can you connect to this FTP server without being behind Wingate?

[budg4]

yes i can enter directly on internet, but not bypass wingate.

i can give you the ip and the login / password to test (in private)

Right. Tried it - it worked.....
What client are you using?

[budg4]

normally i use IE for access at this page with a link ftp://IP3**********@*.no-ip.com . i have use a client ftp for have a log, it is smartFTP.

Can you test with Internet Explorer bypass Wingate to access at this link ftp://IP3**********@*.no-ip.com with the www proxy server.

Thanks

I can but only tomorrow morning.
I suspect I know what's happening there, so I'll get back to you in a couple of hours.
