Web Appliance and SFTP

We use the appliance as an explicit proxy over 8080. Trialling a print driver which uploads documents via SFTP to a bulk-mailing third party and I've tried all sorts of things to get the upload to work through the appliance. The company have reconfigured the product to send the data to port 8080 instead of 22 (more as an experiment than anything), and I've set up my IP address within the appliance to bypass authentication, and have also tried listing the EXE as one to allow through without authentication (albeit merely by listing the exe as an app). But still no joy.

We had something similar with Sage Payroll's HMRC Mailbox submission component in that it wasn't expecting to hit an NTLM proxy, but by enabling the bypass of 'apps without user agents' in the authentication section, this was resolved.

Just wondering if anyone has any other suggestions. I've tried allowing through .NET applications as well, thinking that might help.

I've reconfigured our firewall to allow port 22 to their sftp server and if I configure my PC to go directly to the net, the submission works. But I can't allow that for the users, they have to go through the appliance.

Thanks for any advice!

  • Hi Mark,

    The appliance only supports FTP over HTTP and won't support native SFTP.  So if the vendor has just pointed their normal port 22 SFTP traffic to port 8080 on the appliance instead, the proxy won't understand it.  

    Really, if the application only does native SFTP it should just bypass the proxy completely and go direct over port 22.  It *should* ignore your proxy settings... Are you saying you have to disable the proxy settings in your web browser to make this application work?

    Cheers,

    Tom.
