FTP Client not working || Bypass Proxy

[Arpit Dave]

Hi Team,

One of my customer is looking to bypass FTP Client in Proxy solutions. 

Can you please guide how we cab do this. 

I have bypass proxy service from service tab.

Hi Arpit,

How is the client configured? Is this explicitly deployed (client uses browser proxy settings, PAC file, etc)? or is it transparently deployed (inline, WCCP, etc)?

The reason I ask is because when you set a service listener to bypass, the proxy will pass the packet to the next hop without applying any policy. In an explicit deployment, the client computer is putting the proxy IP as the destination IP address on the packet, making the proxy the final destination of the packet. In this case, if you set the service listener to bypass, there is no where to pass the packet to, and the connection fails.

If this is an explicit deployment and you want to bypass the proxy for certain traffic, you would want to change the proxy settings on the client machine, or make modifications to a PAC file to not have the specific traffic proxied. 

More on bypassing in and explicit environment can be found here.

Hi Jacob,

Thanks for Reply.

Currently, customer have deploy the solutions in explicit mode with PAC file. We have try to bypass the proxy service in bluecoat but customer using FTP 21 with SSL.

How to allow this.
