## Solution

The Beyond attachment tool handles file transfers within Service Requests (SRs). By default, these transfers go through HTTPS on port 443 of your Check Point computer. No additional configuration is required for this communication.  

You can accelerate these transfers using IBM Aspera Connect. Aspera Connect maximizes speed while maintaining the highest security, regardless of file size, transfer distance and network conditions. Aspera Connect uses IBM's patented FASP protocol over UDP port 33001 on your Check Point computer. To use Aspera connect, you must download the IBM Aspera Extension client to your web browser and allow outgoing traffic from your Check Point computer on ports TCP/33001 and UDP/33001

**To use Aspera Connect for accelerated file transfers in the Beyond attachment tool:**

1. Add the **IBM Aspera Extension** and **Aspera Connect** (2 steps) to your browser.  
   The extensions are specific to the browser; the procedure to add an extension to a browser is the same regardless of which OS platform that browser uses.
