Remote access to computing infrastructure is a key feature of Parallels RAS.
Secure access to your Windows Desktop remotely is as easy as this:
Using a web browser:
This example shows the Firefox browser. Other browsers are slightly different.
Browse to your assigned remote access
URL
Add a security exception for a self-signed cert (if used)
Log in to the Parallels Secure
RAS Gateway
When connecting via the web gateway, Parallels
RAS will check to see if you have a Parallels
RAS Client already installed. If it is, you will probably get the
best performance by using it. However, you can select to
use the HTML5 (web browser) Client for maximum convenience (you won't have to install any software on the PC).
You would probably choose the HTML5 Client if you are using a borrowed PC.
