Remote Web Workplace

Ok I have an issue that I just can’t seem to solve!!! Begging for help if anyone has the time. I am currently the admin for a SBS203 environment, which I set up. We are trying to get the remote web workplace to function and I am having some issues. I can get in to the server from RWW, but not to the clients listed on the page. I have the port 4125 forwarded and 3389, not sure why this won’t work. HELP PLEASE?!?
