Reverse proxy to application

Hi everybody

I have a synology and I want to link a subdomain to one on this application. This is the url I usually use to acces to this service :

192.168.0.17:5001//index.cgi?launchApp=SYNO.SDS.App.FileStation3.Instance&launchParam=openfile%3D%252FOliver%252F

But this i too long and I want to acces it directly this mydomaine.com

How should I configure the server ?

Thanks a lot for your help !
