DSpace 7 Installation on Virtualbox

[Peter Homor]

Hello,

I've installed both Dspace 7 backend and frontend on my notebook (Windows 10) using Virtualbox. The guest is Ubuntu desktop 20.04. The backend works well in the host browser (localhost:8080, localhost 8983), but the frontend'S URL (localhost:4000) works only inside the guest machine's browser. I try NAT&port forwarding and Virtual Hosty-Only networks too. I tried turning off the my Symantec security system also. Neither solved the problem.  

Would you help me to find the solution? 

Thanks, 

Peter
