Installing and Playing DS2 with Original Disc's & MP/Internet

Hello everybody! I'm new user here in SiegeTheDay... I hope that some of you can help me. By helping me, for sure you'll be helping others...

Let's straight to the point. I'm trying to make DS2 Multiplayer/Internet (not network!) works without any third applications (gameranger, hamachi, etc). Yes, I think it's possible! I made it with DS_LOA with my friends...

However, for some Reason, with DS2 (patched to v2.2) when I open the game, click on Multiplayer, then Internet... I always receive a message saying "Unable to connect". It's not a firewall problem or a Windows Incompatibility... I've already tested in XP, 7 and 10. My game isn't original... =/

The only possible explanation it's about to use Original Disks for installation and maybe playing. So... here it goes my asking...

Please, could anyone here install the Game DS2 (Only) using original disc's, patch the game to v2.2, keep using the disc's and open the game, and go to Multiplayer/Internet (not Network) and test if you can open the Room?

I would be very grateful.
