RDP does not simulate an other machine with an other ip adress, it just allows you to have an other session on the same. Hence regarding CCP you have the same ip adress for each desktop, then for each Eve process. => issue with alpha accounts.
I also tried with multiple IP addresses through a vpn and I could not get an alpha and omega account to reliably connect. I believe I did have both on at same time once but can’t remember what I did to make that happen.
I think it might have been a Virtual machine and your regular windows account.
But Bitenbois is correct RDP doesn’t work with alpha and omega accounts.
All this does is allow you to run several separate EVE instances that each has their own mouse/keyboard input for automation.
This does indeed not hide or mask your IP, if you are worried about your accounts don’t bot
