ec2 windows server with working public ip .

That was a vague answer . my question is not whether the windows instance has an internet connection ( that is obvious). My question is that i want the windows ip to be a public ip . how do i set the network interfaces ? . if there still will be a a private ip , i need that the public ip will forward to the private ip , and the other way ... like ngrok .

why is there an option not to create a private subnet , and an option to attach the elastic ip to an instance (not to a network interface ) ?

My main focus is now that i cant seem to create an instance that can be accessed on rdp .

Thanks very much , Yes , that was the issue , an RDP rule for my ip that i am connecting from . But again , i messed everything trying to get a public ip recognized by windows . so my routine would be now , delete the instance , delete vpc ( and all associated ) , create a vpc with all associated ( an option for NAT) + RDP rule , not sure if now is the elastic ip creation , create the windows instance. maybe now is the elastic ip allocation step , here is where i really get lost , in this point do i have an elastic ip network interface ( that has the elastic ip ) and also a nat network interface that may have an elastic ip ? , where does the elastic ip goes ? , do i need the 2 network interfaces for the windows to recognize the public ip ?

In assigning a public ip (also elastic/static ip) i have already succeeded before . Windows cant see this public ip , i guess that this is where the nat takes place ??? This is my problem .

My question is that i want the windows ip to be a public ip . how do i set the network interfaces ? . if there still will be a a private ip , i need that the public ip will forward to the private ip , and the other way ... like ngrok .

What about forwarding like ngrok ? public to private forwarding .

What about forwarding like ngrok ? public to private forwarding .

i dont want to use ngrok. this is just an example what i want to do . i want to forward the public ip to the private ip . HOW TO DO IT WITH AMAZON AWS EC2 ? if you dont know . write me that you dont know , and let other people answer . up until now all your answers regrading this issue where not to the point . This port forwarding is the whole essence existence of amazon aws . they wouldn't be if this would not be possible.
