And while I'm pretty adepts at networking as I wrote router code in the 90's I still didn't get what you needed to do.
I think you need to task your IT team to deal with this. It might require better gear like managed switches that only allow this or that.
I run a small business that deals with sales of services in MMORPG games. Here is my situation: Currently action is taken against certain services that I am trying to offer my customers in the game, although this service is not directly mentioned to be against the game's policy or "against the rules". They simply want to keep the item achieved through the game as unique as possible, as it is extremely difficult to achieve. The problem is that if I offered this specific service traditionally, it would result later in the removal of the item I acquire for my customers if it was detected not to be completed by themselves. This is closely monitored by the game's employees. Most likely this is traced through IP logs.
So the question at hand is.. is it possible to spoof a certain IP with the other person giving me permission? Or is it possible to connect to this persons IP remotely so it looks as if I am providing the service for them off their own connection? Would this be a stable and decent connection? And Is there a simple way to do this? or possibly a program I could use that would be simple for the customer to set up to on their end to allow me a connection (or a fake connection) to their IP? I know you can use Remote Desktop, such as teamviewer and do just that through their ip, but the frame lag is too great for me on all these Remote Desktop programs to do the task at hand. So is there not a way to connect to someone the same way Remote Desktop is used, but only connect to their IP and not their entire Desktop PC mirrored? I am willing to even pay for such a program and have been looking everywhere for answers. All help is appreciated, thank you.
