I have been unable to play games online with friends due to NAT problems, and a solution that I've found from multiple sources (including the router company) is to try to port-forward the console (Many other solutions I've tried have not worked, and this seems to be one of the only remaining ones that shows promise).
From the research I've done on this, I understand that this effectively puts the console outside of the router's security, and allows outside parties to initiate communications with it. From what I read, this shouldn't be too risky to the console itself, as most of them use proprietary code and operating systems. My main concern is whether a third party could target this Console and use it as a bridge to get into the LAN. I'm wondering how likely/ possible something like that may be.
Basically, I would like to know what kind of risk a port-forwarded console could pose to other devices that are on my network.
