I'd like to use 2 Xbox Ones on Xbox Live behind a single ISP (Comcast). My networking gear is Mikrotik and supports Port Mirroring.
Would mirroring (which I see is usually used for monitoring traffic) be a solution to "forward" ports to two devices?
My rough understanding makes it seem like each Xbox's network traffic would effectively be spamming the other Xbox (but it would just drop the inappropriate traffic, and be fine). If that understanding is close to reality, what would problems would it encounter (would they each start blasting a bunch of NAKs and throttling each other) and is there a way to mitigate?
