My Nat type has been showing as strict/moderate since getting the 1703 update, after my console updated today it still showing as strict. My second xbox on the 1610 update is showing as nat type open. I've reported it from the console when both were on the same update both had open nat types, my service provider is sky I have been with them for several years with no problems I use the sky hub SR102 and have recently had a new one sent out and still am getting a strict nat type on the xbox on 1703 update and the second xbox on 1610 still shows a open nat type.
