I have an ASUS RT-AC3200 router and when I am trying to use my xbox I am always on a strict NAT type and it is because it says I have a double NAT. I have been on google and tried pretty much everything with no luck. I live in an apartment complex so we have an ISP that is used throughout the entire complex for free so right now I have my router plugged directly through an Ethernet cable and into the wall. I really don't want to contact my ISP because they don't deal with customers of the apartment complex they only deal with the business directly which would be my apartment manager. I was just seeing if anyone had any ideas on how to fix this.
