COD and Bufferbloat / Double NAT

[SevenDeviations]

I was wondering how big of a deal Double NAT is when it comes to games like COD. Right now I have my R2 connected to my other router, not in DMZ , so I have double NAT. I don't have access to the first router's settings, as they are managed by the house owner.

My bufferbloat is consistently in the A to A+ range when I have the double NAT R2 plugged in, as opposed to when I plug directly into my ISP router my bufferbloat is a D score.

My question is does double NAT really introduce any hidden network latency that would effect things like hit detection etc.? On my R2 I have my QOS capped at 10mbps and 10mbps down and generally have the best results with that.

No it doesn't really, NAT is important as it determines who you're able to connect to but given most games are using servers now it's not that much of a problem. Even in private chats/parties I think they route you through a server now as well but in some cases that might be where you notice it most prominently.
