For those of you that play Ghost of Tsushima I'm having this issue when I'm trying to play with a friend on the NetDuma R2. I did notice that on CoD: MW that my NAT type says Open when I play with my Xfi Modem/Router combo. When I use the R2 I notice that it shifts to Moderate on CoD. I figure it must be a NAT thing because when I play Ghost through the Xfi gear, I can invite and play with the friend. On the R2 it won't let us connect. I have UPnP enabled on the R2 and disabled on the XFi. Has anybody else figured out how to get around this issue?
I don't know if it means much, but me and this same person can play Apex, Rogue Company, and I believe Rocket League together with no issue through the R2. I haven't tried recently, but I also noticed that I couldn't play Drop Ins on Fifa 21 through the R2 as well.
