Hello,
I'm a R3 user. So I recently ran into an issue. I switched from my regional cable ISP to my regional telephone/fiber ISP and I'm trying to have an open NAT. I have the ISP ONT connected via ethernet going straight into the provided fiber ISP router and then from the ISP router going into the R3. But just recently I started receiving a "Invalid Socket Family Settings". It happens after I close the COD app to go to a different game within the COD HQ (MW2) or after an update. I could reset my R3 and I would be able to get into MW3. But I have to do that every time. The issue started after I switched to my fiber ISP. Now if I turn all the ports off or delete them on the ISP router and R3, my NAT goes back to moderate and the Call Of Duty games boot up as normal without the error message.
My Xbox Series X and PlayStation 5 are hooked up to my R3 and are moderate (NAT) but don't have any issues with them. Those devices boot COD up fine. So I'm thinking it's either the ports I'm using on the fiber ISP provided router and R3 are incorrect or it's some setting on my PC that's wrong. I tried changing my DNS on my PC to 1.1.1.1 or 8.8.8.8 and that worked for a little but I still keep getting "Invalid Socket Family Settings" error message.
The ports I have set up on the fiber ISP router and R3 are:
TCP: 3074, 3075, 27015-27030, 27036-27037
UDP: 3074, 4380, 27000-27036
Any help would be appreciated.
Thanks in advance and the R3 so far has been awesome.
