I'm struggling to get my head round this whole NAT thing with my MR600. I understand what NAT is but just want to understand how my router deals with it all:
In the WAN interface of the router settings there is a button to turn NAT on or off. But isn't NAT on 4G routers a weird type of double NAT called CGNAT? Coupled with a ever changing IP address, this is the reason for NAT issues in online games? So seems a bit too good to be true to have an on/off button. It's on by default but surely people would want this off?
Will turning it off affect my Upnp which seems to be doing its job in automatically letting through Call of Duty via the ports.
My main questions really are:
- Will turning off NAT in my router help to give me open NAT in games? (see screenshot of NAT on or off)
- Should I turn off NAT boost (as i dont get over 100mbps where i read its only useful for?) and opt for QoS?
- Is QoS worth the effort? Looks like complex and all I'd want it for is prioritising my gaming PC.
- Does NAT Boost have anything to do with NAT in terms of opening/closing ports for things like gaming?
- Will my uPnp be affected by messing about with either my NAT on/off or NAT Boost?
Hope all that makes sense! Theres only some much googling you can do before your brain goes mush. Things also get very hardware specific and my situation is compounded by having a CGNAT internet provider (EE) and having 4G home internet!
