Deco M4 in DMZ of modem/router - firewall?
(apologies if this is answered elsewhere - I haven't found what I needed searching the forums)
my setup is modem/router -> Main Deco M4 -> switch -> XBOX, PC, NAS, Other Deco M4s
Currently I have my main M4 as an access point - but would like to use it in router mode.
However, when I enabled this, I was getting a Double NAT warning on my XBOX (which I think might impact online gaming)
My modem/router doesn't have a bridge mode - so the only solution I can think of is putting the M4 in the DMZ of the modem/router.
My question is - are there security risks because of this? Does the M4 have any firewall?
(my main concern is the NAS on the M4 network, since I like having this behind a firewall from the internet at large)
My networking knowledge is pretty basic - so I might be overlooking something simple here..
thanks for any feedback/suggestions!
