Hi,

FYI, the Deco M4 does not support DMZ yet, while it supports port forwarding. Regarding to the double NAT issue, you can setup the port forwarding for the Xbox.

M4 does have firewall, and cause the M4 connected to the modem/router, with double NAT existed, it will protect the whole network. 

May it help, good day.

Hi,

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!
