what is "use wan uplink mode " in wan settings ?

HI Mr.X ,
i didn't work with this type of routers before but from router datasheet i can see the following :
this option used when you use NBN ISP for other type of internet connection of example PPPOE which is require Username/Password , no need to tick this option .

check page number ( 22 to 25) from datasheet .

my guess is it expects to be chained to a separate router. this button probably disables all NAT features. you would configure the router with a simple default route with the IP of the parent router or the router might use DHCP on the uplink port.
