I have two general questions just to be sure my thinking is correct.
If I want Nethserver to sit behind my ISP router and all traffic to pass through it, in and out, I need a Ethernet port set to RED and configured to use the ISP router as it's gateway and DNS, and I need a second port set to GREEN for all other devices on my LAN and configured such that they use this port as their gateway and DNS and Nethserver will handle to routing. Is this correct ?
In order to stop WiFi traffic bypassing the Nethserver by connecting to the ISP router directly, I have disabled WiFi on this router and set up a second router for WiFi. Can I set this up as a second GREEN network, add it to a 3rd port on the Nethserver and allow routing between the two GREEN LAN's so laptops can access shared drives on a NAS box on the wired LAN and computers on the wired LAN can access a network printer that is WiFi because where it sits there is no Ethernet port.
