Here goes nothing.. On my boats LAN system I have two GW's. One over a WIFI connection (192.168.169.2) and one over a 4G connection (192.168.169.1) Now when I'm in a WIFI area, I make manual changes to every PC's NIC to use GW WIFI. When I'm not in a WIFI area, I make manual changes to every PC's NIC to use GW 4G. I've got a Raspberry Pi 2 in the LAN running some small script, and I guess that I could use this to setup some kind of DNS system. But will this work? IE. Will it be able to detect the WIFI and/or 4G connection and "push" the GW to the other PC's in the LAN? Any suggestions are welcome. PS: When both GW's are available I would like the system to use the WIFI GW, and.... All other PC's in the LAN are Windows systems.
