eth0 External Static 192.168.100.2
eth1 LAN Static 192.168.1.1

eth0 connects to my ADSL2+ modem with a static IP. The modem's DHCP is set to 192.168.100.100-199.
eth1 provides DHCP to my LAN

The nVidia is the NIC on the motherboard, it's the one not detected by ClearOS 7. This is an old Compaq presario CQ3000.

I appreciate that it's not that difficult, once the procedure is documented, to rebuild it after updates. The issue is that if I'm away then nobody else in the house knows anything about how to do it, so stability is very important. I don't want to have to drive 5 1/2 hours home from the snow next August to fix the internet LOL

Also it's the external NIC because it's only 10/100 and that's what passes for high speed broadband in Australia, meaning it can't be fixed from outside. The other NIC is gigabit, so it's better for the LAN.

Hence ClearOS 6.9 was the easier path.
