I appreciate the help. I use a modem connected to linksys gateway with dhcp turned off. That runs into one network card on the linuxmce hybrid. An ethernet switch is connected to the second network card. All other computers are connected to the switch. I turned everything on in the following sequence: Linksys, LinuxMCE, router and then other computers on the network. All computers on the network have 169.254.181.xxx addresses. As far as which network connector is external or internal, what would determine which would be which.
