It looks like cloudmin installation creates a new virtual eth interface called peth. Even after changing to eth0, it reverts back to peth and i lose connection to internet on this machine.
I have a virtualmin gpl running on machine 2 as a backup for virtualmin pro server on machine 1.
on the gpl machine, i wanted to try cloudmin. but after installing, i am unable to connect to internet.
both servers are not behind any firewall/router. they are directly connected to the cable modem through a gigabit switch.
