yes I am using single card.
one of my nic is burned and have not had time to replace it, everything was working fine until I hit save the network settings.
save in the database this way
eth0,10.1.1.199,255.255.255.0,10.1.1.253,10.1.1.253,10.1.1.55 | eth0: 1,192.168.80.1,255.255.255.0 |,,
the only way to return to work was correcting for
eth0,10.1.1.199,255.255.255.0,10.1.1.253,10.1.1.253,10.1.1.55 | eth0: 1,192.168.80.1,255.255.255.0
