I've 3 same interfaces on my asg box which are e1000 devices...
and I see only 2 of then into astaro UI (attached snapshot) whereas there is 3 when doing:
asg:/root # ifconfig -a | grep eth
eth0 Link encap:Ethernet HWaddr 08:00:27:BF:78:68
eth1 Link encap:Ethernet HWaddr 08:00:27:A4[:D]9:10
eth2 Link encap:Ethernet HWaddr 08:00:27:12:C5:26
asg:/root #
thx
edit1: I did removed my PPPOE interface then rebooted and all the 3 interfaces appeared... really strange
