[datayoung]

I am setting up server at home and willing to move to datacenter
while setup process,ispconfig ask for IP address

1.Can I just use my network ipaddress instead of real ipaddress from datacenter assigned? then change it latter from remote after plugin rack cabinet?
and the way to change just change the /etc/network/interfece (ubuntu) or anywhere else to looking for it?

2.I have to LAN cards,Can I use eth0 for real IP and eth1 for my internal
so I don't have to change later ,then ISPConfig will using which one?

Whom who using server which 2 LAN cards as real hosting,may be great to advice me

If you want to change IP addresses later, have a look here: http://www.howtoforge.com/forums/showthread.php?t=2760

You can specify the IP addresses under Management -> Server -> Settings in the ISPConfig web interface.
