Assuming that you have created the database and changed the configuration to active, it should just work.
You will need to post more details to how you have Zeroshell configured if you would like more help from the people in the forum. Give us things like what device you are instaling it on and how you are booting the Zeroshell install. For instance, is this a CDROM boot on standalone computer?
Also, how did you setup the configuration database, default gateway, IP addresses, etc.
