Install of web pack with ssl fails to allocate IP and cert

When trying to allocate IP addresses and to the certificate for each of the servers in a web pack it fails to allocate the address to the masters and slaves. It seems that it is trying to allocate to the "pack" node itself instead of the individual servers. Maybe there's a better way to do this using the contexts properly but the following seems to make it work.
