A member server is just a machine which is joined to the domain.  If you 
do a NET ADS JOIN on a linux workstation, that is a member "server".  If 
you want this machine to act as an authentication server for other 
machines on the domain, what you want is a domain controller.  If you just 
want it to be a file server and to authenticate SMB users connecting to 
file shares, a member server is just fine.

As far as the IP/name resolution issue, if you only need samba to run on 
the public interface, you can add something like this to your smb.conf:

         bind interfaces only = yes
         interfaces = 192.168.1.1

interfaces = accepts either IP address or interface names.

However, if you want to participate in a domain on the public network, but 
want to act as an authentication server, DNS server, fileserver for 
clients on the private network, things are going to get much more 
complicated.
