well first you need to explain how works
your network (which range of ip, your gateway, your subnet)
what is the os which handle vmware (on your host supervisor)
after that you will set the IPs settings in the console of smeserver like you could do with a real computer, it is the magic of bridged network in virtualisation, whatever the virtualisation platform chosen you will find the same principles.
I would suggest that you first play with smeserver in a real environment first, then you can envisage to try the virtual environment....of course I have no idea of your skill with linux or sme, sorry for my impertinence.
