'this little GUI' ? which little GUI is that? All those firewall
GUI's do is tweak preconfigured iptable scripts which implement the
actual firewalling in the kernel. The problem is, most of the GUI's
are quite limited as to what they can and can't do, whereas iptables is
vmware has two basic network modes, 'bridged' and 'NAT'. With NAT,
the vm's are running on their own 'private' network, while with bridged,
the VM's addresses are seen as outside systems. You would need to
configure the host's firewalls to allow NFS (and probably RPC and a
bunch more) from either the private network or the specific IP(s) being
used by the bridged adapters.
