General Questions

Hi to everyone....
I've done an entire virtual infrastructure, for testing VMware View service over a satellite internet connection.
I have a phisical machine wich runs CentOS 6.2 which has two network adapters (eth0 is on the hom LAN, and eth1 has a pubblic IP addres), on wich I have installed Vmware Workstation 8, on the workstation there is an host ESXI.
Over the host ESXi there are a lot of VM that I needed for the infrastructure of Vmware View.
Everyone of this VM has an IP like 192.168.x.x, and for completing this Home LAN infrastructure, I would like to create a firewall and a router (pfsense) so I can access this infrastructure from the Web, using lastone pubblic IP address i have.
I hope i've explained well the infrastructure, but i come to the question...
How to set uo the Nic for the Pfsense? How many virtual Nic i have to give to it's VM? Which one I've to NAT and which one i have to bridge, and on which connection or network?
I was forgetting....the networking of the WOrkstation is obviusly bridged over the eth0 (over the home LAN)....
Thanks to every one who will answer me...
