How many physical NICs for the ESXi configuration?
I'm looking into setting up ESXi at home for a test virtual domain. I have almost all the required ESXi-compliant hardware but need to know how many physical NICs I'll need. Here's the scenario:
My home physical LAN is 192.168.10.0 / 24
I'd like to have the virtual LAN as 10.10.10.0 / 24 but still have access to the internet. I've been recommended to use something like IPCop installed in a guest VM. I realise it would need two IP addresses, one on 192.168.10.0 / 24 and the other on 10.10.10.0 / 24. Does that mean I would need two physical NICs?
An extension would be if I added a further virtual domain (to simulate another company's network on another continent that the first company's domain might "take over"). That network's address might be 172.16.0.0 / 24, again, behind it's own IPCop virtual firewall. Would I need further physical NICs for this scenario (upto four in total) or could the whole thing run using a single NIC?
I stress that I wouldn't need extra NICs for bandwidth as it's only a test setup at home. Needless to say, I've never played around with ESXi so want to get my head around what hardware I'll need. I've thought about other virtualisation solutions but ESXi seems to be my preferred one.
Thanks in advance.
