This is the first time I've set up an ESXi 5.5 server on a DMZ, and I
want to verify what my networking configuration should be. Here's what
I currently have - 5.5 host has 2 NICs in a standard vSwitch for
management network, set as active (NIC #1) /standby (NIC #2). All is
well, and I am communicating with the server using the vSphere fat
client well,

 All my VMs will be P2Ved from the existing physical boxes. All
currently have 2 NICs - one for the DMZ (external facing) side, one
for the LAN (internal facing) side. Pretty standard so far. So what I
think I need is:

 1 standard vSwitch, port group named DMZ, 1 server NIC (#3) assigned
to it. VLAN = xxx (I will have my networking guys create this new
VLAN)

1 standard vSwitch, port group named InternalLAN, 1 server NIC (#4)
assigned to it. VLAN = yyy (I will have my networking guys create this
new VLAN)

There is a Checkpoint firewall protecting the DMZ. It has 1 interface
for the outside world, 1 for the trusted LAN. And 2 other interfaces,
for use by my ESXi host - 1 interface for the DMZ, 1 for the 2nd NIC
of the VMs.

So:

if I P2V my physical DMZ hosts; assign the proper portgroup to each
virtual NIC in the VM; and plug the cable from each server NIC into
the correct port on the firewall, everything should be good.

Traffic will come in from the Internet via the public port on the
firewall; go through the DMZ interface of the firewall to the DMZ
interface of the VM; if the VM needs info from the trusted LAN, it
will request it via the internal LAN interface of the VM, which sends
it through the firewall to the proper host on the trusted LAN. and
vice versa, for the returned traffic. (I don't have anything to do
with the configuration of the Checkpoint, or any physical switches)

Yes? Am I missing something major here? As long as I keep my server
NICs going to different interfaces on the firewall (properly VLAN
tagged), and have my VMs NICs going to the right port group, I should
be good.

I hope I explained that clearly enough. Feel free to question me for
further details, of course.

Thanks
