So I am doing an install of MiCollab, vMCD, and a vMBG... pretty simple, until the customer decided that they want to do their "DMZ" more like a 1:1 NAT on a separate virtual NIC for the MBG and MiCollab servers.
Essentially on the LAN NIC of those servers is a 192.168.200.X IP address in the voice VLAN, and on the second WAN NIC they have a 1:1 "DMZ" NAT with addresses of 172.16.20.X, where each IP address internally is mapped 1:1 to a public IP address
Now I know I can make this work with the MBG using a custom configuration, but how does this work for AWC on the MiCollab since it needs 2 public IP addresses, one that is resolvable, and a second one for the AWC that is just a public IP address. Would I need two 172.16.20.X IP's mapped independently to two public IP's, or could I use one 172.16.20.X IP address and have both public IP's mapped to that one internal IP? I am guessing I need two internal and two public, but I have never done this kind of a configuration before.
Would have been so much simpler if they just would have put them in a real DMZ, or allowed the public IP's to come directly into the WAN NIC's of the VM's (my preferred way).
Thoughts? Is this going to work, or am I just asking for issues with this setup?
