1:1 Nat using ESXi VM's

I seem to be having a problem getting 1:1 nat working for my virtual machines,
I have a block of 5 static's (X.X.X.49 / 29) of which I am trying to use one of them specifically for a VM that is working as my web-server, However when I check my outgoing IP from the web-server VM, it's using the same IP address as the rest of the machines on my LAN.

I've triple checked my settings after following the recommendations from:
wiki.untangle.com/index.php/1:1_NAT
and
forums.untangle.com/networking/4280-one-one-nat.html
which were both very simple, and straightforward and sounded like they should work for this.

Do I need to create a NAT rule for the ESXi host itself instead of the individual VM's?

A few notes, that didn't make it to my quick diagram.

• The default External IP is .49 / 29
• The additional .50,.51.52.53 are added as IP Address Alias for the external interface
• For the 2 port forwards the content between the ** are just the identifying names (are these rules conflicting with eachother? does it matter?)
• I will likely be using another 1:1 nat rule for the test VM in the near future, this should just use the same settings as the current one I'm having trouble with correct?
