Kind of a continuation of this thread:

Basically what I'm trying to do is route all my internet traffic for my Host OS and VM's through my PFsense VM so that I can manage a centralised firewall and setup appropriate port forwarding as needed from my public IP addresses.

I have a hosted Windows 2012 dedicated server with 4x public IPv4's allocated to it. e.g:

101.0.102.100/29 --|--> WIN2012_HOST
101.0.102.101/29 --|
101.0.102.102/29 --|
101.0.102.103/29 --|

And a gateway of 101.0.102.199.

On the server I'm running VMware Workstation with a bunch of guest VM's including PFSense.

WIN2012_HOST
   |- PFSense_VM
   |- Guest1_VM
   |- Guest2_VM
   |- Guest3_VM
   |- Guest4_VM

I setup the PFsense VM with two network interfaces; 1xWAN (Bridged with physical host interface) and 1xLAN (Virtual host-only interface) so now I have a virtual NAT'd network for my VM's.

In PFSense; I gave the WAN adapter the second spare public IP and setup the remaining 2 as 'Virtual IP's. I then enabled DHCP and in VMware added the virtual host-only interface to my other VM's to get them on the private network.

101.0.102.100/29 ----> WIN2012_HOST
101.0.102.101/29 --|-->  PFSense_VM - 192.168.1.1/24
101.0.102.102/29 --|         |- Guest1_VM   - 192.168.1.2/24
101.0.102.103/29 --|         |- Guest2_VM   - 192.168.1.3/24
                                       |- Guest3_VM   - 192.168.1.4/24
                                       |- Guest4_VM   - 192.168.1.5/24

What I really want however is to end up with this:
101.0.102.100/29 --|--> PFSense_VM            - 192.168.1.1/24
101.0.102.101/29 --|       |- WIN2012_HOST  - 192.168.1.2/24
101.0.102.102/29 --|       |- Guest1_VM         - 192.168.1.3/24
101.0.102.103/29 --|       |- Guest2_VM         - 192.168.1.4/24
                                     |- Guest3_VM         - 192.168.1.5/24
                                     |- Guest4_VM         - 192.168.1.6/24

I found a post here which is basically what I'm trying to do however it's a bit confusing so would appreciate if someone could please walk me through getting my Host OS onto my private network and routing its traffic through my PFSense VM too.

I haven't played around too much with it as I'm working over RDP any don't want to end up killing my connection however I do have KVM access if all goes too wrong.
