Need someone to help me find a good url and to decipher some of the missing information in almost every search result I can find on how to set up pfsense as the main firewall, for esx and vms behind it on one single server. I have found countless links but all seems to be for their own unique uses or have missing details which never make sense.
I get how the idea works.
I get that you set up a pfsense firewall on the public side, then put your vms on the private side.
What I don't get which is never clear is how to set up the ESXi interfaces for this to work.
Some people talk about using no NICs, some say use a NIC, some say make a fake MAC, some say otherwise, it's just nonsense.
What I need to know are things such as;
The machine has two NICs and I could create VLANS but I want the simplest possible setup.
Obviously, one NIC is used for the public side.
But, the second NIC for LAN side, should it be in the main Networking configuration or adding a second one?
And should it use the real physical NIC of the server for the LAN side or should it have no NIC assigned and how?
Once this is set up, I need to change the admin interface of ESXi to be on the LAN side, preventing public access.
I fully understand that if I lose access to pfsense, I lose access to everything and other such issues. I do have IP KVM access in case anything goes really bad.
I'm sure this won't be that complicated once I can talk with someone who understands this so am hoping to find a solution on this site.
