|
# VMware ESXi
|
|
|
|
This setup is running on the free version of ESXi 7.0 U3<br>
|
|
|
|
#### Network setup
|
|
|
|
Two physical network cards - NICs
|
|
|
|
* the default `vSwitch0` will be used for LAN side
|
|
* create new virtual switch - `vSwitch1-WAN`
|
|
* create new port group - `WAN Network`, assign to it `vSwitch1-WAN`
|
|
|
|
#### Virtual machine creation
|
|
|
|
* Guest OS family - Other
|
|
* Guest OS version - FreeBSD 13 or later versions (64-bit)
|
|
* CPU - 2 cores
|
|
* RAM - 2GB, for basic functionality, later can assign more
|
|
* SCSI Controller 0 - LSI Logic SAS
|
|
* VM Options > Boot Options > Firmware - EFI
|
|
|
|
Afterwards, edit the VM, add network adapter connected to `WAN Network`
|
|
|

[Download](https://opnsense.org/download/) the latest opnsense - amd64, dvd,
|
|
extract iso, upload to ESXi datastore,

|
Disconnect your current router and plug stuff in to the ESXi host.
|
|
|
|
* let it boot up
|
|
* login `root/opnsense`
|
|
* set interfaces, in ESXi VM overview you can see networks and MAC addresses
|
|
* set IPs, wan is usually left alone with dhcp,<br>
|
|
static ip for LAN and enable dhcp server running and give it range
|
|
* afterwards you should be able to access web gui
|
|
* log out
|
|
