Configure firewall/router on a virtual server with a single nic

Hello All,

Thanks in advance

I assume you have a real front-end modem/router device for internet connection, and you want some real client devices attached on a private LAN and pfSense is firewall/router between the 2. In that case, you have to have the front-end modem router ethernet cable plugged in to something, and the back-end LAN switch/device plugged in to something.
The somethings can be 2 real NICs on the real device that ultimately runs pfSense (inside a VM or whatever) or a VLAN switch attached to 1 real NIC.
If you only want pfSense to be in a VM, with all the back-end LAN clients being other things running in VMs on the hardware you have, then all the back-end devices can connected with pfSense LAN internally/virtually and the 1 real NIC connects out to the modem/router.

The easy simple solution is to jut buy another nic – they are not expensive unless you going for some quad port server nic..  Any ole 20$ desktop nic would get you working.
