Proxmox Networking Setup

Good morning all,

I am quite new to proxmox, and quite uneducated in server network set-ups. I have a host server which has Proxmox installed. It has 2 Ipv4 address pointed to it. The setup that i need is for one of the IP address to point to a VM which will contain pfSense or ngix.

I cant seem to get my head around the network configs, ive tried pretty much everything i can find to no avail. I cannot get any VM, or container for that matter to access the internet.

I would not grovel for help if i hadn't tried everything in my arsenal. I've had to put my server into rescue mode so many times due to me messing with the /network/interfaces.

Any sort of help or guidance would be massively appreciated, if not rewarded. I am at a loss of where to go with this now.

Thanks, Scott
