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

Which version of proxmox are you running? Did you check out the webinterface of it? You can setup bridges and bondes within so this route might get you further.

As I unreval you want pfSense to be the gateway for all other vms. So create a bridge with say eth1 and the tap device of the pfSense instance. Then create a nother fake eth3 device and bridge that with the second nic of pfSense instance and all other vms. Something like that.

I haven't used proxmox so I'd have to guess.

From their web page and not very well written.

Network Model

Proxmox VE uses a bridged networking model. Each host can have up to 4094 bridges. Bridges are like physical network switches implemented in software on the Proxmox VE host.

All VMs can share one bridge as if virtual network cables from each guest were all plugged into the same switch.

For connecting VMs to the outside world, bridges are attached to physical network cards assigned a TCP/IP configuration. For further flexibility, VLANs (IEEE 802.1q) and network bonding/aggregation are possible. In this way it is possible to build complex, flexible virtual networks. "

Looks like you kind of have a two step process. It is not a bad question at all. Maybe the proxmox forums would have a solid answer also.
