Proxmox VE network model
This section provides a high-level overview of the Proxmox VE network model. It covers subjects relevant to both Proxmox VE guests as well as hosts.
In Proxmox VE 4.0, two fundamental guest network configurations are supported:
- Bridged
- Masquerading with NAT
The following subsection contrasts these two configuration models and establishes effective, sensible use cases for each.
The remainder of the subsection addresses Proxmox VE host configuration concerns:
- Routed configuration
- VLAN support
- NIC bonding
Bridged configuration
Bridged networking connects a Proxmox VE guest to a network using the host's Ethernet adapter.
Visualizing bridged configuration
Virtual machines and containers with bridged connections behave precisely as if they're connected to the physical network. Indeed, each virtual server has a virtual NIC (or vNIC) that appears to the network with a discreet and unique MAC (media access control address) and IP address consistent with the physical network...
