Proxmox network model - coming from vmware environment

[francisco_reyes]

New to Proxmos and trying to understand the Proxmox network model.

I have previously used VMware for virtualization.
In VMware I would create a network and then assign NICs to a particular network.

When I create a container I can only use Bridged Mode, but if I do a VM I have Bridged mode and Nat mode.

Is bridged mode = giving VM access to network card in Proxmox so it can do it's own IP?
If I use Bridge Mode and gave an internal IP of 192.168.1.1 Will that exist only in the Proxmox host or would other users of the provider be able to see the traffic if they were in the same switch.
Switch 1 in Cloud provider
My host
Some other host

Would "Some other host" be able to see my traffic in 192.168.1.1?

In NAT mode is the traffic completely within my own host?

Any links explaining the Proxmox network model greatly appreciated.
Bought a book for proxmox and have found a couple of tutorials, but so far not making much sense of it.

Hi Francisco

.
When I create a container I can only use Bridged Mode, but if I do a VM I have Bridged mode and Nat mode.

If you use bridge mode, your VM or Container gets it own virtual network card (called tap) which is plugged in a virtual switch on your host ( vmbr0)
This virtual NIC gets its own mac address, and communicate with its mac adress on the local LAN, but you configure the IP adress on the guest.
It is quite easy to setup, and no require any extra configuration on the host.

Did you read https://pve.proxmox.com/wiki/Network_Model ?

Thanks for link. Does that mean if the cloud provider assigns an IP to my account I use the default bridged connection and assign the new IP to the VM?

How about NAT? A VM setup setup as NAT, what should I use as the gateway for the VM?

While digging on this also found that if one wanted a private network one could create a bridged NIC with no attachment to a physical NIC. Would be good to have that in the documentation too. I would suspect a common scenario for many would be one NIC for internal traffic and another for external.
