Multiple Networks on Proxmox

[sandesh]

Hi,

I would like to configure multiple networks on my proxmox server which is having 3 Ethernet cards, and my networks are like 192.x.x.x 172.x.x.x and 10.x.x.x

So how should I host multiple containers with different network schemes,

Note:- I don't want to use KVM here.

Thanks in advance
Sandesh

a good point to start:
http://pve.proxmox.com/wiki/Network_Model

and on the console, get familiar with 'vzctl'. (see man vzctl)

Thanks Tom for the link.

I gone through the link, I have set bridge using proxmox web interface,
So vmbr1 --> eth1
vmbr2 --> eth2

I get stuck here for deciding what next step I need to follow after this, so that container 1 should have 10 subnet IP and it get routed from eth1 only.

Thanks,

When you create the container you can select the bridge to connect.

Network setup needs to be done inside the container, like you would do on a physical host (when you use bridged network).

Hey Dietmar, I have figured out this thing by some googling, Thanks for your reply too..

I have one question,
Which is the most secure or advisable way to have IP address in Bridging mode, means is this OK to have IP address assigned to Bridge or better to have IP to Network Card. I have gone through one post where one user says about to have IP address to NIC rather than to assign IP to bridge.

Also what to do if I have 3 different network on same HN, means what precautionary measures to take so that there is no network collision between these networks.

Hi,
if you run in bridge-mode, than you have to assign a ip-address at the bridge and not at the nic. But this is not more ore less secure - its equal.
To take care, that your networks will be seperate all machines with more than one nic (host, or vm) must disable routing.

There is an additional option - do not assign an IP at all (only assign the IPs inside the guest)
