networking concepts in Proxmox

[eka]

Hi,
Being new I need some help or pointers to understand the networking
concepts in Proxmox, for the server as well as for the guest.

Here is what I would like to set up:
- 3 guests A and B (Centos), C (Debian)
have their own IP address by which they are visible from the
internet.
- 2 guests D and E (Centos) are not visible from the internet.
The Debian guest C operates as their gateway.
C makes http(s) available by pound loadbalancer
and SSH by iptables port forwarding.

- The Debian C system needs also to conect to A and B to do backups.

So A, B and C are dual-homed. E and F only connect to the LAN

My question is how to set up the virtual LAN for all and the internet connection
on the 3 dual-homed guests.

Much of the documentaion I have seen explains the Debian interfaces file.
How do I translate that to Centos?

Thanks

My proxmox server is at a service providers site. I have no access to their firewall. Will have to find out if they can help with routing the external IPs.
