    Configure smoothwall to just allow http, https and ftp connections

    I just installed smoothwall 3.0 on my ESX server. I have therefore a completely virtualized network on which I installed smoothwall that bridge between my ESX server and my real network. But I want my smoothwall to be configured so that all incoming and outgoing flow is blocked except for a computer on http, https and ftp. I can not so I leave it to you.

    Details:
    red (DHCP) + green (static IP)

    This virtualization of the firewall is designed to assess the feasibility? I suppose you have quite understood that instead of an effective firewall that is surely not to be a VM. What is your understanding of this very important issue? How many physical interfaces to ESX server you have?

    Re: Configure smoothwall to just allow http, https and ftp connections

    Let me explain my situation more clearly:
    I currently have a network set up, which I connected my ESX server (2 network interfaces) on which I have my virtualized server 2003 that serves as my domain controller and a server 2008 that serves as my database and WSUS.

    Then I have added a client and a smoothwall which serves as a bridge between my ESX server (my virtual part) and my real network is in place. However, I can not set the smoothwall to block all incoming and outgoing flows that is necessary to save my windows 2008 server to update wsus. Knowing that to have access to internet I must go by my real network which has a proxy.

    - What is the background: Pro or Custom?
    - Do you understand what I write about virtualization?
    - Do you know ESX includes "virtual switch"?
    - How are the network interfaces configured in each VM?

    I repeat often: A problem well stated is half solved! Obviously, you specify the "bricks". But where are the cables / connections? (these virtual switches!)

    This establishment is in a professional context.

    I said:
    I have a network to which I added an ESX server on which I have 2 servers windows virtualized (with fixed IP), the client XP (DHCP) and smoothwall in a green (static IP) + red (DHCP).
    _Green is connected to a virtual switch that connects my servers and my virtual clients.
    _RED is connected to another virtual switch that achieves the real network.

    Smoothwall serves as a bridge between the 2 filter switch to allow my virtual network to access the Internet via the real network to ensure the wsus update.

    Re: Configure smoothwall to just allow http, https and ftp connections

    Me in pro, I do not virtualize the firewall.

    Sometimes I do (for testing, should make this clear?). But as I always start by making a clear pattern on a sheet (with everything you need: ip address, switch, flow rule allowed), I do not deserve to pass these tests.

    There are many things that seem so uncertain:
    - "Fully virtualized" I prefer fully operational
    - "ESX server" vs. "real network": a pattern?,
    - "All incoming and outgoing flow is blocked": this is not what should be the basis? So this is not a goal!,
    - "My real network which has a proxy: it does not matter
    - Several answers but still no pattern ...
