    A question for those of you who have used IPCOP.

    I'm playing around with this with a view to implementing it at work, and whilst I can get it to work hapilly at home on an ADSL line using a simple RED and GREEN NIC setup I have a problem at work.

    The problem is that our Internet connection goes through a Router / Firewall / Webfilter that I have no control over, when it went in it basically got assigned an internal IP address. Now, Its IP Address is on the same network as the rest of the internal LAN, but I obviously want to stick the IPCOP box between it and our LAN, just so that I can do some monitoring of my own.

    So, is it possible to set IPCOP's RED and GREEN interfaces to be on the same network? or am I going to have to get the ISP to give my 'Magic Box' as they so nicely call it, a new 'internal address' on a different subnet?

    Any suggestions are appreciated.

    can you re-configure the ip address, rather than have one that was assigned to you.

    what are you using ipcop for is because you have bad packets?:blink

    Simon - did you use the probe to detect your nic card?


    did the screen show this:-


    If you are using a modem, on the Network Configuration page, with GREEN (RED is modem/ISDN) highlighted.

    No, unfortunately not without asking the ISP to do it for me, and since I only want to test the solution I don't want them involved at this stage.

    It will be used with a few addons for webfiltering and as a cache so that I don't have to rely on the LEA. Also I may want to set up a DMZ for webservers.

    Yes, I have disabled the ISDN elemet of it. Both the Red and the Green NICs were discovered.

    What about port forwarding page?

    IP source & network box:blink

    This is the field that controls external access - if you leave it BLANK, your port forward will be open to ALL INTERNET ADDRESSES. Alternatively if you put an address or network in there, it will be restricted to that network or internet address.
    :biggrin


    Once this is setup in port forwarding you can have more than one external address. If you wish to add another external address, click the green cross next to the entry, the entry screen at the top of the page will change (it will load values from the port forward) and allow you to enter an external ip address or network.

    Well I've only been using it since Friday when I got it up and running here at the house, simple red and green interfaces.

    I haven't used it so all this red and green malarky is confusing but as it's a firewall, well it needs to be between your local network and the Internet gateway. One NIC is configured in a subnet which matches your Internet gateway (external) the other has an IP address which is in your (local) LAN subnet.

    If it's just being used as a caching/proxy server you can probably get away with one NIC.
