    Hmmm some strange thing going on here.

    I've done the 'The Perfect Setup - Fedora Core 4' and installes 'ISPconfig' with no real problems.

    Now I would like to use the 'Linux Firewall' the one accessale with Webmin, and not the firewall from ISPconfig, as I need to use some 'custom' IPTABLES.

    When I dissable the ISPfirewall, and enable the 'Linux firewall' I see sometimes the following message in the main terminal popup..

    As soon as I get the message on the terminal, I can not access anything anymore with the network!

    Anyone here who can help fix this?

    That's the normal behaviour when iptables is activated. Nothing unusual here.

    Check your firewall rules - there must be one or more rules that locks you out.

    Thanks again for the info. I was not sure if this was normal or not.

    The server is now in a datacenter, and the only way of accessing it at the moment is it with SSH.

    As I really do not want to lock myself out, I will wait till my next trip over to the datacenter and fix the firewall rules (I'm now using the ISPconfig firewall)

    What I really want to do is close and open some (different) ports on the 8 IP's that I have.

    Now when I scan my IP's they all show the same open/closed ports.
    To bad ISPconfig will not let you set open/closed ports per IP.

    With IPtables I can do so with no problem.
