    BEST FIREWALL For RED HAT LINUX 8

    I am new to Linux. I am using Red Hat Linux 8.0 Pro. They say that it comes with a firewall. How good is this firewall? Is it something like Windows XP version of firewall? Do I need to get another firewall like Zone Alarm ? If I need to get one, which one do you recommend for Linux?

    Thank you for answering my question.

    I am not a linux guru, nor do I claim to be. However, I do know Linux comes with a built in firewall called Ipchains (and in newer versions, IPTables, a more powerful firewall).

    Good luck!

    The more important question here is, "Which firewall best suits my needs?" Sit down and determine what your firewall needs to do then decide which firewalls perform the tasks well. This will save you some time and sanity - trust me.

    The canned firewall that comes with RedHat 8 will work fine for most home users. It uses, as you already know, IPTABLES, which can be manipulated either command line or through the GUI that comes with KDE/GNOME, etc.

    If you are unfamiliar with firewall configuration, I'd suggest that you read up on IPTABLES and how it works *before* you depend on it securing your network. One of my *favorite* things to find is a misconfigured firewall.

    Anyway, before I go off on an unsolicited rant go ahead and search the forums here on how IPTABLES works and how to configure IPTABLES. There are plenty of talented folks here who have addressed this in the past and I know that it will help you too.

    Good luck!

    IPchains no longer exists it was replaced by IPtables. IPtables is a great firewall, but a nightmare to configure. Look at Iptables configuration scritps like gSheild. If you can wait I will be writeing up a tut on this tonight and tomarrow (hope ot have it up saterday...I am a slow writer.)

    If your not running any kinds of servers, you be good just using the security level configuration tool. Set it to high (that is the default). You should be rather secure as it would appear that no open ports are available from the outside. Use nmap to scan your ip address. If you decide to run a server, you can always customize the security level, to allow incoming server requests.


    Thanks,

    - Iptables is really a very good packet filter firewall, and you will find in general that 'real' packet filtering firewalls
    are complicated to configure, this is true even on the most advanced commercial firewalls like those of Checkpoint.
    So with this I say it behooves you to learn Iptables well, because it is a quite capable firewall and greatly surpases
    the abilities of tools like Black Ice and Zone Alarm and the other laundry list of sub-par firewalls for Windows/Mac,
    and is essentially an Industry grade packet filtering firewall.

    - Syntactically, ipfw that comes with OpenBSD and FreeBSD is a fair bit easier as the rule sets are essentially plain
    english (e.g {$fwcmd} allow tcp from any in 192.168.1.0/24 to 192.168.2.1 on 25 established ), etc. This option
    does not help you unless A) you have a spare box that you can load OpenBSB or FreeBSD on, or B) you decide
    to use either FreeBSD or OpenBSD on your workstation.

    - If you can at all afford it ( a 486 with a 10/100 NIC can make a good firewall using iptables/ipfw) you really should
    try to place your firewall between your network/workstation and the internet at a minimum.
