    use OpenBSD as a router and firewall

    Folks:
    I have an older IBM box that I have dumped 4 networks cards into the system. My main goal is run OpenBSD and turn the box into a VPN Gateway/Router/Firewall. I know this is not a ubuntu install, but since everyone is so helpful, i thought i would ask.

    Does anyone have procedures on how to configure a setup of this type or can someone point me in the right direction?

    Also, would it be easier for me to use Cent OS, Ubuntu or Fedora for this model?

    Thank you,
    E

    This looks nice. Have you personally played around with this product? If so, what do you like about it, and what don't you like about it. ]

    I usually work form the cisco cli, and only recentlly started to learn linux to help my career, and I read about linux firewalls, routers, and vpn gateways. Thought i might play around with them.

    Thanks.

    I find your question a bit confusing. You want OpenBSD (which is not Linux!), but then ask about CentOS,Ubuntu,Fedora.

    Apart from that it depends on what you exactly want to do.
    I prefer m0n0wall on some of my firewalls at work, because I like the GUI, it's fairly easy to set up, I like the fact that it uses FreeBSD, it works great on Soekris machines, and it does what i want and need. http://m0n0.ch/wall/
    And in m0n0wall I've configured a separate group for two other colleagues to login to the GUI interface just to be able to ping, and see the logfiles, and nothing more, just for troubleshooting, I think that's a cool feature to have build in.

    If you want more than m0n0wall offers, then take a look at pfSense : http://en.wikipedia.org/wiki/PfSense

    I've been using OpenBSD for my firewall/router for years.

    Love it!

    I didn't know that OpenBSD was not Linux. Is OpenBSD Unix then? If this is the case, how different are the commands? What are other version of Unix? Only version of Unix I knew of is Solaris, by SunMicrosystems, and i thought this was the only current Unix release in the wild; however, I just started learning about Linux and Unix, and currently run Fedora and Ubuntu. I found it easier to use Fedora for my Linux+ studies.

    Thank you for the links, and recommendation on software. I hope to try this product out this weekend. Currently I am just collecting input, which I can use to build an idea or model on paper, and then deploy in a test enviornment.

    Cheers!!!

    Is it preatty easy to configure? I am not looking at deploying IS-IS, or OSPF - just some static routes would be nice. Oh hey mate, does it support routing on a stick with vlan trunking?

    OpenBSD, just like FreeBSD and NetBSD is a Unix-alike just like Linux, except with a different code-base. Linux was written from scratch, after Linus Torvalds got frustrated about Minix.
    See here for more information about the background from BSD : http://en.wikipedia.org/wiki/BSD
    If this is the case, how different are the commands?
    I can give you some examples in commands between Linux and FreeBSD :
    In FreeBSD the command "free" doesn't exist.
    The sometimes very useful command "watch" in Linux, does exist in FreeBSD but does something different.
    But in general a lot is pretty much the same or alike.
    What are other version of Unix? Only version of Unix I knew of is Solaris, by SunMicrosystems, and i thought this was the only current Unix release in the wild; however, I just started learning about Linux and Unix, and currently run Fedora and Ubuntu. I found it easier to use Fedora for my Linux+ studies.
    There's Solaris, HP-UX, IBM's AIX, SCO (cough..) UNIX and perhaps more : http://en.wikipedia.org/wiki/Unix#Branding

    No problem, good luck! m0n0wall is fairly easy to set up, and you can (amongst others) choose between using only a hard disk, or only cdrom+floppy (no hard disk), or compact-flash only.
    Installing and configuring OpenBSD is really not that easy, and getting the default firewall software up and running takes some reading and/or research.
    Compared to that m0n0wall is a breeze.
