    Need Help using 2 firewalls - filter one through the other


    Hi.
    I have need to use two firewalls. I'd be using Windows firewall plus another such as Comodo (but undecided.. still testing firewalls) I want my third party firewall to filter all connections outbound and incoming from my Windows firewall as a last line of defense.

    How can I do this? Is there a hook, DLL library, registry hack or some feature of a third party firewall itself, etc to tell Windows to do this? How can I make the two work together like I need them to?

    Thanks.

    Welcome to the forum. What is the point of this if a firewall is any good there will be nothing for the second one to do it will just drag tjhe system down and achive nothing. Unless you have expert knowledge of ports, protocols etc you can end up in a mess

    What are you actually trying to do do you use a nat router as that will have a firewall as well so that's 3 firewalls. If you on firewall one block port 80 UDP, trip,telnet,ftp,etc then on the second router there is nothing to set this applies to all ports etc. If your looking to block malware then it can come in via any port that's open. You often don't know what ports dome software may need open in order to work take ftp what ports will it use in specific modes?

    I got away it with two firewalls back when using Windows 3.11 - Windows for Workgroups 3.11 -- I had a great time with Zone Alarm and Norton Firewall back then. If memory serves me, I would disable any-everyThing not related to firewall duties [such often came as Swiss Army Knives]; then would "dumb down" both firewalls enough to get them working together. Slowly I would fine-tune 'em until they would report inbound, outbound, what was passed, what was blocked -- I had a field day for months!
    However, you have Windows 8. You're still testing, experimenting with Comodo Firewall, correct? You desire to experiment, and have OS partition backups, perhaps you can accomplish TheGeekDualWall

    As far as getting firewall B to receive everything from firewall A -- I don't know how to do that; the best I was able to do with tinker with both firewalls and get 'em to communicate with me without crashing.
    Concerning Comodo Firewall, it can be somewhat assertive, almost aggressive, you have to really finetune CF to keep it from grabbing your computer by the neck.

    I can tell you i'm looking to block certain outbound connections. I am looking to block malware because to me, even something as normal as Microsoft update for instance is malware when it is unwanted and unneeded. Thats not what i'm trying to block but thats the example I am allowed to give you. Yes, I have a Nat firewall built into my modem/router, that I cannot configure or control so it's no good to me. I'm thinking at this point I should build my own hardware firewall an use that in conjunction with something like Comodo., if thats the only way around my problem.

    Thank you for your reply. I'll have to keep plugging away at it. Like I said, go to a homemade hardware based, software controlled firewall that I can trust for complete control.. something where the code is open source so that lets comodo out.
