    What is the one most important thing for a newbie to know about rule based firewalls?

    I'm talking about specific knowledge,/facts not general principles like "deny everything untill you can figure out if it is necessary"

    Personally I think it's the concept of server and client (ephemeral) ports .

    I mean most people quickly figure out that TCP 80 is HTTP, but they have no clue how to configure the rule. Is port 80 remote or local? If remote, what port should be local?

    Hmm. I know you are joking, but assuming you are serious...

    1) I think my post was somewhat misintrepreted, due to the poor subject line. Actually I understand TCP/ICP and/or firewall rules at a beginner level but I was wondering if you wanted to teach someone how to use a rule based firewall, what are the miniumum amount of things they need to know.

    No offence, but pointing to a url with a 3-4 page jargon filled (to most people anyway) page wont work for most people

    2) There's no rule to say that newbies to Wilderssecurity cannot be experts. After all Wilderssecurity is not the centre of the security world. It provides a good place for beginners to learn from others (mostly people who are non-programmers but have slowly learnt bits and pieces of common security tips and understand threats to security on a high level)

    In fact, except for a few moderators etc. it would be laugable to call anyone here a "Security expert". Knowing how to use anti-virus, configure simple firewall rules , an expert one does not make.


    3) There are a lot of senior members who might be very knowledgable about security products by the virtue of trying almost everything, but they actually understand very little about the fundamental security principles and what the products they use really do, or how they do it.

    I fall into this category (in terms of knowledge not posts). To my non-geek friends, they are impressed when they know I use a firewall,I can talk about ports,tcp/icp ,cookies,SSL etc in general, but I'm very aware of how little I *actually* know and wouldnt pass myself off as an expert .

    This is not an attack on wildersecurity of course. But I wouldnt judge anyone has a "newbie" or "expert" solely based on the number of posts here.

    Hi JayK,

    I'm really sorry that you felt hurt !!!
    Sorry !!!
    It was not my intention that you felt that way.

    I myself am not the kind of person to call myself a "security expert".

    The "problem" with rule-based firewalls is that you indeed need a bit to learn about them.
    I thought that the links, which I posted, and the other posted links could help you in some way.
    Maybe I was indeed wrong here.

    Did you have a look at this link at the Wilders-site:
    http://www.wilders.org/firewalls.htm


    Maybe (just only a suggestion) it might be better to start all over again so we could leave this thread behind us?
    Only a suggestion: why not try to start a new thread with some specific questions about some rules?
    I give just only an idea: what kind of rule(s) would be the best for my email-program X with my firewall Y to be as secure as possible?
