Where can I learn more about firewall configurations?

Will this be a topic/subject in the N+?

Firewall configurations? Do you mean like corporate firewalls? I dont recall seeing "too" much of this in my N+ books but I would still say its something you should know about. My company uses FortiNet and ive learned just by watching it be worked on.

 

I was just meaning personal firewalls, I'd like to know more about configuring ports and access protocols that sort of thing.

 

...don't know of anything off the top of my head, but most of the firewalls i've set up have a lot of handy tips when you loginto to the firewall itself - such as "standard ports" and what traffic they are used for etc...they usually have direct links to their manufacturers website that give more detail on how to configure....if you can't see it on the firewall it usually comes with the installation software CD for it...

...for anything I don't know of and get fed up of searching for, I just experiment!

Also, for a basic guide, you could always look at this...

and this for basics on port forwarding:

...or go to a website like Linksys, netgear or CISCO and download the manual for one of their firewalls...


...and this watchguard link may be quite handy:

Thanks for the links very helpful indeed rep given

 

How should you configure a firewall? Lock everything down, and open up only what is required. Simple as that.

 

Too right!

 

GBL, I find this guide on firewalls pretty informative. Someone posted it on another forum and I found it pretty good guide, helped me quite a few times.

 

You could play with your windows firewall on your o/s, although it's not exactly the best.

Deny everything as already mentioned and then start to open ports to allow specific applications to communicate. If you have a lab setup you could even start to add some ip restrictions to the rules.
