Firewall with features of a Sidewinder firewall?

Hi fellas and gals,

I am new to this foram, and to linux. I have read some of the threads and am glad to see this forum is here.

I have a question of a setup I am going to be doing in the near future.

I want to use a box with Mandriva 10.1 linux on my home network as the firewall and service delivery point for my network. behind this firewall I want to have my wifi AP and other wired systems.

Now for the question, I want the a firewall app loaded on my linux system that is similar to the Sidewinder firewall(if any are familiar with this) Sidewinder firewalls have rules allowing access source IPs/subnets to dest IPs/subnets based on ports(ie, telnet, 80, 25, 22, etc). Thus it is very granular.

Another feature is the logging. I want logging of all allwoed access and denied access in an audit log file, that will keep for a certain amount of days and then delete itself. Preferrably I want to be able set the log level to log more or less detailed items.

I have heard about IPFW as a firewall solution. I have read quite a bit about IPtables from here on this forum.

Which would by my best solution for what I want?

btw, i also want to use this system for other minor things like seeding torrents using bittorrent and other stuff, but thats a side item.

Thanks for all your help.

IPtables is always the best since it forces you to learn and understand how packets come into the system, navigate through the custom rules you specify and then get dropped/logged/accepted.

im new to the linux security scene also, but from what i understand:
Shorewall, like any other "firewall" is just a GUI that allows you to easily work with iptable scripts. the shorewall program itself dosent actually inspect the packets, it just assigns rules to iptables that you set in the pretty GUI. btw, firestarter is a great user friendly firewall. i strongly encourage you to look at some documentation on how to secure a mandrake system (*giggles*) , just installing a firewall and setting a few iptable scripts does NOT make your system as secure as it needs to be.

just to clear things up a little:

the linux firewall code is called Netfilter...

the tool to configure Netfilter is called iptables...

programs such as Firestarter, Shorewall, etc. are simply front-ends to iptables... and BTW, front-ends don't necessarily have to be GUIs (they can be text-based)...

so to setup your linux firewall you can choose one of the several iptables front-ends that are floating around out there, or you can use iptables directly...

here's a decent iptables tutorial:


you can find links to lots of example scripts and other stuff here:

just my two cents...

PS: IPFW isn't a linux thing... it's a FreeBSD thing... ;-)
