If you decide to develop a Firewall for Linux, you will find a lot of information and source code, all free. However people interested in Firewall for Windows Platforms have a little more difficulty, not only for finding information, finding free source code is a task impossible!!.

So, I have decided to write this article that describes a simple method for developing Firewalls for Windows 2000/XP to help people interested in this subject.

Sweet man, thanx.

Excellent coder!

Should definatly come in handy for someone lookin to build their own protection for their win box, then relying on the close source altenatives!

Still....(get linux and learn iptables!! )

Thanks man Very good code for one of my projects.

how about an iptables for windows (opensource)

cya

nice !! thanx

thanks man, looks damn intresting and good

neat man tnx

nice idea

I tried all closed source apps. NONE of them worked well for me.

thank very much.

I need to modify the source so the firewallapp goes into trayicon instead of taking up a space on my taskbar.

good work.

it works very good

it blocked ports as it should

Mouse: can you post your version here?

Damn, nice. I've been looking for something like this for some time.

nice job thx man

here

I just do much and is done for now.

will look into getting to log attacks.

hey thanx man,
a question came to my mind:
whats the difference between a hardware firewall and a software one ?

what is this written in , is it vb or c++ or different

hardware = a bitch to open ports if you forget your pass =/

its in Visual C++ i believe

thx
now everyone can start writing his own Firewall

there is another similar firewall at http://www.codeproject.com/internet/smfirewall.asp

Anyone willing to make it CLI only? Looking at the code shouldn't be so hard...calling int CPacketFilter::AddFilter(char *localInterfaceIp, int direction, char *srcIp, char *srcMask, char *dstIp, char *dstMask, int srcPort, int dstPort, int protocol). I'm too lazy to do it by myself
