I would recommend you try with Linux instead. &nbsp;Windows is too closed source to be of any use to any programmers just starting out with this sort of thing.

Well wouldnt a basic version of a firewall just need to listen on selected ports and do nothing with the recieved data.<br />
There is a bit in the networking lib of .net that'll allow you to do this.

build a firewall, Links........

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
