The linux firewall can only be installed via a kernel module or as part of the kernel itself. Look here for info on it, it is called ipchains: http://www.tldp.org/HOWTO/IPCHAINS-HOWTO.html
Where can get some free implementation information about VPN?
Perhapse GOOGLE might help
search for "Linux VPN" or something

ipchains has been superseded by iptables as of the 2.4 kernel.

Thanks CornedBee.
you can also program your own firewall application using netfilter hooks. it comes in handy if you want to implement an own analyzing/detection system. i think there was some phrack issue with an article about that. if not, use google.
