What are some cheap packet screening tools?

The Texas A&M University security tools include software for implementing screening routers. Karlbridge is a PC-based screening router kit available from ftp://ftp.net.ohio-state.edu/pub/kbridge/.

There are numerous kernel-level packet screens, including ipf, ipfw, ipchains, pf, and ipfwadm. Typically, these are included in various free Unix implementations, such as FreeBSD, OpenBSD, NetBSD, and Linux. You might also find these tools available in your commercial Unix implementation.

If you're willing to get your hands a little dirty, it's completely possible to build a secure and fully functional firewall for the price of hardware and some of your time.
