I thought this might of interest, so posting here. (I'm not associated with these folks at all and am not using the product, BTW.)

Mabry's new Firewall/X OCX & COM objects make it easy to write custom
firewall/proxy servers.  Firewall/X provides direct support for the standard
proxy/firewall types: Telnet, FTP, Finger/Whois, Socks, Pipe, and HTTP.
Additionally Firewall/X makes it easy to define your own firewall types.

Using Firewall/X you can easily implement client access filters, redirect
client's requests, log all traffic, and relay requests to 'hidden' hosts.
Additionally you can easily provide for remote administration by implementing
custom commands.  If you've ever been frustrated by the configuration problems
and limitations of the various firewall/proxy servers on the market then you can
easily create exactly what you need using, for instance, Visual Basic or VC++
and Firewall/X.

Like all of Mabry's new internet controls Firewall/X comes in both ActiveX
Control and COM Object versions to make it easy for you to integrate it into
nearly any Windows programming environment.

See www.mabry.com for complete documentation and fully functional non
time-limited demo control and sample programs.
