Mabry's Firewall/X OCX & COM objects make it easy to write custom  
firewall/proxy servers. FirewallX 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 implement client access filters, redirect 
clients requests, log all traffic, and relay requests to 'hidden'  
hosts. Additionally you can 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'll want to use Firewall/X to create 
exactly what you need. Like all of Mabry's Internet controls,      
FirewallX comes in both ActiveX Control and COM Object forms to make
it convenient for you to integrate it into nearly any Windows      
programming environment.
