A powerful and easy to use Proxy/Firewall for internet connection sharing. ComTun has many advanced features useful for both business and home use. With support for access control and banner blocking, you have ultimate control of your connection. A fully customizable firewall protects you from hackers, and works seamlessly with the proxy service. ComTun uses NAT to give your clients a transparent connection to the Internet, and can be used to configure your clients automatically (with DHCP). Traditional daemons can also be used, if necessary, but in most cases are only needed to supplement the NAT connection. System administrators concerned with sharing connections with certain services or to certain sites will find that ComTun offers almost unlimited control over the client connection. User and group permissions can be used to restrict access to web sites, requiring a login before pages may be viewed. With remote administration, administrators can control ComTun from any computer.
