From the developer: "BrowseGate3 is a very powerful, yet low cost NAT/Proxy/Firewall system designed to work in any network environment from the 2 PC Home network right through to the the largest business network. It offers automatic on-demand Internet access to all network users via a single PC and can be used with modems, ISDN, ADSL, cable modems or other fixed connections. BrowseGate can be installed on any W95/98/ME/W2K or NT4 PC and does not require a dedicated machine for the smaller network installations. Under W2K and NT4 BrowseGate3 does of course run as a service. BrowseGate 3 offers full NAT connectivity, provides Port Address translation (PAT), and has a full caching web proxy for HTTP and HTTPS and also a SOCKS5 proxy. It even has it's own built-in caching DNS server, DHCP server, and fully configurable 'Stealth' firewall to protect your network from illegal intrusions. In addition to all the above, it offers has a powerful rules system, a Blacklist system for both web sites and user specified 'Words' and a web site limiting system."
