Whether you use it to build a firewall, or to secure you application from network harassment, SocketBlock can provide an application with the ultimate in security, and requires no driver installation, almost no knowledge of networks, and uses minimal resources.

The basic procedure for creating a packet filter is simple using SocketBlock: choose a name, whether all traffic should be blocked or not as the default behavior, the IP address to bind to, and then use these with the CreateFilter method. Next, add as many filter rules as you wish by defining which protocols to block (TCP/UDP/ICMP), the packets direction (packets entering or leaving the machine), the source and destination IP addresses, subnets, and ports, and then use the AddFilterRule method. Once all of the desired rules have been added, simply use the ActivateFilter method to activate the packet filter. SocketBlock also provides many additional features, such as access to low level protocol statistics, strong host checks (spoofing), fragmented packet checks, and more. SocketBlock can be used by environments that support events (ConnectionPoints), as well as those that do not (such as ASP) by allowing an application to use it in polling mode.
