Firewall & Security - Softperfect
Softperfect - is a free network firewall
designed to protect your PC against attacks from the Internet or
via a local area network. SoftPerfect Personal Firewall offers
customizable security using user-defined rules for packet
filtering. It works at a low level and also allows you to create
rules based on non-IP protocols such as ARP.
The SoftPerfect Personal Firewall supports multiple network
adapter configurations. This allows you to apply a rule, for
example, for just a modem connection or you could apply separate
rules for each system interface. With a flexible filtering
system, trusted MAC address checking feature and separate
network adapter configuration you can even use it on a router or
a server.
