BullDog is a powerful but lightweight firewall for heavy use systems. With many features, this firewall can be used by anyone who wants to protect his/her systems.
This system allows dynamic and static rules sets for maximum protection and has several advance features.
This firewall will work for the hobbyist or a military base. Generation 7 is a complete rewrite and redesign from scratch. Generations 2 to 6 died in agony of failures in the testing and development of this version.
Be prepared to spend some time setting this up. If you are looking for a "quick fix", then you are on the wrong site. BullDog is NOT a quick fix, but rather one step in a complete security policy.
Its is covered by the GPL and is FREE and always will be. The developer encourage and welcome anyone who wants to port and/or provide ideas/code to better this software.
I would like to see this software developed into a new breed of firewall that provides the best of security with ease of use.
