System Security Management,
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 allow 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.
Be prepared to spend some time setting this up.
