I use a Dir-655 router in default mode on a dsl line on a small home network. In the past I have used a program called Smoothwall-firewall as a stand alone firewall and my question is, Can I configure my dlink router to provide the same protection level as the Smoothwall firewall and if so, is there a comprehensive how-to configure the advanced features of the router. If someone is familiar with smoothwall system and could help point me in the right direction I would thank you very much.
