Discussion: Firewall/Router

What do you use at home and what are your thoughts on it? What defense/security features does it include?

PLEASE READ THIS.IT IS VERY IMPORTANT

Allow your discussion posts to be detailed and capable of sharing knowledge, ideas and points. You must discuss the topic using your own words first. Using your own words indicate you understand the topic of discussions. Secondly, you must cite your sources in-text. This is necessary to justify your points. Sources from several sources showed good research abilities. Lastly, you must provide references at the bottom of your post. A discussion post without justification with sources does not show proper research abilities. A terse and not detailed discussions represent post that would not provide enough sharing of knowledge or proper understanding of the topic. DO NOT just copy and paste a sentence from online with citation at the end as your own discussion. I have not asked for definitions, I asked for discussions and will not buy this. You must show understanding of the discussion topic by using your own words to describe the topic and then justify that with sources.
