What is a firewall?
A firewall is a piece of software (or in rarer cases, hardware) that filters your connection to
the internet. Generally, it does provides both incoming and outgoing protection. This is
accomplished by ignoring inbound connections, and by warning the user that an outbound
program is attempting to make a connection and giving the option to allow or block that
connection from occurring. Additionally, routers have built-in firewalls which the owner can
adjust and circumvent. Mediacom's internet connection to your home is not filtered in any
way. We do not block any kind of connection. It is up to you to have a firewall in place if
you choose to, but we do recommend that you do.
