Incoming ports 80, 25, and 21 are blocked. To prevent home users from running HTTP, FTP, and Mail servers from their residence. Business does not block these ports.
Update: Health Edge beat me to it as there is actually a support article describing each and every port and reason as to why it is blocked. Looks like 21 is not blocked for FTP.
*SMTP is only permitted outbound to Cox-provided SMTP servers. (For Port 25) (Example smtp.cox)

Ports Blocked or Restricted by Cox High Speed Internet.

PS. FTP(21) is NOT blocked to best of my knowledge.
