It might depend where you are on their network, but there's some inconsistencies with the blocking. Port 80 is blocked, but port 443 is allowed. Port 25 is blocked, but 587 is allowed. 135, 137, 139, and 445 are blocked. 8080, 8081, and 10000 get through to my network. Most "other" ports are allowed by default. Like it or hate it, it's a control designed to support their subscriber AUP, which states pretty plainly that customers are forbidden to "host servers" on the home user accounts (http://www.cox.com/policy/ #6). Business lines have such restrictions listed and allow hosting services by policy, and puts the burden of "security" on the customer rather than attempting to enforce by technical means.
