Bypassing ISP Incoming Traffic Restriction on Port 80

A couple of days ago, my friend Jeffery registered a new domain name, and he pointed that domain to his server located in his apartment. But his ISP, Cox Communications, blocked some common ports, namely 80, 443. Basically, with these ports being blocked, one could not easily run an Internet-accessible website. As a result, Jeffery had to append the port number explicitly, which is not only a pain in life but also a significant impact on SEO. So he came to see if I can help him out.
