Comment: My WAN Connection (DSL)

(See in situ)

My WAN Connection (DSL)

has a static, public IP Address. I paid $5.00 more a month to get a public IP. By default, the phone company here gives a connection with a private IP Address which is already behind a NAT server. Then when you connect your computer to your router it makes it two layers deep in NAT, with absolutely no way to expose a server. Definitely worth it to pay for the public IP.

When I lived in California and had a cable modem, they did not give an option for a static IP, although, for the most part, it rarely changed. I was able to set up servers by using a dynamic DNS account.
