dsl

For the last few months, I've been using a server on my home network for basic backups and hosting some small websites. Up until this past week, I've been using Comcast (cable) as an ISP and now that I've moved into an apartment, I'm using AT&T. (DSL)

I've set up dynamic DNS and I can verify it works externally. However, I can't seem to access the public address from within the local network. Is there something DSL does differently from Cable that makes this frustration possible?
