Hosting file server through my Business Internet account question about setup...

Got a question:

I decided to not get a static ip address and stay with my dynamic.

Is it still possbile to host my own file server on my account through Comcast? I know it states I can in some posts/pages with a static ip, and it's a low priority file server and a Dynamic DNS service will work fine for me.

If it is possible, are there any things I need to be aware of?

Not talking securing the server, but anything in the setup.
