I bet firewall is on/NAT does it.

You can remote check your webserver from home by using here:

http://watson.addy.com/

Just type in your IP, and see if it can connect to webserver.

But I do believe firewall is on default on Redhat (certainly from 7.1 upwards).

You will need to open ports 21 (ftp) and 80 (http).  I am not sure what NAT does though on your network configuration - that can certainly foul things up.
