That means your firewal is off now. If you want to allow that port with the firewall ON, edit /etc/sysconfig/iptables and take a COPY of the line with port 22 (assuming that is allowed in your firewall), change the 22 to 8080, save the file, then type:
service iptables start
If you did it right, you should be able to get to it, even with the firewall on.
