You'll first want to make sure you're not blocking port 80 on your firewall - probably iptables or ipchains.
You'll also want to try connecting to the machine using its external IP address (i.e. 18.104.22.168) instead of the fully qualified host name (i.e. mybox.homelinux.net) If that works then you've got a DNS issue which should be easy to resolve.
You can check the DNS entry using nslookup or dig. Make sure the IP address is correct.
That should be enough to get you started.
