Hi Felipe,

Apache cannot bind port 80 as non-root (all ports below 1024 require
root access)

You have two choices :

1. If you have a main apache running on this machine, you could use a
ProxyPass directive in httpd.conf

2. from your firewall, you could forward port 80 to port 8000 on your
server. If your server has a routable IP, you could do this locally
using iptables:

$ FGS_PORT=8000
$ INTERNAL_IP=a.b.c.d
$ iptables -t nat -A PREROUTING -p tcp -d $INTERNAL_IP --dport 80 -j
DNAT --to $INTERNAL_IP:$FGS_PORT
