Firewall troubles under RH8

[Kitesmurf]

I'm using RH8 from a clean install. I've got Apache2 running and can
connect to it via localhost without any problem. However, as soon as I
try to connect to it via the computer's actual IP address, I get a
"Connection refused" error message. I checked the security/firewall
settings and turned it off; checked the hosts.allow/deny files but to no
use. Well, pretty new to Linux, so could anyone file me in what I'm
missing please?
