Hi Jarkko,
you say you can access the pages on localhost. Do you use the alias "localhost" in your browser?
Look in your tcl config file. Change address to something different than "127.0.0.1" - if it is set to this one. "127.0.0.1" can not be reached in the net.
You can comment the aolserver line in /ect/inittab out and start the server by hand (foreground mode -f).
Look at the output, AOLserver will output the address it "binds" to. Try this address (and port) from different browsers from the network.
Example:
http://192.168.20.20:8080
If this does not work and no firewalls are running on the webservers machine, try if you can reach the webserver at all. Ping it. Traceroute it. Scan it.
Hanjo.
