Need help, I am new to this.

I downloaded apache 2.2.4 (win32) mysql and phpbb2. Installed it on a winxp machine. localhost and ip 127.0.0.1 work fine on same machine.
Localhost/phpbb2 lets me install and configure phpbb2, no problem. On the pc running apache, mysql and phpbb2 as well as a remote pc and wireless router, 192.168.1.46 displays index of the webroot folder. If I type 192.168.1.46/phpbb2 on either pc I get 403 Forbidden. I would like to have anyone who can connect to my wireless, join my phpbb2 forum. No Internet access will be connected to this server once running.

Extended service info
Ip and port 0.0.0.0:80[all], 0.0.0.0:443[all]

System info
Ip address 192.168.1.46[private] <can this be public? How?
127.0.0.1[local]

I must be missing somthing vary stupid in httpd.conf or httpd-ssl.conf.

Usually a 403 error is a permissions problem but in your case, you might have to add 192.168.1.46 to the hosts file. 192 addresses are not routeable outside the LAN, if that's what you mean by public.
