Apache box behind Openbsd

Hi,

I have an apache-php website running on windows server 2003 port 80, i have correct rdr rules that pointing my web server, i can view website inside my LAN, but i can't view page outside of my network. I've checked all dns- ip settings, everything's fine but problem continues. I've read at some forums that apache doesn't recognize rdr rules from openbsd, so how can i publish my site ? Thanks...
