No...as long as you've told apache to listen on 80 in it's config, you don't need to specify port 80
can you access your website over ipv6 internally?
Check in the windows advanced firewall and make sure you're allowing port 80
if you're running Windows 7 pro, any reason you didn't use IIS?
"can you access your website over ipv6 internally?"
How to do ? I know "localhost" or "127.0.0.1"for IPV4 , What is for IPV6
" Check in the windows advanced firewall and make sure you're allowing port 80"
Firewall is set to off. and I also set allowing port 80.
"if you're running Windows 7 pro, any reason you didn't use IIS?"
because I think apachee is so common , should be easier to set up , However , I will switch to IIS if apachee is fail .
