I meant if he viewed it locally via
http://127.0.0.1
It would also be wrong if his update client isn't working because the domain name wouldn't be pointing to his IP address! Therefore,
http://mobileplaza.no-ip.info "would not exist" and cause time-outs but his IP address would be OK, as you know! Thats why I always hyperlink this way:
<a href="/forum">Forum</a>
This way, no matter wether you use 127.0.0.1, localhost, External IP or domain name, you can always access all links and none will be broken!!
Know what I mean now?
