phpbb fails to install

I'm fairly new to Linux so i'm sure this is a setup problem..

When I first installed Virtualmin I used the internal IP as the master IP.. of course nothing could connect to it from outside.. but intall scripts went in fine.

Now I reinstalled and fixed the IP problem.. changed it to my WAN IP.. so everything works, web, mail etc.. except now when I try and install Phpbb or mediawiki I get the following error..

phpBB database configuration failed : Failed to connect to "WAN IP":80 : Connection timed out

it's the same message for either install.. yet squirrelmail went in fine..

I'm guessing this has something to do with the IP change.. but what?

Thanks

Brad
