Hi,

Initially the website I installed (V4.3.6) on port number didn't work. When I added UsePortNumber key in config file the website in local network started to work. but I can not see it externally and I get "Cannot display web page" error message.

DotNetNuke 4.3.6 works with using PotNumber on the local netwrok like http://10.0.0.20:8066/DotNetNuke

but it doesn't work when I use external domain name looking at the same server. like http://www.mydomain.com:8066/DotNetNuke

We do have other websites which we have access externally without any problem.

I have tried to put the domain name into PortalAlias with all different type of combination without any luck

http://test.dotnetweb.co.uk:8052/EspAdmin  This one works

http://test.dotnetweb.co.uk:8055/DotNetNuke  Doesn't work

Baring in mind that I can go to errorPage.aspx by http://test.dotnetweb.co.uk:8055/DotnetNuke/ErrorPage.aspx

I actually installed it in a differnet server which the port 80 is open for host header and I put the domain name into host header value like below, and still the external link doesn't work

My local address is http://10.0.0.151:7065/DotNetWeb  which works perfect. My external address is http://www.dotnetweb.co.uk/DotNetWeb which daesn't work. But I can go to http://www.dotnetweb.co.uk/DotNetWeb/ErrorPage.aspx  or bring an image from web like http://www.dotnetweb.co.uk/DotNetWeb/images/action.gif

Here is my records in PortalAlias table

PortalAliasID, PortalID, HTTPAlias

 1, 0, 10.0.0.151:7065
 2, 0, http://www.hdotnetweb.co.uk/dotnetweb

Do I need to do anything on Default.aspx. I haven't touch it so far and it's still the one came from install zip file.

Please help on this and your help will be highly appreciated.

Many thanks

Ben
