Microsoft Report Designer - Could not connect to report server (after moving to DMZ)

Thanks in advance for any help / insight you can provide:

When publishing reports via Microsoft Report Designer - everything works find when the server is on the local subnet.

When I move the server to our DMZ, I get the error:

 Actual error message...
I can, however, go directly to the URL directly...

Looking at the firewall/router, I cannot see anything blocking the traffic.

Any idea what might be causing this?

Once you move your server from inside to outside your DMZ, doesn't the server URL change?  For example, you show in your screen print:

http://ftw-sql-prd03/ReportServer_SSRS1

Doesn't this become:
http://ftw-sql-prd03.yourcompany.com/ReportServer_SSRS1

HTH,

Kent

Kent -

Thanks for the reply.

No - unfortunately the URL doesn't change, as while this server is in the DMZ, my predecessor setup the current internal domain to be the same as our external domain.

The part I don't understand is why IE lets me straight to the site, whereas the publisher can't reach it...

Does anyone know which specific ports Microsoft Reporting Services communicates on for securities?

Thanks,

Ken
