OWA not working from outside but OK internally after adding 2nd Exchange Server

I am testing a migration of Exchange 2003 from a previously upgraded SBS 2003 ( now win 2003 Std via transition pack )

I need to remove the Domain controller from thi original exchange box so I am migrating the exchange to another temporary server, wiping the original box ( Exchange and BES server ), and reinstalling from scratch, and migrating the exchange back, and reinstall BES.
This is only for < 50  users.

I have a test lab and migrating the Exchange to the new Exchange server went fine except for OWA externally.

I then recreated the original server  ( win 2003 STD, and exchange 2003 SP2 )and started migrating exchange to it.
Migrated 3 accounts, and tested OWA, and it does not work.

Router settings are OK, as this worked before on the same original IP, and I had mail working on the 2nd Exchange, with just port forwarding changes.

The problem is I do not even get a login prompt from the external users, although pinging works fine.
FF and IE say server  network timeout or can not be found . Tried both http and https
http://servername/exchange/ 

Same on both servers.

IE does show connecting to the correct IP address on the status bar.

I have checked some similar situation on EE and MS
http://support.microsoft.com/default.aspx?kbid=883380 

but I am not sure if it applies since all is OK internally.

Some stuff I have checked
I changed the Default Domain name in Access -authentification of the Exchange Virtual Server properties, since it had the shortname alias there.

I tried comparing the working server with the Lab setup, but there are strange reisdues form the SBS transition.

Anything I can check or try to fix this ?

Thanks !

If it works outside but not inside almost has to be a firewall thing. Can you try accessing a static html page on that server just to verify port 80 is being directed to the correct server.

Revere that works inside but not outside. Hit and html page from outside using http and https just to verify it works.

I restored to a previous image, and I was prompted for a certificate on a Public folder, so that means at least the routing appears OK

Any other suggestions ?

Old image of computer works OK including Mail and public, so this is definitely not a router issue.

OK , the issue appeared to be related to the netscreen firewall. It is blocking port 80 apparently, As soon as I installed a certificate, I could use SSL and port 443 which is what I need.

Thanks !
