Exchange server 2007 owa problem.

Is it possible to have a simple configuration for owa?

Software installed on our server:

Microsoft .NET Framework 2.0
Microsoft .NET Framework 3.0
Microsoft Exchange server 2007
Microsoft SQL Server Desktop Engine (SharePoint)
Microsoft Windows Share Point services 2.0
MSXML 6.0 Parser (KB927977)
POPBeamer for Exchange Server
Remote Administration Tools
Windows Internet explorer 7
Wndows server 2003 R2

Services in use:
dns service
dhcp service
wins service
Routing e Accesso remoto

Server has two lan card. One internal and the second external. The external card is connected to a router and the internal is connected to a lan.

I don't really understand what your question is.

Having two NICs is not something I recommend, so I would suggest changing that, possibly teaming the NICs instead.
Any reason you are using POP Beamer instead of SMTP delivery which is how Exchange is designed to work?

Why 2 Nics?
I reeded that to use vpn access from internet client, is necessary to install Remote Access Routing service.
So our server need two nics.
For VPN is necessary Remote Access Routing with 2 card with two different lan segment.
example:
10.1.15.21 internal
10.1.16.21 external

I've find this information on this italian link:
http://www.sysadmin.it/pages/guide/guide.asp?ID=67
you can chek to see what i've made on my server.

Pop Beamer:
read this link:
http://www.slipstick.com/exs/popconnect.asp

Downloading mail from a POP account into Exchange Server in general is not a supported configuration (though you wouldn't know it from the proliferation of tools to accomplish this). However, Microsoft does provide an Exchange Connector for POP3 Mailboxes for Small Business Server, having licensed Internet Mailbridge from Acotec. It's still not a supported configuration for full Exchange Server.

I know what POP Beamer is. However most POP3 connectors are garbage and not worth spending any money on. The POP3 connector in SBS is designed to help the move to SMTP - which is why it is crippled.

Using a VPN doesn't need two NICs. I have lots of machines that use VPNs. Dual homing an Exchange server is not something I would recommend.

However I still don't understand what your actual question is.

Does Powershell have you tied up in knots?

You do have to use Routing and Remote Access for VPN, but that doesn't mean you have to use two NICs. This looks like you are trying to ask Windows to do routing. Use a router for routing, not Windows.
I never recommend dual homing Exchange, plus you cannot have two default gateways. It just makes networking more complicated than it could be.

Therefore before continuing I would simplify the Exchange server's configuration by disabling one of the NICs. If this is a dedicated Exchange server then it should be used for just that - Exchange and nothing else. If you want to have VPN connections coming in, then use another machine for that.

On the server itself, if you browse to http://locahost/owa - what happens?
Have you tried to replace the SSL certificate that Exchange 2007 creates during the installation?
Have you checked which IP address the default web site is bound to in IIS Manager?
