Hi,
I’m having some problems with OWA. It is the first time I have installed Exchange 2010 (Other than SBS2011), I think the issue is possibly dns related but if possible I would like to have some advice before delving into the problem a little further.
The scenario:-
Windows Server 2008 Enterprise Ediiton with 2 NICs. Internet NIC facing the router with static 192.168.1.100, and Private NIC with static 192.168.16.100. The private NIC is serving DNS with forwarders, NAT is running, the network works perfectly.
I have then installed Exchange 2010, and set up send and receive connectors for mail.internetdomain.co.uk, as well as some test mailboxes etc. I have created a local dns forward zone for mail.internetdomain.co.uk, and within that zone have an A record pointing to my Internet facing NIC 192.168.1.100 as well as name server entries for the server itself (server.localdomain.local, both internal ip’s listed on the entry). In the dns of my domain provider (public dns) I have an A record set up mail.internetdomain.co.uk to point to my ISP provided public static IP address as well as an MX record set up to do the same. On testing the mail element works fine.
Outlook anywhere has been enabled in Exchange and the default website in IIS7.5 has an OWA directory of http://mail.localdomain.local/owa and https://mail.internetdomain.co.uk/owa utilising ports 80 and 443 in the bindings.
Internally OWA works fine on both http and https (even using https://mail.internetdomain.co.uk) but externally I cannot reach any of these websites. As a very quick check (as the server is not yet live) I popped the server into the DMZ and still could not reach these sites. I may be missing something very obvious as Exchange is not my strong point, and apologies if I am, but any help or advice on this would be much appreciated.
Thank you.
Jamie
