Question : VPS web hosting query IIS7

Hi all, got a small, albeit ignorant query here.

I have a hosted virtual server (via FastHosts) running a website. I also run an Exchange server at home for the same domain name as the website hosted on the VPS.

The website has an (example) IP of: 99.99.99.99 and the Exchange server has an (example) IP of: 22.22.22.22

I want to use a subdomain to make browsing to the Outlook Web Access (OWA) on the Exchange Server easier e.g. "mail.mydomain.co.uk" which will divert to the OWA on the Exchange Server's HTTP address (http://22.22.22.22/exchange), however weird issue (or not, I don't know, hence the question!) - I can't access the main website (www.mydomain.co.uk) that is hosted on the VPS from my home network (home network is where the Exchange Server is running), nor can I access the Exchange OWA via the subdomain (mail.mydomain.co.uk). I can obviously access Exchange OWA from the internal IP address (http://192.168.0.2/exchange).

Everyone else on the planet (except maybe North Korea!??) can access both www.mydomain.co.uk and mail.mydomain.co.uk (the bit that diverts to Exchange). I can access both resources from my work network, or a friends network, anywhere appears to work - just not from my home network.

On my FastHosts control panel I have both the domain name and the subdomain name setup as you'd expect (all very standard stuff), A Records pointing to the Webserver where the content is hosted (99.99.99.99). Then I have IIS7 configured as standard for the main website, but have a separate website configured for the Exchange OWA access - The OWA website is setup as "mail.mydomain.co.uk and this points to my Exchange Server's external IP (http://22.22.22.22/exchange).

Now, I'm sure the reason why I cannot access the main website is something to do with the way the subdomain (mail.mydomain.co.uk) is forwarded to my Exchange Server - however, why might be causing the issue I'm not sure.

I'd like my subdomain to simply forward to the Exchange Server directly, but I'm sure you can't put "22.22.22.22/exchange" as an A Record.

Anyone be able to offer some advice on the mess above? I'm sure I'm just being overly thick, but you've got to learn somewhere right!?

Thanks,

ok - looking at that picture hints that you have called your internal domain the same name as your external name.

if you have, then you are always going to have difficulties with this. it is accepted that you should always give your internal AD domain a different name to your external domain (i.e. mycompany.local and mycompany.co.uk).

to get round the problem, try creating an A record (mail.mycompany.co.uK) for your internal mail server with the internal IP address and an A record (www.mycompany.co.uk) for your external web site with the external IP address.  If your host changes the IP address of your server then web access will break.
