RWW/OWA Not Working Externally

[grahameg61]

Hi folks,

We've been running SBS2008 for about 9 months with no problems. A week ago, external access to RWW/OWA stopped working (nothing in Event logs to suggest why) and I can't seem to get it going again.
Access to both RWW and OWA internally is fine.

Browser response is "IE cannot display the webpage" (same result with other browsers)

So far I have:
- spent about 12 hours trawling through blogs, forums etc. trying to find an answer :-(
- checked router port mappings: TCP Ports 443, 987 and 3389 are mapped to server IP
- checked IIS7 bindings for SBS Web Applications website: Port 443 mapped to server IP & certificate is valid
- checked folder permissions: Users can Read/Execute, List Folder Contents, Read
- checked DNS records: Forward Lookup Zone for remote.mydomain.com exists with Host (A) record mapped to server IP
- tried connecting via

https://my_router_ip_address/remote

- same result
- ensured server patch status is up-to-date.

I can ping remote.mydomain.com and resolve the name to our router's static IP address from outside our network, so I'm assuming the DNS record our ISP created is still working.

I'm starting to lose sleep over this, so any suggestions would be greatly appreciated.

try running the wizards again in the sbs console, check that the websites are enabled in the sbs console.

Thanks Paul,

The problem has been solved. Running tracert indicated we were getting blocked by our ISP.

I recalled (a bit late, I know, but it's been a very long year already) that we'd changed broadband plans with our ISP recently and the updated plan included new security features - one of which was a firewall that was enabled by default (and blocked ports 443 & 987).

I appreciate you taking the time to respond.
