Unable to access browser-based app from outside the firewall
Posted on 2014-03-04
I cannot access/launch a browser-based app (Silverlight) from outside the router (i.e. Internet). I am getting "This page can’t be displayed" error.
•I updated our external DNS record to point to the internal server FQDN. When I ping the FQDN, it returns the external IP address of the router.
•On the router, I have port 443 forwarding to the IP address of the correct server.
•I turned off the server software firewalls, but still no joy.
•I installed a wildcard SSL certificate.
Again, everything works fine from within the router (without using lmhost file). I think the problem may be DNS related, but other than what I've already done, what else might need to be changed?
