I have a new Web Server that I setup here in the office. Access via the public IP or A record works fine both inside and outside of our LAN. I had setup an alias to redirect to a specific folder of the web server as follows:
A Record: clients.domainname.com --> points to Public IP of Web Server
Alias: othername.domainname.com --> points to clients.domainname.com/sit
The DNS is managed through godaddy.com
This works perfectly outside of our LAN. However, I notice that the alias does not work inside the LAN.
By chance I entered in http://www.godaddy.com
to get support and realized that I get a cannot display this webpage error. Only https://www.godaddy.com
works. Same thing I get for my alias, though entering in https does not work.
So I figured my LAN must be blocking or misconfigured for handling http://www.godaddy.com
or my alias.
My firewall support says it is not the firewall and sounds like a DNS issue with our internal server.
