I am unable to access one of my customers websites from inside their network. The website is also unreachable by IP address both inside/outside the network. We can however access the website from the URL outside the network (www.xyz.com).
On the LAN I have added a host record (www) pointing to the IP address of the website on the internal DNS servers. It resolves correctly with pathping and tracert tests to both the URL and IP address. I am also able to ping the IP address from inside/outside the network.
I think the problem may be that the LAN domain name and website name are identical (xyz.com for both). I think the issue is that when you type www.xyz.com from outside the network it loads/resolves as just xyz.com in the browser. Am I on the right track? If so anything I can do to resolve on the LAN or do I need to have the web design company fix it?
I am scratching my head on this one as I have setup this up at many sites without issue. I add the host record (www) on the internal DNS pointing to the website IP and it works.
