My site, bfna.netlify.app, is accessible from anywhere on the internet EXCEPT for the company’s internal network (which has the bfna.org domain).
To date this is what we tried:
- updated the local DNS servers with the new www.bfna.org ip address (188.8.131.52). An NSLookup resolves it to the correct address……but still can not connect with a browser.
- Tried adding / removing firewall rules to allow access of all packets to and from this address.
- Using the network shell set the dns and reset the winsock.
- Clearing the cache and ARP tables on the DNS servers.
The message we get is “server refused connection” and it ONLY happens when internal DNS servers are used to resolve the www.bfna.org domain name.
Changing the DNS servers of the internal machines to Googles DNS servers (184.108.40.206 and 220.127.116.11) allows the access from inside the network. But, of course, we lose access to the local servers.
Is there anything that would hinder a machine from the internal network of the bfna.org domain from gaining access to the website when using their internal DNS servers to resolve the ip address?
Any hints on how I can solve this problem?
