Hello,

Weblink https://xyz.com/customers.html hosted publicly not opens only from internal company domain abc.com

Checked that the site is whitelisted in proxy server by the team

Network team confirmed that the ip address of the server hosting the webpage is reachable from the internal network

Our internal DNS is AD integrated in which forwarders are configured to use our company external DNS Linux server for the queries not resolved by internal DNS.

N.B: The same weblink is accessible when the employee is outside of company internal network

Found a solution at the below link but looking for another solution as suggested in the link too if the counts go in 100's wherein the workaround scales badly

Any advice please.....

    As a workaround , I created a entry in local hosts file of the user and now this link can be accessed by the user.

    Had a discussion with Linux External DNS team.Found that the DNS entry is not created in Linux External DNS server and the team has confirmed that the entry has to be created in their side

    Hello

    Thank you for your question and reaching out.

    I can understand you are having some issues accessing External website in Internal network.

    Please try to fist Ping to the website xyz.com , if you are not able to ping then that would be an issue.

    Maybe check any firewalls - possibly something updated & turned on a firewall (rule) that wasn't enabled previously?

    Check AV, etc. The usual suspects.

    Alternatively , Create a new internal zone called website.company.com. Then point an A record to your webserver. Then you would be able to get to the website using that address internally. Probably not the most elegant solution but it should work.
