Hi @Amol Khedekar ,
According to your description, do you want to access SharePoint 2013 outside the farm? If my understanding is wrong, please contact me in time.
If yes, you can try to use the two methods:
- Using a VPN, access the SharePoint site as if it were from inside the network.
- Publish the SharePoint server on the Internet.
Here is a similar issue for reference: Access SharePoint 2013 outside server farm with AD Users
Hope it can help you. Thanks for your understanding.
