Can not access website domain name is same as local Domain name
I found problem of my customer, when I acces the website domain name (Example domain name www.abc.com) is same as local domain name(abc.com). I try to created an "A" record that points to www.abc.com so all user can not browse the website from within the office network. But I can access that website with external company network. Base on my research the problem about DNS. Could you please advise me, how to resolve ?
Note: The firewall support team confirmed with me that not issue as firewall.
