Site accessible from everywhere but my network dns problem?

Hi i hope someone can help me. Im running centos 7 with cwp latest. Apache only and 1 dynamic ip at the moment. I have NS1 and NS2 pointing to my ip and have also created my own NS on namecheap and have my domains pointing to them NS. Problem i am having is none of the websites or even my server domain will load on my network. I can only view them on my mobile network also ive had various people check from there network and it works fine for them. I have tried Digwebinterface and A record comes up with my ip. The only thing i dont have at the moment is PTR record. My router is a EE smart hub.

Thanks in advance.

DNS points to the external IP.  You cannot go from inside the NAT to outside and back in without a routing table.  If you want to see the sites internally, you need an internal DNS server setup to the private IP address instead of the NAT ip/ with all of the domain names.

It can get confusing very quickly if you're not sure what you are doing.  I'll just leave it at that

Requirements Before the Initialization of CentOS Web Panel installer:

– We only support static IP addresses. We do not support dynamic, sticky, or internal IP addresses.
