Primary DNS not working

I have a Windows Server 2016 domain on a /24 network.  I have the DC setup as DNS and DHCP servers.  The gateway is a Xycel router.  The client computers use both DHCP and static IP from the DNS server. The problem I am having is two-fold. When I state the DC DNS IP as the primary DNS server (DHCP also list this IP as well).   1. Having problems getting out to the outside world.  I am seeing either No Internet or Slow Internet (problems resolving and more than 30 hops on tracert), and some pages are loading incorrectly.
When, I add the Google Public DNS 8.8.8.8 as the secondary DNS server, the Internet seems to work fine.  Pages resolve and hops and ms are normal.
So, I know I have a DNS issue going on.  
Question: Would DNS forwarding correct this problem?  If so what IP address do I forward to?  
Google Public?   The external IP address for the ISP?   The internal IP address for the Xycel router?
Looking for answers?
One other note:  This is a clean install (not a migration or upgrade)
Thanks in advance

Hi Van!
You will want to set your DC to forward and cache queries for your domain within DNS Manager.

Do you have primary and secondary DNS servers being provided by your ISP? While Google is ok, I would recommend using your ISP or secured DNS for your forwarding servers.

I hope you configured forwarders in DNS. Please try to use your ISP DNS server.

Your ISP would be most ideal, but Google is acceptable as well.

I'm assuming that all of your internal traffic was working perfectly normally. And just out of curiousity, what DNS servers do you have set in the following places:
1) router
2) server (I know you mentioned it's the DC and DHCP server)
