Our DNS server can no longer resolve address after updating our service/modem

We just upgraded to 300Mbps / 30Mbps & receaved a new modem & SecurityEdge.

Now our internal DNS server can no longer lookup address & our LAN workstations can't access the internet. Comcast help, please fix!

 

[root@dc etc]# nslookup comcast.com
Server: 127.0.0.1
Address: 127.0.0.1#53

** server can't find comcast.com: NXDOMAIN


[root@dc etc]# dig comcast.com
; <<>> DiG 9.9.4-RedHat-9.9.4-61.el7 <<>> comcast.com

See the transparent dns proxying thread. Find a CSR and have them escalate this up a tier where they can disable SecurityEdge for the account (takes a few hours). Instant joy.
