I recently upgrade my Allo<\/a> wireless to using their Blast Router. After I upgrade to the Blast Router, my DVR and set top boxes (STB) could no longer connect. Working with their support team, there was a few things that they thought that it might be because I changed the default IP range away from 192.168.1.0\/24. Another thought was that the STBs needed the DHCP turned on as I turned it off. I also run PiHole<\/a> on my network for DNS and DHCP. Lucky for me I have my PiHole sending its data to Splunk<\/a>.<\/p>\n\n\n\n

After resetting the STBs and Blast Router to factory defaults with the Allo Support team, I went through testing each part of the theories. I changed the default IP range and rebooted the STBs and everything connected. I changed the DNS to PiHole and rebooted the STBs. The STBs did not connect. I changed the DNS back to the internal and everything connected. I changed the DHCP to the PiHole and rebooted the STBs with the DNS pointed to the internal DNS server. After a reboot, the STBs connected with out an issue. I then changed the DNS to point to the PiHole DNS server and rebooted the STBs. They were unable to connect. So the issue is the DNS server in PiHole.<\/p>\n\n\n\n

I jumped over to Splunk after grabbing the IPs for the STBs. A quick search of:

index=”pihole” (src=”172.16.24.200″ OR src=”172.16.24.201″ OR src=”172.16.24.202″) answer=NXDOMAIN<\/em><\/span><\/p>\n\n\n\n

showed me that there were some domains that PiHole wasn’t able to resolve.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

A quick stats command and I have a list of the domains that the STBs were looking for.<\/p>\n\n\n\n

index=”pihole” (src=”172.16.24.200″ OR src=”172.16.24.201″ OR src=”172.16.24.202″) answer=NXDOMAIN
| stats count by query
| sort – count<\/em><\/span><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Now the question is why are they failing and were should they go? Doing a nslookup externally comes back empty and this is why PiHole was failing.<\/p>\n\n\n\n

% nslookup pflocal.iptvtg.com 8.8.8.8

Server: 8.8.8.8

Address: 8.8.8.8#53

** server can’t find pflocal.iptvtg.com: NXDOMAIN<\/span><\/p>\n\n\n\n

I can still ask the Blast Router what it has for DNS for those addresses<\/p>\n\n\n\n

% nslookup pflocal.iptvtg.com 172.16.24.1

Server: 172.16.24.1

Address: 172.16.24.1#53

Name: pflocal.iptvtg.com

Address: 10.131.7.82<\/span><\/p>\n\n\n\n

Now I have two ways I can solve this issue.<\/p>\n\n\n\n

  1. I can forward any unknown domains to the Blast Router and it will forward them along<\/li>
  2. I can get the list of domain requests, do a lookup for them to the Blast Router, and add them as a local DNS entry.<\/li><\/ol>\n\n\n\n

    I went for #2. Below are the list of domains that I needed to add to my local DNS:<\/p>\n\n\n\n

    Domain<\/strong><\/td>IP<\/strong><\/td><\/tr>
    appstore001.iptvtg.com<\/td>10.11.154.10<\/td><\/tr>
    mdspf301.iptvtg.com<\/td>10.11.150.10<\/td><\/tr>
    pflocal.iptvtg.com<\/td>10.131.7.82<\/td><\/tr>
    time.iptvtg.com<\/td>10.10.5.100<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
