Smart TV cannont connect out

[Nick_tmp]

I have an LG tv that cannot connect to any external sites. It says it's connected to the internet. Help! I have an rt87u with the latest firmware as of 01/03/19. Please and thank you. If this has been brought up before, please link me to the thread. Thanks!

First thing to do, reset your tv or the network in your tv settings

That was the first thing I tried of course. It connects fine when going out of my internet providers router also. I’m trying to keep everything inside my “moat” and use the network space between the xfinity modem/router and my Asus router as a DMZ. Everything else can connect fine when connected to the Merlin router, just not the smart TVs. One LG and one Vizio.

Do you have a custom DNS set up? I had mine set to OpenDNS and had blocked South Korea so my Samsung couldn’t connect.

Great suggestion! I’ll try that today and share my findings.

That’s exactly what the issue was. Thanks for the suggestion! I tried using quad9 and then creating an exception for the tv, but it still had issues. It appears the global quad9 setting overrides a “no filter” setting for a specific MAC in the table. So if I want to use a filter for the rest of the house, I’d have to manually add individual MACs to use it and have the global setting to “no filter.” Correct me if that statement is incorrect and I’m just not realizing what I’m doing wrong.

"No Filter" will just allow the client to use whatever DNS is provided on your LAN DHCP page, or else the router itself, which will use your WAN DNS settings. It just means it will not intercept and override the DNS requests from the client. What are your LAN DHCP DNS servers set to (hopefully blanks)? How about your WAN DNS servers?
