I'm trying to use the access restrictions to block my LG TV from being able to update the firmware, by blocking the three sites mentioned here:

https://github.com/joey-astrologo/OLED55-65B6-Downgrade

It doesn't seem to be working at all, and I'm lost as to what I'm missing. Here's what I've done:

a) I enabled policy 1 and titled it "LG Updates".

b) I clicked Edit List of Clients and use the MAC address section to enter the MAC address of the TV (this is all I should need correct?).

c) I choose the "Filter" option.

d) I left it set to every day and 24 hours.

e) I entered the three domain name (snu.lge.com, lgtvonline.lge.com, su.lge.com) under Website Blocking by URL Address, and applied.

This simply doesn't appear to be working. Am I missing something there?

EDIT: Meant to mention that I'm running 10-20-2017-r33555 on a Linksys WRT1900ACS.

Thanks!

2 ways to go

1. block those sites via DNSmasq commands
add those lines on additional DNSmasq option

address=/snu.lge.com/0.0.0.0
address=/lgtvonline.lge.com/0.0.0.0
address=/su.lge.com/0.0.0.0

or

2.block them via iptables - just add those lines on administration>commands and click save firewall

iptables -I FORWARD -s 136.166.4.110 -j DROP
iptables -I FORWARD -s 63.123.46.16 -j DROP
iptables -I FORWARD -s 96.17.177.24 -j DROP
iptables -I FORWARD -s 96.17.177.9 -j DROP

you can do both if you'd need

Awesome beyond words! The DNSmasq option works perfectly for me. I was leery of trying to use iptables as those domains tend to be aliases to Akamai etc, and the IPs might even change.

Thanks!
