dnsmasq.conf.add and DNS filtering

[rbirkby]

I'm on 376.49_2

I have noticed that adding a DNS entry into the dnsmasq.conf.add alongside setting DNS filtering to ON in Parental Controls will ignore the dnsmasq.conf.add.

Specifically, I wanted to have OpenDNS family search in parental controls alongside setting forcesafesearch using dnsmasq as described here: https://github.com/RMerl/asuswrt-merlin/wiki/Enforce-Safesearch

I can't see anything in the changelog since 376.49_2 - so is this still an issue?

It's not an issue, that's how it's designed to work. By enabling parental controls you are telling the router to bypass other DNS servers (including dnsmasq) and only use the one specified.

Thanks. That wasn't clear. Instead, I've pointed to the OpenDNS servers using the dnsmasq.conf.add file itself.

But remember that is not as fool proof as the parental controls ...
The child can just point their machine to a different DNS server.
Parental controls blocks the child from using any other DNS server.

Good point. It would have been more accurate if I had said, "By enabling parental controls you are forcing the client to ignore other DNS servers (including dnsmasq) and only use the one specified"

As a workaround, you may turn off DNS filtering and do it manually:

# cat /jffs/configs/dnsmasq.conf.add
### Samsung S3 mini
dhcp-host=E4:40:E2:AA:BB:CC,set:kids

### Samsung Tab 3
dhcp-host=64:B3:10:AA:BB:CC,set:kids

### SkyDNS for kids
dhcp-option=tag:kids,option:dns-server,193.58.251.251

Does this override client dns settings?

I presume only works for dhcp.
