Keyword and/or website blocking for a specific range of IPs

[wollyka]

Hi
I used to have several routers (non-asus) and i used to load dd-wrt firmware on them. Since some time, i have a asus-ac68u and i am using asus-merlin (and now the fork).
However, one thing i am missing the most is the keyword and/or website blocking for a specific range of IPs. For example, in dd-wrt, i can specify that i want to deny you-tube access to any range of IPs that i can decide.
Or i can block an entire keyword for example youtube (if a user search for youtube on google, the page won't load)
Here, I cannot use the DNS filtering (openDNS,etc..) since in my country we are behind a double NAT. (The real IP is shared between several households it seems so i cannot configure anything related to OpenDNS or access my router from the internet).
Does anyone knows if it is possible to replicate this behavior using asus-merlin? Can a script be used?
PS: I know there is a dd-wrt version for the AC68u , but for some reason it is not stable enough for me.
Thanks in advance

Keyword url blocking was also available on tomato, but it's now practically useless - most searches can be entered using https - the content not visible on router.

You can use dns poisoning on the router, and use dns filter to force use of router dns - see the adblocking using host file examples. But use of PC host files/ direct IP entry or use of dnscrypt for example on client PC can also bypass anything on the router.

You can block ip ranges effectively using "ipset" - search the forums/wiki

Thanks for your reply. I will search for your examples.
