Ok @KW. , last 2 tries:
And
If it does not work, I will disconnect Entware tomorrow on my router (and hopefully have exact same environment than you have for testing) and/or wait for @kamoj ’s solution once he’s back home.
Code:
echo -n "say y: "; echo "answer: $(head -c1 /dev/tty)"
Code:
echo -n "say y: "; A=$(dd ibs=1 count=1 2>/dev/null); echo -e "\nanswer: $A"If it does not work, I will disconnect Entware tomorrow on my router (and hopefully have exact same environment than you have for testing) and/or wait for @kamoj ’s solution once he’s back home.

Thank you for calling me a big guy, I’m not at the level of @kamoj or the ultimate @Voxel .
As you guessed, none of those are working. I give up for today.
Have a good Sunday

Ok, back and found it.
Apart from this there is also a trick involving sed and tty...
I don't think you need any instruction, so here is my current solution (one of many):

Ah! Trap the stdin inside a while loop so ash does not receive it as a command, smart!
Thank you @kamoj
So, @KW. : this should work:
And I will be able to update my script (tomorrow) to fix the asking yes or no bug while trying to upgrade (and fix that in install.sh as it asks a question too).

Nah Im done testing for today... haha sorry just kidding Im never done. I think something happened. You guys are so impressive! I love the comment "Ah!

For info, this iptables error you get is not coming for the script. Apparently, native NG setups are throwing some errors (likely to be without incidence because all routers sold are concerned).
Interesting. Did it do that before?
Anyway, not major. You can remove doing exactly:
Code:
cd /mnt/optwareThen
Code:
rm -rf fblGood evening
The blocklist works very fine and as before I notice no drawbacks on my networks performance. All i got with your script is a safer network Now on my wish list is the iprange. I hope it is possible to get in the script for r9000 sometime in the future.
Your script is here to stay thank you allot for sharing it!

Thank you!
I am glad this is useful to other people
For iprange on R9000 (without Entware), I will need to ask @Voxel as he has the compiling environment.
Entware was easy to install for me following Voxel’s readme, but maybe it’s a little different for R9000.
