Question: Why is the bing search engine bad?
Installed this script, but noticed that one of the addresses "a-0001.a-msedge.net " resolves to the same IP (13.107.21.200) as bing.com, so it blocks the bing search engine. Removed this entry and bing search works again for family members.
 
all of these are safe to delete and i took most of em with the exception from shodan and the android rootkit servers of the wiki, havent had time to go thru em but its nice that you two have so lets delete some of the example list.
 
i have firewall-start script with iptables firewall rules for specific port....so, if i add this privacy-filter script i think not working? is this my firewall-start script ok?
Code: 
#!/bin/sh

iptables -I FORWARD -p tcp --dport 1244 -j DROP
iptables -I FORWARD -s 95.159.192.0/18 -p tcp --dport 1244 -j ACCEPT
iptables -I FORWARD -s 178.58.0.0/16 -p tcp --dport 1244 -j ACCEPT
iptables -I FORWARD -s 188.196.0.0/14 -p tcp --dport 1244 -j ACCEPT

either store my script as a separate script or it on ITS OWN dont mix and match.

and your issue has been answered in the thread not gonna cover it again on how to check if its working or not.

read the thread!
 
so, firewall-start not working with two different scripts inside....just like to know....
 
either use this filter as standalone opt or jffs really doesnt matter to me but dont enter stuff into it else no support.

its in the OP

either a cronjob or as a separate entry in firewall-start

watch iptables -vnL FORWARD | grep privacy

to see if it blocks

FYI its not gonna tick away right away so dont post 10 sec afterwards saying its not working give it day atleast.

Try to ping one of the blocked IP ( say ping -c 5 216.117.2.180) and see if the count increases

i got this: btw, i do not have privacy-filter.list.....i see in script that privacy-filter will automatic install and update?
Code: 
admin@RT-AC3200-0000:/tmp/home/root# ping -c 5 216.117.2.180
PING 216.117.2.180 (216.117.2.180): 56 data bytes

--- 216.117.2.180 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss

Yep...looks like its blocking ok then.... try the same with a good IP (ping -c 5 8.8.8.8) you should get 5 packets received and zero packet loss

yes i receive 5 packed and zero loss....should we have some logs in syslog? how to check how many times a day, week we get requst to connect from those hostname addresses?

You can do "iptables -L FORWARD -v" and that will show you the packets and bytes that matched the rule... in this case your privacy filter
 
i can ping all these hostname in privacy-filter.list? is this normal? I imagined that all this is blocked?

where are you pinging from?.... open a command window on a client machine and try.... its a forward rule so it should stop packets passing through the router.

Also, perform an nslookup for some of the hostnames. Most likely, the hostnames for some on the list are resolving to a local IP. For example, a.ads1.msn.com resolves to my pixelserv server:
Code: 
# nslookup a.ads1.msn.com
Server:        192.168.222.1
Address:    192.168.222.1#53

Name:    a.ads1.msn.com
Address: 192.168.222.2
The ping succeeds to the local pixelserv server, not the distant suspect host:
Code: 
# ping a.ads1.msn.com
PING a.ads1.msn.com (192.168.222.2): 56 data bytes

This is expected behaviour. ping and nslookup will resolve a domain name through dnsmasq. If dnsmasq has a hosts file redirecting the lookup to where pixelserv is listening , you will see the ping response from pixelserv. Other lookups will make it to the firewall and if they match the rule will be dropped.

Strange...its working ok for me... i do an nslookup i just get the cached IP from dnsmasq and the ping packets are dropped.

You haven't rebooted the router since you ran this script have you?..... the iptables and ipsets are in ram so they have to be reapplied if so.

The same here for certain hosts -- it depends on whether another tool (e.g., AB-Solution) also affects the DNS resolution for the host:
Code: 
$  nslookup census1.shodan.io
Server:        192.168.222.1
Address:    192.168.222.1#53

Non-authoritative answer:
Name:    census1.shodan.io
Address: 198.20.69.74

$ ping census1.shodan.io
PING census1.shodan.io (198.20.69.74): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
^C

i have no idea what could be wrong.....i will remove this script temporarily.....
EDIT: strange, some hostnames not pinging, some pinging and some redirecting to computer....
